New Zealand Hepaticae (Liverworts)—VII
A Review of the New Zealand Species of the Genus Lophocolea With Notes on Chiloscyphus

[Read before the Hawke's Bay Branch, October 3, 1951, received by Editor, November 26, 1951]

Summary

Introductory remarks on the variableness of the species; key to 31 species; descriptions of same, including 2 Tasmanian species recently detected in New Zealand, L. amplectens and L. paucistipula, and 2 new species described in Latin, L. innovata Hodgson sp. nov. and L. fiordlandiae Hodgson sp nov., and one new variety, L. helmsiana var subparallela Hodgson var. nov, 2 new combinations, L. stronglyophylla (Tayl.) Hodg. comb. nov., and L. turgescens (Tayl.) Hodg. comb. nov.; 12 species of Stephani's definitely reduced to synonymy, also 7 of Herzog's, 1 of Schiffner's and 1 of Pearson's. Notes on Chiloscyphus and Heteroscyphus, with correction of errors in a former paper on Chiloscyphus, and new localities of rare species Thirty-five figures Types of new species in Herbaria of E. A. Hodgson and K. W. Allison.

It is with much trepidation that one undertakes the revision of a genus such as Lophocolea, and one encounters expected difficulties almost from the outset. In New Zealand the species are so variable and in such a fluid state, and the interrelations within certain groups are so manifest, that with the Old World conception of a species being what it is, it is no wonder that the number of described species has reached at least 50, not including those already synonymized by Mitten. With the number reduced to 31, as in this paper. it is hoped that the position is now less confused.

One notices early on a seeming tendency in the leaf-apices for the teeth to disappear. Even in L. bidentata, with 2 long, attenuated laciniae, there are instances in which one or even both of these have become obsolete. The matter of disappearing stipules is another difficulty, which appears to bring one subsection of the genus close to Jungermannia One wonders, too, why in some instances small cells are mixed with larger ones. as though the plant might be in process of changing from one to the other, and there seems to be no fixed rule for uniformity of cell-size in one particular species As in Plagiochila, there are numerous types of cells throughout the genus.

The originals of 9 of the species were from Auckland or Campbell Islands, collected by Sir Joseph Hooker, and to recognize the same species from the mainland, one has to allow for poor development and for possible geographical differences. The same may be said of species whose originals were from Tasmania or Australia.

Though widely distributed throughout the world, there are comparatively few species in the Northern Hemisphere, whereas in South America, Australia and New Zealand they are very numerous. L. Rodway describes 44 Tasmanian ones, but admits that they might not all be good species.

Lophocolea differs from the related genera Chiloscyphus and Mylia (Harpanthaceae) in its triangular-prismatic perianths, but this mark of distinction is sometimes hard to recognize.

– 330 –

Stephani has divided the genus into 3 sections, Integrifoliae, Bidentes and Heterophyllae, with numerous subdivisions in each section, with which I have not bothered.

Genus Lophocolea Dumort

Jungermannia Sect. Lophocolea Dumort., Syll. Jung., 1831.

Lophocolea Dumort., Rec. d'Obs., 1835.

Plants minute to large, mostly on earth, but sometimes on rotting logs or rock, whitish, yellowish, or olive-green; aquatic forms dark-green to blackish, sometimes brownish, mostly soft and flaccid. Stems subsimple or irregularly branched, branches arising from the ventral angle of the leaves, mostly creeping, occasionally suberect. Leaves succubous, inserted nearly longitudinally in the majority of cases, ± decurrent antically, bifid or subtruncate or rounded, with margins occasionally dentate. Stipules commonly present, usually bifid with a lateral tooth, connate on one side with the leaf, but less often free, or connate on both sides. Cells very diverse in type. Inflorescence terminal on the main stem or branches, subfloral innovations sometimes present. Involucral leaves resembling those of the stem, but larger and often more dentate. Perianth normally oblong, trigono-prismatic, the keels sometimes winged or toothed, mouth not narrowed, trilobate, with the lobes usually toothed. Calyptra free. Capsule longly pedicelled. Androecia intercalary on the stem or long branches, but not unknown on short spicate branches. Perigonial bracts with an inflated antical lobule, antheridia single.

Hep., p. 169; Loph. inalis (Tayl.), ibid, p. 701; Loph. sabuletorum (Hook.), ibid., p. 697; Jung. subintegra Tayl, Lond. Journ of Bot., 1844, p. 477, Lejeunea subintegra (Tayl), Syn. Hep, 376; Loph. subviridis (Tayl.), ibid, p. 699.

Plants small to fairly large, very variable, pale to whitish, sterile stems often, and fertile ones occasionally, with gemmiferous leaves. Stems 1–3 cm., little branched, fertile stems shortened, sometimes with a subfloral innovation, stolons sometimes present bearing curious, remote little leaves with uneven margins and apices. Leaves of fertile stems oblong-ovate to broadly ovate from a broad base, obliquely spreading, apices variable, entire, retuse or more usually bidentate, with lobes short or traingular-acuminate or truncate, or occasionally with a third tooth, convex with margins strongly recurved; leaves of sterile stems very variable, ligulate, rounded or retuse, to broadly ovate, margins often uneven to erose, apices also irregular with protruding cells, apical teeth occasionally even branched. Cells hyaline, as small as 12μ, at the apex of large leaves, usually larger to 30μ on narrower leaves, trigones small. Stipules variable, usually very large on sterile stems, ovate, with apices incurved towards the stems, bifid to ½, segments broad with a small lateral tooth, and apices triangular or triangularacuminate, on fertile stems increasing in size upwards, with the sinus becoming

– 333 –

smaller. Invol. leaves much larger than the cauline, innermost the largest, broadly ovate, convex, shortly bifid, lobes triangular to lanceolate, sometimes crisped. Invol. stipule very large, similar to the leaves, apices often reflexed to cucullate. Perianth large, keels slightly winged, deeply 3-lobed, mouth toothed, sometimes quite jagged. ♂ bracts tightly packed, with basal parts often obscure.

This is a very variable species, but its whitish colour, sometimes gemmiferous leaves, convex, obliquely spreading, together with the generally large, obliquely spreading stipules are characteristic. “An extremely variable plant common in all the Antarctic Islands”, is a note in the Flora Novae Zelandiae.

Chiloscyphus canaliculatus, Syn. Hep, 710, 1847.

Lophocolea canaliculata, Spec. Hep., iii, p. 86, 1909.

Plants medium, dioicous, common, variable, in varying shades of green often drying to whitish, fragrant, forming dense patches on wood, earth, stones or rocks. Stems 1–3 cm., creeping, with numerous rhizoids, branched, branches sometimes short, sub-erect with a tufted effect. Leaves imbricate, sub-alternate to 1.3 mm., ovate to rounded-ovate, apices decurved, obtuse or round, lower leaves usually retuse to shortly bi-lobed, lobes triangular, ventral margin often a little more arched than the dorsal. Stipules connate on one side with leaf, bifid, segments lanceolate-acuminate, sometimes hamate, each with a smaller lateral segment. Cells ca. 20μ with rounded lumen or hexagonal with minute trigones, walls sometimes thickened Invol. leaves mostly entire, uppermost stipule only shortly bifid, with a lateral tooth. Perianth large, firm, triquetrous, mouth 3-lobed, lobes variously irregularly laciniate-toothed. ♂ plants fairly common, bracts terminal in few to many pairs.

