Art. XXXIV.A Description of some newly-discovered Cryptogamic Plants, being a further Contribution towards the making known the Botany of New Zealand.*

[Read before the Hawke's Bay Philosophical Institute, 11th October, 1886.]

Introduction.

On this occasion, the last night of ordinary meeting of our Society for this year, I am again permitted to bring you our usual annual botanical offering, in a small basket of Crytogamic plants obtained from our inland woods and glens.

I have called it “our” offering; and this may require a few words in explanation. This plural pronoun is here used in a double sense: (1) To let you know that I have again been largely assisted by kind and liberal, hearty and active, coworkers in this part of the botanical field, who all work con amore in this matter: among them I would particularly mention with thanks three of our active members—Messrs. H. Hill, A. Hamilton, and D. P. Balfour—to whom not only myself and our local branch auxiliary Society, but the New Zealand Institute as a scientific body, are largely indebted. And (2) that this offering or tribute is one made by, as well as from, our New Zealand woods. For, privileged as I am to present and make known this, their free gift, and thus for a short time briefly occupying the position of their herald or ambassador unto you—coming hither directly from them, and from long and oft-repeated sojournings in their homes and company, and understanding their thoughts and quiet reasonings, and silent yet the more expressive language—I would beg permission to say a few words respecting them.

Among the many and varied congenial homes of the great Crytogamic family, in those deeply secluded glens and mountain woods, far away from the busy life of towns, and even the solitary haunts of the isolated “bush” woodman, is the place par excellence for the disciple of Nature to study, to admire, to learn, to know; and so learning, so knowing, to hold converse with her and her beauties; and, through their teachings, with

the one Great Mind and Author of all I One of our esteemed British classical poets, Thomson, in writing on this subject, has truly said,—

“Here wandering oft,
I solitary court
Th' inspiring scene: and meditate the book
Of Nature ever open.”

For (as I have said to you on a former occasion) I believe in the universal language of Nature: and it is with feelings such as those that I have not unfrequently detected new and hitherto hidden and unknown novelties; and when thankfully gathering them have sometimes said, solus, or spoken out to them: “Come out of your obscurity, and be seen in society. Come and be introduced to science. Come and add your tribute also, however small, to the further display of the many great and wonderful perfections of Nature; and, in so doing, more openly fulfil the imperative injunction made to you two thousand years ago, in the words of that very ancient song: ‘Benedicite universa germinantia in terra Domino; laudate et superexaltate eum in sæcula.”‘And then, at such times, I have further thought: How many thousands of years—may be, myriads of ages—since this wee little wondrous delicate and frail yet perfect form first appeared, whether created or evolved; and how, in spite of all opposing and powerful elemental influences, and cataclysms, and volcanic eruptions, has this little microscopical plant held its own, fructifying, and shedding its tiny seeds in their proper season, and so overcoming and riding triumphant over all opposition and every adverse power? Moreover, when I have also occasionally found a little Cryptogam which I knew to be also a denizen of another part of the globe—it may be of the Antarctic islets furthest South, or of Tasmania, or Australia, or the Islands of Polynesia; or of the far-off specks in the vast Southern Ocean, the Crozets, or Kerguelen's Land; of the Cape of Good Hope, or Cape Horn; of the Peruvian Andes, or of the European Alps; of the riparian banks of the Amazon, the Thames, the Tweed, or the Shannon; of the summits of our own Ruahine Mountains, or of the Scottish Highlands—what a further theme for thought! Where the commencement, the outset, the Alpha, the origin? or were there originally more than one such? And, if so, did such embryos, situated at the antipodes of each other, commence life together?

Possibly, or rather very likely, some of the younger portion of my audience here this evening may think these remarks of mine strange, aberrant, or at all events peculiar; pertaining, it may also be thought, to the garrulity of old age, and following as a fitting sequence to my expressed belief in the universal language of Nature. To all such, (if there be any), I would merely reply that thoughts like those I have touched on are (1)

– 273 –

not unreasonable; (2) are eminently pleasing, illuminating, and informing; (3) are qualified to raise our human nature; and (4) to lead us on to more correct views of the Great Father and Author of all. Once more will I quote a few highly expressive lines from my favourite poet Thomson:—

“Nature, attend! join every living soul,
Beneath the spacious temple of the sky,
In adoration join; and ardent raise
One general song—to Him!
Soft-roll your incense, herbs, and fruits, and flowers,
In mingled clouds to Him, whose sun exalts,
Whose breath perfumes you, and whose pencil paints.”