Var. crassiflora Pearson is described as having a perianth 3–4 cells thick near the base, and large 6–7 toothed stipules.

It is my considered conclusion that Mitten was right in reducing Lophocolea canaliculata to this species. The thin, narrow perianth drawn by Stephani (who reinstated the species) is on a small stem, but a typical broader one is also present in the packet.

– 335 –

The sometimes convex, dorsal leaf margins, sloping to a decurved, usually entire leaf-apex is the distinguishing characteristic of this species.

Very common in the North Island, and probably in the South, but only a small proportion of the specimens have perianths.

Reported by Stephani to be common in New Zealand, Australia and Tasmania. Type from Swan R., W. Australia, leg. Drummond.

Lophocolea dalliana Steph.

Lophocolea dalliana Steph., Spec. Hep., iii, 85, 1909.

Plants fairly large, pale, soft. Stems to 3 cm., branched a little, or with several branches from the base, suggesting a somewhat tufted habit. Leaves alternate, ovate to broadly ovate, a little imbricate, near 2 mm. long, base ca. 2 mm. broad or a little more, margins entire, dorsal long and sloping, a little decurrent, ventral somewhat arched, apex broadly obtuse; cells 20–25μ at the leaf-apex, basal a little bigger, trigones none. Stipules large, bifid, segments lanceolate, a little diverging, setaceous, connate on one side with leaf, often with 2 smaller lateral segments or spines.

The soft, flaccid leaves with long dorsal margins characterize this species. There are connecting forms between it and L. heterophylloides, of which it might be a form, induced by moist conditions. The Stewart Island plant has some leaves with apices very shortly bidentate, as in L. insularis.

Lophocolea australis (Tayl.) Mitt.

Lophocolea multipenna in part (Tayl.), Syn. Hep, 699, 1847.

Leioscyphus australis Steph., Spec. Hep, iii, 262. 1909.

Plants dioicous, in depressed cushions or creeping through other bryophytes, variable, usually dark brown. Stems to 6 cm, but usually shorter, simple or sparingly branched, flexuous, sometimes with repeated innovations, rhizoids numerous in tufts. Leaves subopposite, imbricate, ovate, usually secund, ventral margin arched, dorsal straighter, apices variable, obtuse or shortly 2–3 toothed, 1.1 mm. long, 1.1 mm. wide at base; cells 30–40μ, large and smaller intermixed, trigones large, acute Stipules bifid to ½ or more, segments with a lateral tooth, connate with leaf on one side and narrowly on the other. Invol. leaves in 3 pairs increasing in size upwards, appressed, entire, the inmost subrotund Invol. stipule bifid to ½, segments with one lateral tooth, parallel or diverging Perianth

– 336 –

variable, normally large, 2 ½-3 mm., flat with the third side narrow and folded in, sometimes cylindrical and chiloscyphold, occasionally lamellate, obscurely 3-lobed, mouth entire or toothed.

The variability of the perianth, perhaps due to the great age of the species, is misleading as to genus, but in the present stage at any rate, it is nearest to Lophocolea. The brown, ovate, generally entire leaves with large cells and trigones will help in its identification. It differs from Chiloscyphus beckettianus (syn. Loph. piliflora St.) in the large cells, and in the stipules being bifid and not conspicuously connate with the leaves.

Loph. multipenna (Tayl.) Syn. Hep. This type now consists of two species, Loph. pallida Mitt. and Loph. australis The Handbook gives the mixture as Leioscyphus chiloscyphoideus and Loph. pallida. Mylia chiloscyphoideus (Ldbg.) Herz. is a South American plant, first described as a Plagiochila. Perhaps the Handbook is not entirely wrong in referring “Lophocolea multipenna” to Leioscyphus chiloscyphoideus. Perhaps our New Zealand and subantarctic plants with their obscurely lophocoloid perianths are either ancrent or advanced forms of this species. We certainly have one specimen (Allison 395) with a flat, compressed, bilipped perianth, which differs in no other visible respect from Loph. australis.

It might be mentioned here that for Lophocolea multipenna Stephani describes the second plant in the mixture, Mitten's Lophocolea pallida.

Loph novae zelandiae (Nees), Syn. Hep., Hodgson, Svensk Bot. Tids., Bd. 42, H.3, 1948.

Plants small, lowly tufted, usually pale to whitish, brownish when dried, mostly sterile, ♂ plants perhaps more common that the ♀. Stems ½-1 cm., filiform, sub-simple, prostrate or decumbent. Leaves alternate, explanate or conniving, oblong-elliptic, to 0 5 mm. long, apices very variable, entire, obtuse, or

– 337 –

retuse, with a shallow sinus to shortly bifid, lobes rounded or obtuse. Stipules free, bifid to the middle, segments narrow, with or without a lateral tooth, apices incurved. Cells 20–30μ, pellucid, trigones small or absent. Invol. leaves larger than the cauline, margins a little undulate, entire or shortly bi-lobed with lobes obtuse, stipule shortly bifid, lobes a little converging, acute. Perianth large for the size of the plant ca. 2 mm., acutely triquetrous, ¼-⅓ tri-lobed, lobes a little undulate, sub-crenate to variously toothed ♂ bracts occupying most of the stem, crowded, entire, reflexed.

Plants often have stolon-like branches on which all the leaves are small and bifid.

There is a fairly common species of Chiloscyphus very similar to Lophocolea calcarea, but a little larger and darker, with leaf-apices more consistently rounded. Fruiting specimens of this plant were discovered by K. W. Allison, Aug. 1947, H1405, and L. J. Jack, Oct. 1950, H5410, at Horse Range, N. of Palmerston (Otago), thus conclusively separating it from L. calcarea.

Occasionally this plant comes very close indeed to Loph. perpusilla (Tayl.).

There is only one species of this little Lophocolea, and Herzog's L. wairoae cannot be maintained.

The contents of Stephani's packet received from Geneva are fragmentary, but consist of two species. the little one which is described, and a much larger one, resembling a form of L. biciliata. His drawing appears to represent the leaves of the larger one with the stipules of the smaller one.

Lophocolea okaritana Steph., Spec. Hep, iii, 85, 1909.

Lophocolea notophylla (Tayl.) Hodgson, Trans. Roy. Soc. N. Z., 78 499, 1950.

Plants pale, straw-coloured or dull green, pulvinate, aquatic and water-worn specimens hard to identify. Stems to 5 cm., mostly simple, but occasionally

– 338 –

fasciculately branched, sometimes flaccid. Leaves imbricate to densely so, obliquely spreading, well rounded, to 1 mm. long, but often shorter, narrowed to the base, sides of leaf normally decurved, making the leaf very convex, entire. Stipules ovate, or rounded ovate, emarginate or slightly truncate with acute angles, often convex like the leaves, very variable in size, from ¼ to almost equalling the leaves, insertion arched. Cells small, rarely more than 20μ, trigones variable, minute to confluent, walls thickened in aquatic forms. Invol. leaves convex, longer than the cauline, upper margins undulate, apex shortly bifid. Stipules narrow ovate, shortly bidentate. Perianth long, strongly 3-keeled, narrowed to the mouth, mouth shortly 3-lobed, lobes variously toothed.

Normally this species is quite distinct with its pale colour, long simple stems, rounded, entire leaves decurved at the sides, and the ovate almost entire stipules. Although there is no specimen of Taylor's type in either the Hooker or Mitten Herbarium, with which to compare the mainland plant, Lophocolea okaritana St., I believe that they are the same specres, especially as Stephani himself identified one gathering of Kirk's from Okarito as Jung. notophylla. Lophocolea otiphylla (Tayl.) from Cape Horn, cannot be far removed from it.

Judging by the drawing in Bastow's Plates of Tasmanian Hepaties, Loph. austrigena (Tayl.) Syn. Hep, of Tasmania, appears to be the same thing.

Leioscyphus stronglyophylla, Handb N.Z. Fl, ii. 508, 1867; Spec Hep., iii, 220, 1909.

Plants minute to small in tufted or closely creeping mats, bright green when fresh, usually in a damp place (local specimens). Stems 0.5–1.5 cm., simple or branched, erect and tufted or procumbent Leaves 0.3–0.9 mm., loosely imbricate to imbricate, entire, subeircular often margined, erecto-patent sometimes secund, mostly coneave Stipules oblong-ovate, bifid, or shortly truncate with the corner angles produced. Cells variable, ca. 20–25μ, appearing large in such small leaves, pellucid or with contents round the walls, walls often thick, sometimes sinuous, trigones small or large. Invol leaves ovate, larger than the caulme, concave, stipules rectangular-oblong. bifid Perianths often with innovations below, cylindrical, sometimes inflated, mouth entire to crenate, 3-lobed, the dorsal ridge showing up plainly ♂ bracts crowded on the upper halves of stems, entire.

The usually small size, round leaves with typical cells and large trigones (as a rule), mark this species. Except for the stipules, sterile stems might be

– 339 –

mistaken for Jungermannia inundata. Lophocolea zotovii differs in the minute cells and practically absent stipules, but there are plants which could be assigned to either species, which is not very satisfactory.

Mitten saw the perianth as 2-lipped, but it may have been pressed into that shape.

Lophocolea turgescens (Tayl.) comb. nov.

Jungermannia turgescens Tayl, Lond. Journ. of Bot, 1844, p. 376; Syn. Hep., 671, 1847.

Leioscyphus turgescens, Handb. N. Z. Fl., ii, 508, 1867; Steph., Spec. Hep., 30, 1909.

Lophocolea crassiretis Herz., Trans. Roy. Soc. N. Z., 65, 354, 1935.

Plants closely creeping on bark, or compactly tufted on earth, golden-brown, shining, small. Stems to 1 cm., prostrate and intermingled or sub-erect, little branched. Leaves alternate, a little imbricate, sub-erect, concave, reniform, nearly twice as broad as long, ca. 0.7 mm. × 0.4 mm., when flattened, restricted at the dorsal base, forming a sinus. Cells ca 20μ, characteristic, with walls greatly thickened, forming large trigones, often confluent, lumina sub-stellate with contents. Stipules variable in shape. free, obovate to sub-quadrate, truncate with corners dentiform, or emarginate to shortly bifid. Invol. leaves larger, entire, stipule entire or crenate. Perianth cylindrical. angles quite obsolete, mouth 3-lobed, entire or a little crenate.

This species agrees in every respect with Leioscyphus turgescens in Herb. Mitten.

The Handbook places this species in the genus Leioscyphus (Mylia), describing the perianth as “truncate, compressed”, while the Synopsis it as “postea cylindrico-compressum” The natural shape is certainly cylindrical, with a 3-lobed mouth, the latter doubtless influencing Herzog to describe it as a Lophocolea, where it appears better suited than in Mylia.

Lophocolea fiordlandiae sp. nov.

Sterilis, parva, pallide-olivaceo-viridis, terricola, depresso-caespitans. Caulis ad 1 cm. longus, ad 0·15 mm. latus, validus, arcte repens, subsimplex, flexuosus, rhizoidibus numerosis. Folia caulina succuba, vix imbricata, oblique secunda, antice decurrentia, oblonga vel ovato-oblonga, 0.5 mm longa, marginibus strictis, interdum parum arcuatis, apicibus variabilis, truncato-lunatis, obtusis vel retusis. Amphigastria bifida ad ca. ½, sinu obtuso, laciniis parum divergentibus incumis saepe desunt vel squamiformia. Cellulae apicales 10μ, basales ad 20μ.

Plants sterile, small, in a depressed mat, pale-olive-green. Stems simple or a little branched, mostly ca 1 cm. long to 0.15 mm. wide, flexuous. intricate, dccumbent, rhizoids numerous. Leaves succubous, mostly and obliquely secund, scarcely imbricate, oblong to oblong-ovate. 0.5 mm. long, margins straight, or a little arched dorsal decurrent. Apices irregular, truncate-lunate, obtuse or retuse. Stipules sometimes well developed, bifid to about ½, sinus obtuse, segments diverging and incurved, slender, but may be absent or very difficult to detect. Cell cavities rounded, clear, all separate, ± in rows. from 10μ in the upper portion of the leaf, as in Plagiochila fuscella, becoming more oblong or quadrate to 20μ, resembling those of a Bazzania.

As there is no sign of any inflorescence in the gathering, it is not certain that this is a Lophocolea, but it is very small for a Chiloscyphus, and does not seem to be a Saccogyna.

Lophocolea zotovii Herz.

Lophocolea zotovii Herz., Trans. Roy. Soc. N.Z., 65, 354. 1935.

Plants in matted tufts, green drying to brown, from wet habitats. Stems ca. 2 cm., suberect, a little branched, stoloniferous, stolons with minute leaves. Leaves remote or a little imbricate, alternate, spreading, to suberect, almost round, very concave, entire, insertion subtransverse. Cells small at apex of leaf, ca. 12μ, larger towards the base. obscure. Stipules mostly absent, or extremely hard to pick up, “parva, appressa, remota, libera, sublinearia, ultra medium bifida, laciniis angustis subsetiformibus, porrectis, sinu angustissime rimaeformi.” Invol. leaves larger. entire. Invol. stipule narrow, oblong, bifid to ½, segments narrow. lanceolate-acuminate. Perianths with a longish neck, faintly 3-keeled, mouth 3-lobed. ♂ bracts in few pairs at or near the apex of the stem.

Though the types of L. zotovii and L. stronglyophylla differ reasonably enough, there are difficult intervening specimens which could be assigned to either.

Lophocolea paucistipula Rodway.

Loph. paucistipula Rod., Papers & Proc. Roy. Soc. Tas., 1916.

Plants erect and densely tufted or more usually sub-aquatic and loosely pulvinate, brownish or dark olive-green to blackish, rarely fruiting. Stems 3–6 cm., simple or a little branched. Leaves to about 1.2 mm., crowded and imbricate in tufted specimens, but usually only sub-remote to a little imbricate, sub-erect or obliquely spreading, rounded, margins entire, sometimes undulate, dorsal a little decurrent, ventral arched at the base, and overlapping the stem. Stipules oblong and shortly bidentate when present, but mostly absent (except in the region of reproduction) or reduced to a small scale. Cells rather opaque, ca. 25μ, rounded-hexagonal, trigones small. Invol. leaves similar to the cauline, but larger and somewhat narrowed to the apex. Invol. stipule narrow-oblong, shortly bidentate, margins often dentate Perianth “narrow campanulate, ½ exserted, trigonous, .. mouth broad with 3 broad unarmed lobes”. In the Maungatua specimen, the perianths are inflated with the mouth a little and bluntly toothed, but in the Atiamuri specimens they are narrowed to the apex with the lobes entire.