But to leave the mountain-tops, first gilded by the sun, and the purer air of the balmy pine forests and heights, not to mention their kindred poetical musings, and to descend to the plains—to the technical and prosaic facts and descriptions of our few little Crypts.—I have to observe that four of the orders of the great Linnæan class Cryptogamia are here represented—viz., Filices, Lycopods, Musci, and Hepaticæ. Of the first order, or ferns, I have only one novelty, a species of Lomaria; of the second, or Lycopodium, I have also but one new species; of the third, or mosses, I have five new species, belonging to three genera—viz., Polytrichum, Hypopterygium, and Hookeria, all fine mosses and well represented here in New Zealand; and of the fourth, or liverworts, I have 40 species, pertaining to no less than 11 genera, some of which, as Jungermannia, Plagiochila, Mastigobryum, and Frullania, were already remarkably large and cosmopolite. In the “Synopsis Hepaticarum,” published 40 years ago, Plagiochila possess 189 species, Jungermannia 195 species, Mastigobryum 64 species, and Frullania 155 species; and these large numbers of species have been subsequently increased with many more; indeed, out of this present small collection there are no less than 5 species of Plagiochila, 16 species of Mastigobryum, and 6 species of Frullania; while others of those smaller and rarer genera now added to by me are still very limited, both as to the number of their known species and their area.

The total number of Cryptogamic novelties described in this paper is 47; and while all will prove interesting to the working botanist and devoted disciple of Nature, some of them, it is believed, will prove no less so to the cultivated and cursory, though less technically skilled, observer.

Lastly, and in conclusion, (as I do not wish to repeat my former observations over again, though equally applicable here), I would respectfully beg my hearers, being members of the Institute, to read and note what I have said in my introduction in my paper of last year on this subject, in connection with this present paper.

– 274 –

Class III.—Cryptogamia.
Order I.—Filices.

Genus 16.* Lomaria, Willdenow.

1. L. intermedia, sp. nov.

Plant small; caudex ½–¾ inch, indistinct, formed of the bases of old stipites and wiry roots; tufted, few fronded; fronds sub-erect and spreading, pinnate; stipes rather slender, blackish-brown, glabrous, succulent, somewhat brittle, deeply channelled above, as also is the rhachis. Sterile fronds, 7–8 inches long, (including short stipe, ¾ inch), 1 inch wide, linear-lanceolate, rachis, flexuous, green; pinnæ 16–18 pairs, alternate, distant, membranous, light-green, glossy, thickly dotted beneath with minute red scales, oblong, sides straight, very obtuse, margins crenate, adnate, the lower base much excised and sub-truncate, the upper base slightly sub-auriculate or produced, but not extended on rhachis, 3–4 lobes at top confluent, the uppermost lobe broadly ovate, obtuse; the lowermost 5–6 pairs of pinnæ small, sub-orbicular, and sometimes opposite; veins 4–5-jugate, obscure, the lower forked, upper simple, extending nearly to margin, tips clavate, the lowest basal vein always 3-branched, and proceeding from the rhachis, not the midrib: fertile fronds much longer and more slender, 9–11 inches (including stipe, 2 inches), pinnæ 16–18 pairs, alternate, very distant, sub ½ inch, narrow linear almost filiform, 6–7 lines long, ½ line wide, obtuse, margins sub-crenulate, presenting a regular knobbed or beaded appearance, arising from the clavate tips of the veins, adnate, slightly decurrent, ultimate lobe long and very narrow, the lowermost segments exceedingly small; rich red-brown; margin of indusium finely lacerate, as obtains in L. filiformis, A. Cunn.