This species is distinguishable from L. planiuscula by the general absence of stipules and the ampliate ventral leaf margin. According to Rodway it is allied to Loph. austrigena (Tayl) Syn. Hep., from Tasmania (Rodway), Fuegia and Falkland Is.

No. 5937 from Mokai Patea has stipules either absent, or long and very slender.

Most of the plants now placed here were originally thought to be Jungermannia rotata Tayl. But the discovery of perianths and the examination of Rodway's type show that this is not so.

Lophocolea leucophylla Steph., Spec. Hep, iii, 263, 1909.

Plants dioicous, smallish, pale, often creeping on other bryophytes, variable. Stems 1–2 cm., sometimes a little flexuous, or curved at the apex, somewhat branched. Leaves opposite with dorsal bases in each pair connate, imbricate,

– 342 –

ovate, flat in the type fragment, but more often convex with recurved margins, apex bi-spinose, sinus obtuse of varying width and depth, dorsal margin with 1 or 2 spines, ventral bi- or trispinose, papillae mostly absent. Stipules subquadrate with 4 equal spines, broadly connate with the leaves, usually flat, sometimes subcucullate as in L. Leucophylla. Cells 20–30μ, sometimes reaching 40μ, irregular as to size, trigones also irregular. Perianth barely 2 mm., strongly 3-keeled, keels sparsely spinose, spines from a broad base, as also in the involucral leaves. Stipules with a lateral spine, confluent with the invol. leaves. Androecia intercalary and apical on the stems.

The perianth is described (for the first time) of a specimen from heavy bush, amongst clumps of Schistochila and Leucobryum on forest floor, Waipoua Forest, H744. This specimen also has the dorsal margins multidentate as in L. leucophylla, but the stipules are strongly connate with the leaves on both sides, which seems to me a good distinguishing mark between the species, and Stephani was probably not quite right in making L. aculeata a synonym of L. leucophylla.

Lophocolea muricata (Lehm.), Syn. Hep.

Jungermannia muricata Lehm, Linnaea, iv, p. 363.

Lophocolea muricata, Syn. Hep., 169, 1844; Fl. Nov. Zel., ii, 138, 1855; Handb. N.Z. Fl., ii. 511, 1867; Spec Hep., iii, 116. 1909.

Plants dioicous or monoicous, pale or dull green, often with pale tips, small, occasionally extremely minute, almost always creeping on dead or rotting wood or bark. Stem ½-2 cm., a little branched, with rhizoids and often hard to detach from the substratum. Leaves imbricate, sub-horizontal to obliquely spreading, ca. 0.7 mm., ovate, usually convex with decurved apices, ventral margin usually arched more than the dorsal, apices sub-entire to bidentate, sinus shallow to obtuse; margins and usually both dorsal and ventral surfaces armed on the upper portion at any rate with 2-celled papillae; cells porose, sometimes quadrate. ca. 18–20μ, basal larger with or without trigones. Stipules free on one side, bifid, segments acuminate to setaceous, 2 or more marginal spines, cells more rectangular than those of the leaves and without papillae. Invol. leaves similar to, but not much larger than the cauline, stipule larger, 4-fid. Perianth conspicuous, broadly 3-keeled, sometimes tumid, papillose, mouth 3-lobed, spinulose with marginal papillae. Androecia in few pairs on shortish branches when monoicous, ramose when dioicous.

This species is easy to recognise by its papillose surfaces combined with its small size, but the correct placing of forms intermediate between this and L. villosa is a matter of opinion. Generally speaking, its bifid stipules, flatter leaf-margins and smaller size, will serve to distinguish it from that species.

Plants dioicous, usually whitish, pale brown or straw-coloured, or dingy green, medium to robust, variable, rarely fruiting. Stem from about 3–8 cm., little branched. Leaves imbricate. often crowded and less decurren on shorter stems, papillose, sub-triangular, convex, usually with recurved margins, apex very narrow from a broad base, bidentate, dorsal margin usually toothed towards the base, ventral somewhat undulate, toothed to spinose. Stipules moderately large, quadrate-rounded, strongly decurved to sub-cucullate, multi-toothed or spinose, one side usually free, the other slightly connate with the leaf. Cells ca. 20μ, with one papilla, trigones small, or larger with larger cells. Invol. leaves and stipule large, all confluent. Perianth 5 mm., mouth and keels dentate or spinous-dentate, the third side sometimes folded in, which doubtless explains the Synopsis description of “compresso bilabiato”. ♂ bracts shorter than the leaves, termmal on stem and branches (in plants seen).

In the first of the Synopsis descriptions L. leucophylla is described as having bifid stipules This is doubtless a mistake, as a note by Gottsche, following the second description is to the effect that Taylor had written to say that both the Tasmanian and Auckland Is. plants were the same specres. This was accepted by the authors of the Synopsis, who made the two synonymous.

A specimen from Ligar's Gully, coll. Kirk, 4892, appears to be entirely without papillae. This is unusual.

But Taylor's description in the Flora Antarctica speaks of one, “una”, with this characteristic. I have the following 4 specimens like this, which in addition have entire or subentire leaves. But papillae are mostly present, and the general appearance is that of L. leucophylla.

Lophocolea villosa Mitt. ex Steph.

L. villosa Mitt., Ms., Steph., Spec Hep, vi, 299, 1924.

Plants dioicous, medium to sub-robust, pale, dull green to dingy brown, in flattened loose or compact mats, in the North Island usually under manuka. Stems to 3 cm., branched, sometimes with subfloral innovations. Leaves imbricate, concave, broadly ovate, obliquely spreading ca. 1 mm. long, apices decurved, shortly bidentate, ventral margin arched, margins spinulose, sometimes toothed as well; dorsal surfaces papillose, ventral less so. Cells ca. 20–25μ, mostly with a single high papilla. Stipules wide, free or slightly connate with the leaf on one side, 4-fid, the lateral segments smaller, the middle ones finely acuminate, basal portion sparsely papillose, margins all spinulose. Invol. leaves large, sub-circular, very concave, margins and bidentate apices everywhere irregularly toothed and spinulose. Perianth soft, sparsely papillose, 2 ½ mm. long × 2 mm broad, keels irregularly toothed, mouth deeply 3-lobed, margins of lobes irregularly laceratetoothed. ♂ bracts in pairs, terminal on stems.

This species differs from L. muricata in its larger size and 4-fid stipules, and perhaps more concave leaves and flattened, broad perianth. Viewed dorsally, with its bidentate apices decurved and hidden, it has the appearance of a papillose L. heterophylloides.

L. cinerea Herz. from dead wood in bush, Terapatiki, near Waikaremoana, 297, E. A. H., is a form with shorter, more compact branches, with more crowded leaves, and papillae less frequent in places I really do not think it is distinet enough to be a separate species.

Lophocolea variabilis Steph.

Lophocolea variabilis Steph., Spec. Hep., iii, 110, 1909.

This species much resembles L. heterophylloides in habit and appearance, but differs in the irregular leaf-apices, and in the leaf margins being shortly, sometimes sparsely toothed; also in the occasional presence of papillae, showing an affinity with L. villosa. There are intermediate forms between L. insularis and this species.

Lophocolca trialata, G., Spec. Hep., iii, 92 (as regards N. Z.), 1909.

Plants polyoicous, often pale, sprawly, usually on rotting wood or tree-fern bases. Stems elongate to 4 cm., when sterile, intricately branched when fertile, with an innovation below the perianth. Leaves opposite, contiguous to densely imbricate, plano-distichous to obliquely spreading with the upper ones convex, broadly triangular-ovate to oblong-ovate, margins sub-straight, apex of varying width, ⅕ to ⅓ the width of the base, variable, but mostly obliquely truncate and bidentate, the ventral tooth usually bigger than the dorsal, sometimes entire, obtuse or acute. Stipules connate with the leaves, bifid with 2 lateral segments, sinus shallow. Cells 30–40μ, with contents adhering to the walls, otherwise pellucid, trigones present, sometimes confluent. Invol. leaves increasing in size upwards, conforming with the cauline, but with the ventral margin incurved, thus appearing more narrowly triangular in proportion to the size. Invol. stipules usually connate with the leaves, ovate, ¼-⅓ bifid, segments sparsely toothed. Perianth narrow-oblong, tapering to the mouth, to 5 mm. long, triquetrous or 3-winged, wings strongly toothed to crenate. Mouth 3-lobed, irregularly and strongly spinous-toothed, apical spines longer Androecia on special branches or terminal on otherwise leafy branches, bracts oblong, erect to spreading-decurved, shortly bidentate.

The triangular-ovate, opposite, often crowded leaves, with connate stipules, are the characterstic of this species, together with the tapering perianth appearing lateral as well as terminal, and the ofttimes monoicous inflorescence.

Lophocolea fulva Steph.

Lophocolea fulva Steph., Spec. Hep., vi, 273, 1924.

Plants small, sterile, yellow-brown. Stems 1 cm. or a little more, a little branched. Leaves crowded, obliquely spreading, ca. 1 mm. long, but some stems have smaller leaves, broadly triangular with an occasional ventral tooth, base ca. 1 mm broad, apex narrow, bicuspidate. Stipules rounded with 3 or 4 usually small teeth, so broadly connate as to be all in one with the leaves, with an intervening undulation or fold. Apical cells irregular, ca. 20μ, gradually increasing to the base, trigones also variable, acute, cuticle smooth.

There is a plant from Campbell Is., leg. J. H. Sorensen, 3407 Herb. E. A. H., which, in its rounded, broadly connate, shortly toothed stipules, suggests L. fulva, but in other respects, including size, it resembles L. leucophylla. This may represent an undescribed, new species.

The type is presumably from Auckland Is., leg. Cockayne, of which there is a duplicate in the Auckland Muscum, so identified by Stephani. In Species Hepaticarum, Stephani gives Australia also as a locality and mentions it first.

Plants medium, dioicous, whitish or pale green, rarely pale brown, loosely intricate. Stems to about 3 cm; prostrate, somewhat curved at apex, little branched, canaliculate. Leaves opposite, densely crowded, crecto-patent, convex with recurved margins. oblong-ovate, apex decurved, narrow, biciliate with an obtuse, sometime deep sinus, margins entire except for an occasional ventral tooth, dorsal decurrent. Stipules very wide, reniform with 6 triangular spinose lobes. Cells pellucid, ca. 30μ, trigones medium, no papillae. Invol. leaves dentateciliate, specially on the ventral margin, stipules taller than broad, apex and

– 347 –

upper half of margins spinose-ciliate. Perianth 4 mm., deeply keeled, mouth dentate-lacerate. ♂ bracts to 20 pairs, squarrose, acute or bidentate.

This species can be recognized by its very broad triangular-lobed stipules and densely crowded bicilate leaves.

Lophocolea innovata Hodgson sp nov.

Planta parva, nitida, dense caespitosa, fusca. Caulis ad 1 cm., cum brevibus sub-flore saepe repetitis innovationibus Folia caulina parum imbricata, recta patula ca. 1 mm., ovato-quadrata, bi- aliquando tri-lobata, lobis triangularibus, acutis vel obtusis, tertio minore vel solum dente, marginibus curvato, praecipue ventralo Amphigrastria libera, profunde bifida, segmentis lanceolatis, divergentibus, sinu lunato Cellulae 30–40μ, trigonis nullis. Folia floralia majora, subrotundata, marginibus grosse dentatis, amphigastria anguste oblongo-ovata, parvo laterale dente, breve bifido, sinu obtuso, laciniis triangularibus. Perianthia parva, subcampanulata, trilobata, emersa, marginibus dentatis.

Plants small, brown, shining or spotted, densely tufted, perianths upright, plentiful Stems to 1 cm., with numerous short sub-floral innovations (hence the name). Leaves ca. 1 mm, ovate-quadrate with the ventral margin more arched than the dorsal, apices bilobed, sometimes with a smaller lobe or tooth, on the ventral margin near to the extremity of the leaf, occasionally retuse, lobes triangular, usually about equal in size, acute or rarely obtuse. Stipules free, deeply bifid, segments lanceolate, diverging, sinus obtuse to lunate. Cells 30–40μ with contents adhering to thick walls. Invol. leaves larger rounder, in several pairs enveloping the perianth, margins ± dentate. Invol. stipule narrow oblong-ovate with a very small lateral tooth, bifid to about ⅓, segments straight or divaricating, triangular. Perianth small, emersed, with only undeveloped archegonia, subcampanulate, faintly 3-angled, 3-lobed, sometimes deeply, lobes with toothed margins. Androecia not seen.

The shiny, 2-lobed (rarely 3-lobed) leaves make this species easy of recognition except for a certain resemblance to Chiloscyphus triacanthus, but that species has longer leaves and the apical appendages longer and more slender. I am indebted to Mr. Allison for pointing out that the perianths are not truly lateral,

– 348 –

but have innovations arising from the vicinity of the involucral stipule, sometimes from the axil itself.

Lophocolea amplectens Mitt.

Lophocolea amplectens Mitt., Fl. Tas., ii, 226, 1860; Steph., Spec. Hep, iii, 57, 1909: Rod., Papers & Proc. Roy. Soc. Tas., 1916.

Plants small, closely matted, light brown Stems mostly less than 1 cm., little branched except for innovations, procumbent. Leaves varying in size on different stems, scarcely imbricate, set at an acute angle on the stem, insertion almost transverse, concave to conduplicate, slightly incurved, 0·3–0.5 mm., ca. ⅓ bilobed, lobes broadly triangular, subacute, sinus broad, obtuse to deeply lunate. Stipules smallish, slightly connate on one side, ca. ⅔ bilobed, lobes narrow-triangular, with a lateral tooth on stems with larger leaves, more slender where the leaves are small. Cells 20–25μ, cavities rounded, marginal row slightly larger, trigones present and distinct. Invol. leaves and stipules all closely imbricate as in L. bispinosa, and deeply cleft with narrow lanceolate lobes, with margins sometimes recurved. Perianths sometimes with several and repeated innovations, small, only 1 mm. in length, 3-angled with one or two intermediary ridges, mouth irregularly dentate.

This species differs from L. bispinosa in the erecto-patent, concave, sometimes conduplicate leaves, with ± transverse insertion, and obtuse to sub-acute apices of the lobes. There are 3 gatherings of this Tasmanian species not previously reported from New Zealand. They are, on ground, near Hermitage, Mt. Cook, 492, G. O. K. S., Jan. 1934; shady bank overhung by tussocks on south side of ridge, Silver Peak Range, ca. 2.000 ft., 29/12/47, H1413, on bare rock, sheltered by tussock, on slope of Flagstaff Hill, Dunedin, ca. 1,800 ft, H5200, 21/1/50, K. W. A. I also have it in a manuscript list of hepatics collected by the Cape Expedition in the subantarctic islands, but have no duplicate with which to check it, but I think it would be correct.

The type was from Tasmania.

An additional locality is, among stones, head of Hollyford R., 2,000 ft, Doubtful Sd., Feb. 1951, W. M. (6705).

– 349 –

Plants common, small, pale to hyaline, loosely caespitose, often mixed with other bryophytes on banks, in grass, etc., extremely variable. Stems filiform, fertile ones erect or ascending, microphyllous branches with remote bifid leaves very often present, 1–2 cm. Leaves sub-remote or loosely spreading, but on some stems closely imbricate and erecto-patent, plane or convex, ovate-oblong to rectangular, 1 ½ to twice as long as broad, ⅓–½ bifid, not, or rarely, narrowed at the apex, apex truncate-emarginate, sinus lunate or angular, lobes from a triangular base, acuminate to longly and narrowly so, often diverging; margins fairly parallel, but the ventral may be somewhat arched, dorsal sometimes a little decurrent, as in the type. Stipules free, spreading, often incurved, usually 4-fid, with the exterior segments smaller and spiniform, the middle ones longer and narrow-lanceolate. Cells very variable ca. 18–25μ, obscure or pellucid, with rounded cavities and sub-confluent trigones, or sub-quadrate with small trigones, marginal row often considerably larger. Invol. leaves in 2–3 pairs, increasing in size upwards, convex, crowded in a dense head, the innermost pair deeply bifid, segments linear, setaceous, prettily curved, margins entire or dentate. Stipules quadri-laciniate with apices longly setaceous. Perianth shortish, narrow, triquetrous, shortly tri-lobed, lobes irregularly laciniate. ♂ bracts erecto-patent, crowded on the upper half of the stems, bispinose and little different from the lower leaves.

Loph. perpusilla, reduced to this species by Mitten, is a tiny plant, with the corner angles of the leaves shortly produced or truncate.

Loph. mittenii is the form common on the mainland, with leaf-segments more longly produced than in the type.

Loph. curvifolia is very small, so called because the lower basal margin is incurved as in Loph. inflexifolia.

Loph. minuta is a small form with narrowish, deeply bifid leaves with a rounded sinus.

I do not find it possible to fit into the descriptions of these “species” the many varied forms of this complex group. For instance:

No. 3464, from Waikaremoana, has very large stipules, oblique and recurved as in Loph. novae zelandiae, with narrowish, deeply bifid leaves with segments converging, while leaves on other stems match Taylor's type very well.

No. 3512, from Wilkin R., Otago, coll. G. Simpson, has the leaf and stipule segments exceedingly longly tapering and spiniform.

No. 1617, from Milford Track, coll. F. MacDonald, has all the margins finely recurved.

The incurving of the ventral margin is very noticeable in a larger, very spiniferous specimen with minute cells from Mt. Maungatua, 5256, W. Martin.

None of the published descriptions mentions the marginal row of enlarged cells which is so often present, though hardly so in Taylor's plant.

The type was from Campbell Island, collected by Hooker.

Lophocolea subporosa Mitt.

Loph. subporosa Mitt., Fl. Nov. Zel., ii, 137, 1855; Hook. f. Handb. N.Z. Fl., ii. 509, 1867. Spec. Hep, iii, 97, 1909.

Plants small, dull green, creeping on wood, or forming loose mats on earth. Stems 2–3 cm., subsimple or well branched. Leaves imbricate, alternate. ca. 1 mm.

– 350 –

long including the laciniae, and ca. 0.9 mm. broad, broadly ovate to sub-rotund, narrower on the branches (in the type). Margins arched, dorsal a little less than the ventral and a little decurrent; apex bidentate, sinus lunate, laciniae rather abruptly narrowed from a broad triangular base. Stipules small to medium, 4-fid, the 2 middle segments longer and wider, free on one side. “Perianthio prismatico, anguli dorsali alato, ala denticulata, ore laciniis obtusiusculis integris denticulatis, foliis involucralibus conformibus, parum latioribus, margine dorsali ventralique parce dentatis, amphigastrio subelliptico bidentato, lateribus remotiuscule dentatis, basi angustate coalito.”

In describing this species, Mitten adds the following note: “Near as this small species unquestionably is to Loph. diademata (= Loph. lenta), in size and habit, it appears to differ in its thicker and more rigid texture, its wider and less deeply emarginate leaves and in the undivided and obtuse laciniae of the perianth.” The trouble is, however, that it is quite within the ambit of the versatile Loph. lenta to show rounded leaves with others not so rounded, and identification then becomes purely a matter of opinion. However, there are plants with the majority of the leaves very broadly ovate, excluded from Loph. insularis by their small size and plane dorsal margins, which could, I think, be called Loph. subporosa. One from Huka Falls (Taupo). 3437, coll. H. M. H., has very rounded leaves with the apical teeth broadly acute, and small cells. No. 57247 from The Snares, coll. F. Newcombe, has the laciniae obtuse with a shallow sinus, and is quite distinct from the stems of Loph lenta with narrower leaves and attenuated laciniae, also present in the tuft.

The type was collected by Dr. Sinclair.

Lophocolea insularis Steph.

Loph. insularis Steph., Spec. Hep., in, 105, 1909.

This species appears to be closely related to L. heterophylloides, differing in the apices of the leaves, which instead of being obtusely rounded are irregular in shape, but mostly with short triangular lobes separated by a ± lunate sinus. It has the same appearance and habit of growth of L. heterophylloides and is likely to be passed over as that species.

Plants common, small, variable, yellowish or dull green, mainly creeping on logs and bases of trees, but also terrestrial, forming loose or compact mats Stems to 3 cm., but usually shorter, specially if fertile, subsimple to intricately branched,

– 351 –

rhizoids often plentiful. Leaves imbricate, bidentate, oblong, oblong-ovate to broadly ovate, or oblong-triangular, plano-distichous or dorsally secund, to 1 mm. long, including the laciniae, margins straight or a little arched, dorsal a little decurrent; apex bidentate, lobes triangular-lanceolate, acuminate, usually parallel, sinus rounded. Stipules simply bifid as in the type, or with a lateral tooth, bifid from about ½–¾, segments lanceolate-acuminate, diverging. Cells 30–40μ, walls thick, trigones very small or absent. Invol. leaves longer than the cauline, concave, oblique, bifid, segments triangular-acuminate, margins usually entire. Invol stipule ovate to elliptic, deeply bifid, segments narrow, usually a lateral tooth present. Perianth oblong-prismatic, well exserted, triquetrous to 3-keeled or winged, keels usually toothed, deeply 3-lobed, lobes longly toothed, apices bifid, segments narrow, setaceous. ♂ bracts crowded, bifid or entire, sometimes merging from one to the other on the same stem, pairs numerous, usually squarrose.

Loph. perpusilla (Tayl.) Syn. Hep. is a diminutive form, having stolon-like stems with tiny bifid leaves mixed with the others. Many of the leaf-segments are obtuse, the cells large. A compact mat of this form, and whitish, No. 4392, similar to Taylor's, was collected on Campbell Island by R. L. Oliver, of the “Cape Expedition”, but one occasionally meets with this diminutive form mixed with ordinary stems of L. lenta. Mitten reduced it to Loph. bispinosa, but stated elsewhere in the Flora Novae Zelandiae that perhaps it might be added to L. diademata and Loph. secundifolia as a synonym of L. lenta. This I have now done.

Leaves on the main stems often approach those of Loph. bidentata.

Loph. beckettiana St., Spec. Hep., vi, p. 263, is probably this species, but the packet thus labelled contains a pure clump of Lepidozia gottscheana.

A common species in both islands.

The type was from Auckland Is., coll. Hooker, but as mentioned by Stephani, the stems are etiolated and elongate.

Leaves imbricate, oblong-triangular, dorsally secund, complicate, abruptly widened at the base and longly decurrent, apices bifid to about ⅓, laciniae narrowly triangular-acuminate, curved, conniving, sometimes forming almost a circle with the sinus. Stipules bifid to the middle, shortly connate with the leaf on one side, segments narrowly triangular, basal portion sub-entire Cell cavities to 35μ, trigones small ♂ bracts in few pairs at the ends of the stems; antheridia large to 0.2 mm. in diameter.

I have no perianths to describe.

This species is nearest to Loph. lenta, differing mainly in the much widened and longly decurrent leaf-base, 1.1 mm. wide according to Herzog's measurement But the great difficulty is to separate the dorsal faces and make the leaves lie explanate, so that one can see these antical bases. In the Arthur's Pass specimen the sudden downward bend of the dorsal margin is even more marked than in the type, and the leaf-laciniae are longer.

There are, of course, connecting forms between this and Loph. lenta.

Lophocolea helmsiana Steph.

L. helmsiana Steph., Spec. Hep., iii, 94, 1909.

Plants olive to yellowish-green, often shiny, mostly on tree-ferns and rotting wood. Stem seldom more than 2 cm., variously branched, often with a sub-floral innovation. Leaves opposite, a little imbricate, ca. 1 ½ mm. long, base about 2 ½ times as wide as apex, margins incurved but unevenly, giving the leaves a twisted look, but fairly straight when flattened. Apex bispinose, sub-truncate, lobes unequal, the dorsal one the smaller, longly acuminate, sinus widely lunate to sub-acute. Stipules small, connate with leaves, sometimes more narrowly on one side, rarely free, bifid to below the middle, sinus acute, segments longly acuminate, with or without a lateral tooth. Cells rather less than 30μ, thickish or with contents round the walls. Invol. leaves a little longer than the cauline, shortly bifid, segments longly acuminate, sinus narrow, dorsal margin unidentate, ventral with few or many spinous teeth. Stipule about half the size of the leaves, broadly ovate, shortly bifid, bis-bifid or margins plurispinose, usually connate on both sides with leaves. Perianth ca. 2 mm., terminal on both branches and stems, deeply 3-lobed, apices of lobes narrowly bifid, margins variously spinoselacinulate.

This is a good species with its oblong-triangular leaves, narrower than in L. pallida with cells less pellucid and stipules smaller, but, even so, one is sometimes puzzled by near resemblances.

The type was from the South Island, coll. Helms.

Var. subparallela var. nov.

Caulis ad 4 cm., simplex vel parum ramosus Folia sub-recte-patula, vix contigua, 1·35 mm. longa × 0.5 mm. lata, marginibus subparallelis, laciniis triangulare-setaceis, sinu profunde lunato. Amphigastria ad 0.8 mm. longa, apice ad ⅔ emarginato-bispinosa, utrinque anguste coalita, spinis divergentibus.

If this is not a separate species, then it is to Loph. helmsiana that it appears to belong, but its narrow leaves, mostly all separate, and nearly at right angles to the stem, give it an individuality that is at once noticeable.

The type is in Kirk's collection, from Thames, No. 6017, Bot. Div. Herb. Other specimens are: On Trichomanes frond with Radula levieri, shady stream bank, Waipoua Forest, H670 p.p., 10/4/44; sandy and shady creek bank in Waipoua Forest, 5573, K. W. A., 23/11/44.

Loph. lamellicalyx Herzog, ibid., p. 351.

Loph. multialata Herzog, ibid., p. 351.

Plants variable, common, often sterile, mostly large, in depressed mats on earth or rotting logs, often glistening. Stems to 3 cm., simple or branched, branches often with smaller and narrower leaves. Leaves contiguous to closely imbricate, alternate to sub-opposite, large to 2 mm. long, broadly ovate to sub-circular, apex shortly bifid, but sometimes rounded and entire, sinus shallow of varying widths, teeth ciliform, but sometimes much shorter; ventral margin usually strongly arched, dorsal usually fairly straight. Stipules free or connate on one side, rarely on both sides, bifid, segments lanceolate, sometimes setaceous, diverging, with a basal lateral tooth, small in comparison with the leaves. Cells 30–45μ, pellucid, trigones small to medium. Invol. leaves, more or less conforming with the leaves, but larger, sub-circular, shortly bifid to sub-entire. Perianth to very large, maybe to 6 mm., 3-winged, usually with lamellae between the wings, the third side may be narrower and folded in, 3-lobed, mouth sub-entire to strongly toothed.

This species varies considerably in appearance, but generally speaking it can be recognized by the very broad, often glistening leaves, and, of course, by the lamellate perianth when this present.

In Loph aucklandica the leaves are crowded, while in L. lamellicalyx, besides being crowded, they are described as “late ovata, brevissime bifida”. In L. multialata, the leaves are opposite, and in L. subscorpionifolia they are described as “laxe imbricata” and “subrectangulari-ovata”. In another form from Caswell Sound area, coll. V. D. Zotov, 5326, the apical teeth are short and very close together on some of the leaves. In a specimen from Banks Peninsula, H. M. H., 4325, the perianths are smooth, while at Atiamuri gathering, coll. K. W. A., H3581, has perianths both smooth and lamellate. Other specimens have many of the leaves entire. To try to maintain these and other forms, even as varieties, leads to confusion.

Mitten who correctly removed sterile plants from Chiloscyphus to Lophocolea, helpfully comments as follows in the Flora Novae Zelandiae: “.. It approaches in size the larger forms of L. bidentata, but has wider leaves with more ciliiform teeth, and a thinner more vitreous (glassy) texture. More perfect specimens of this plant would probably exhibit the stipule combined on both sides with the subjacent leaves …”

I find that this species is liable at times to be confused with Chiloscyphus allodontus. Stephani and Rodway appear to have confused it with the large soft form of Chiloscyphus coalitus.

My specimens from all parts of the North Island number nearly 100; from the South Island, the localities are as follows, with some characteristic habitats.

Waitati, 5089, K. W. A.; logs in bush near Riverton rocks, 5542, W. M.; Campbell Is., 3415, J. H. Sorensen.

The type was from New Zealand, the collector not stated.

Lophocolea inflexifolia Steph.

Lophocolea inflexifolia Steph., Spec. Hep., vi, 248, 1924.

Plants sterile, medium to large, usually pale sub-hyaline, soft. Stem to 3 cm. (Stephani gives 6), simple or with few, long branches, some with larger leaves than others. Leaves a little imbricate, horizontally spreading, with the ventral margin folded over at the base, arched a little, dorsal margin long, sloping; ca. 1.4 mm, excluding the apical setas, base ca. 1·4 mm. wide, excluding the folded-in portion, apex ¼–⅓ the basal width, sinus sublunate, laciniae acuminate, attenuated, parallel, converging or diverging. Cells small, 20μ, interspersed with somewhat larger ones, basal larger. Stipules large, bifid, segments broad, lacerate, setaceous.

Not one of the commoner species, but can be recognized by its inflexed ventral margin, rhomboid leaves with small cells, and large lacerate stipules, though strange to say, the Marlborough plant has small stipules. Though nearest to L. bidentata in appearance, the inflexed basal ventral margin is reminiscent of some forms of L. bispinosa.

Loph. fusca Steph., Spec. Hep., ii, 97, 1909.

Loph. scorpionifolia Steph. Spec. Hep., iii, 108, 1909.

Plants monoicous, robust, pale or brownish, loosely to intricately caespitose, or straggly, very often in grass, or under fern and scrub, cosmopolitan. Stems to 4 cm., much branched, with branches of varying length. Leaves distant to imbricate, whitish, ca. 1.2 mm. long, excluding the laciniae, asymmetric, obliquely

– 355 –

ovate with a long insertion, ventral margin arched, dorsal long, straight or with an inward curve; apex truncate or with a lunate, or more rarely bluntly angled, sinus, ca. ½–⅓ the width of the base, laciniae somewhat abruptly narrowed, subsetaceous. Stipules varying in size, free on one side, 4-fid, the middle sinus as broad or broader than the stem, the middle segments straight, attenuated and spiniform, the lateral smaller but spiniform Cells rounded-hexagonal, pellucid, sometimes with chlorophyll round the walls, 25–35μ (in L. fusca), trigones wanting or small. Invol. leaves erect and convex, otherwise differing little from the cauline Perianth often appearing lateral owing to innovations, large to 4 ½ mm. long, triangular-prismatic, deeply 3-lobed, apex of lobes coarsely spinousdentate, margins dentate ♂ bracts sub-erect on branches, often terminal, in few or many pairs, smaller than the cauline leaves, antheridia appear to be not always present.

It appears to have been Mitten who first recognized Taylor's sub-antarctic and New Zealand species as L. bidentata. Stephani does not record it from New Zealand, but comparisons have been made, and Mitten's determination appears satisfactory. Moreover, the late Mr. W. E. Nicholson did not dispute it. The European state, however, is dioicous, but a smaller, closely allied plant called Lophocolea cuspidata or sometimes var cuspidata is monoicous. One cannot be sure that all our fertile plants are monoicous, but the majority of them definitely are.

In the Dunedin plants, an apical tooth on some of the leaves is obsolete.

A world-wide species.

Additional Notes

Four species of Stephani's not already mentioned are L. cheesemanu, L. kaalaasu, L. petriana, and L. zurnii

The packet of L. cheesemanii seen was from Herb. Beckett, 255, and may not have been Stephani's type It is a very small bidentate specimen. Stephani's drawing of L. cheesemanu shows the perianth with very broad, strongly toothed wings. This is sometimes seen in L. lenta

The packet labelled L. kaalaasii was Kirk's No 440 It is similar to L. grandistipula Schiff. and L. kirku St, varietal forms of L. novae-zelandiae. It is doubtful if this is the type.

– 356 –

The packet of L. petriana was collected by Petrie, 1898, and probably is the type. A very likely identification of this is L. subporosa Mitt.

L. zurnii was not seen. From the drawing and description one concludes that it is L. helmsiana, with stipule segments having a lateral tooth.

A curious little plant which appears to be a Lophocolea was collected on Olearia lacunosa, slopes of Mt. Alpha, 3,900 ft., Tararuas, by A. P. Druce, Jan. 1948 (7047). It is extremely minute, with leaves 0 1–0·15 mm. long, and with terminal capitate strings of gemmae. It is faintly suggestive of L. bispinosa.

Further Notes on Chiloscyphus

I am thankful to have this opportunity to correct and amend as follows the paper on Chiloscyphus, Trans. Roy. Soc. N.Z., 1944, pp. 27–52, written during the war when types were not available.

In Hepaticae Species Novae, 1885–1896, Stephani states that Chiloscyphus oblongifolius (Tayl.), Syn. Hep., is a form of Chilo. coalitus. I now have reason to believe that is correct. It is certainly very similar to Chiloscyphus colensoi Mitt., which I treated as a synonym, but it has the stipules connate to the leaves on both sides as in C. coalitus. I regret this mistake, and am very pleased to re-install Mitten's Chiloscyphus colensoi.

Chiloscyphus chlorophyllus (Tayl.) St., C. menziesii Mitt., C. bidentatus St.

With many more specimens to hand, there is now no doubt in my mind that these three are one and the same species, as was formerly suspected, and in future will be referred to as C. chlorophyllus.

Chiloscyphus normalis (Steph.) Hodgson.

Types from Stephani's Herbarium show that Chiloscyphus beckettianus, Lophocolea piliflora, and Lophocolea normalis are all the same species. As it was therefore not correct to apply Stephani's name of Lophocolea normalis to a certain species of Chiloscyphus, I would suggest now that the name of Chiloscyphus normalis, which is quite suitable (meaning, set at right angles) be retained for the species described under that name, p. 34, but that the reference be changed from C. normalis (St.) Hodgson to C. normalis Hodgson.

Chiloscyphus retusatus (Tayl.) Syn. Hep.

Mention of this species was formerly omitted. According to the Synopsis, it was from New Zealand, but there is no specimen at Kew, and the fragment from Mitten's collection was labelled as from Falkland Is. The Handbook places it in Leioscyphus (Mylia). The Synopsis description points to it being the species now known as Chiloscyphus compactus, but without Taylor's original specimen nothing can be done about it.

Chiloscyphus argutus Nees.

This, a common species in the South Pacific Islands, was collected from Raoul Is., Kermadecs, by A. C. S. Wright (1949), Nos. 67002, 67006, 67008, 67009, Bot. Div. Herb. I have as yet seen no specimen from the mainland, though Stephani gives sub-tropical New Zealand as a locality.

Additional localities for species are as follows:

C. multispinus Hodgson and Allison : Little Akatarawa V., 751, H. M. H. (1945); Steep gully side under manuka, near Herbert, North Otago, H5371, K. W. A. (1950); Auckland Island, “Cape Expedition”.

C. cuneistipulus St.: Auckland Islands, “Cape Expedition”.

C. compactus Col.: On earth, Three Kings Islands, 5563, M. Holdsworth (1951); turf, Great Is., Three Kings, E. G. Turbott, 22011, Auckland Museum (1946); Campbell Is., 3408, J. H. Sorensen (1946).

C. polycladus Mitt.: Auckland Islands, G. Einar Du Rietz (1927).

The following New Zealand species of Chiloscyphus were included in Heteroscyphus, a genus published by Schiffner for species of Chiloscyphus having small perigonial bracts with antheridia on short branches, instead of normally sized bracts intercalary on main stems and branches: C. colensoi, C. coalitus, C. cuneistipulus, C. fissistipus, C. triacanthus, C. chlorophyllus, with C. sinuosus and C. billardieri as probabilities. As already pointed out, Heteroscyphus cannot be maintained in New Zealand, because there are numerous instances in which the androecia are exhibited in both forms in the one species, though this is not allowed for in Corda's original definition of the genus Chiloscyphus.