Hab. Scattered in damp shaded localities, Seventy-Mile Bush, County of Waipawa; 1880–86: W.C. In forests near Palmerston, County of Manawatu; 1886: Mr. A. Hamilton.

Obs. I. This species is allied to several of our smaller Lomariæ,—as, L. lanceolata, Spr., L. pumila, Raoul, L. membranacea, and L. oligoneuron, Col.,—but more closely to L. membranacea, from which species it differs in its larger size, its crenate (not “dentato-serrate”) sterile pinnæ, which are also of a different shape, more obtuse and distant, excised at their lower and produced at their upper bases, much fewer veined, and minutely dotted with red scales beneath; while the fertile

[Footnote] * The numbers attached to the orders and genera in this paper are those of them in the “Handbook Flora of N.Z.”

[Footnote] † Vide “Trans. N.Z. Inst.,” vol. xvi., p. 346.

– 275 –

pinnæ are also very much narrower, and adnate, with sub-crenulate margins. Those four species form a compact little natural group.

II. After long search, I found 4 small scales at the bases of 2 stipites. These are very short, about 1 line long, black, subulate, with a broad membranous and entire base, and large black oblong cells.

Order II.—Lycopodiaceæ.

Genus 2. Lycopodium, Linn.

1. L. novæ-zealandicum, sp. nov.

Plant small, dependent, lax, soft; main stem slender, 3–4 inches long, single, leafy to base, once forked at top; forks ½–1 inch long, cylindrical. Leaves sub-trifarious, glabrous, shining pale-green, spotted with brown dots, lowermost rather distant, loose, spreading, recurved, sub-linear-spathulate, 4–6 lines long, ½ line wide, transversely wrinkled, narrowed at base and slightly decurrent; tips sub-acuminate, obtuse, thickened, nerve broad and strong; margins entire, pale, sub-cartilaginous; upper leaves much smaller, closer, imbricate, sub-appressed, nerve obsolete. Capsules axillary in upper leaves of main stem and on forks, large for plant, orbicular with a deep sinus, broader than base of leaf, yellow; valves gaping, thickened at margins; spores sub-orbicular, minutely roughish. Scale—or capsule-leaves on forks, sub 2 lines long, subulate, erect, very obtuse at tips, much dilated at base, clasping.

Hab. Epiphytical on fern-trees, open marshy glades in low forest, bank of River Mangatawhainui, near Norsewood, County of Waipawa; 1886: W.C.

Obs. I. Of this little plant I obtained five specimens from three fern-trees, two of them in full fructification and nearly alike in size and shape; two of the barren specimens were a little larger (4–5 inches, main stem), but much the same in form; their colour greener.

II. This is a small species of the Selago section; apparently pretty closely allied to L. taxifolium, Sw., (ap. fig. Hook. et Grev. Gen. Filicum, tab. Ixxxviii.), a Jamaica and St. Helena species; but that plant is much larger, and its leaves are sub-sexfarious, rigid, and acute, and its capsules reniform. This plant is also nearly allied to L. gnidioides, Linn., a Cape and Mauritius species. It differs much from its nearest New Zealand congener, L. varium, Br., in its much smaller size, in its narrower leaves of a different shape, being more lax and remote, and not so thickly set around the stem, in the total absence of quadrangular spikes, its differently-shaped capsules, and its softness. Sir J. D. Hooker has given no less than five drawings of different forms of that variable species in his “Flora

– 276 –

Tasmaniæ,” (tab. clxx.), but all without fructification. Another drawing of that species, with fruit and dissections, is also given by Sir W. J. Hooker, (Ic. Filicum, tab. 112), which is more in accordance with the New Zealand states of L. varium; but all differ widely from this plant.

Order IV.—Musci.

Genus 46. Polytrichum, Linn.

A. Calyptra nearly glabrous.

IV. Polytrichadelphus, C. Müell. (Cyphoma, Hook. fil. and Wilson.)

1. P. polycarpum, sp. nov.

Stems erect, 2 inches high, rather stout, once forked, bare at base. Leaves 3 ½ lines long, thickly set from near base, sub-patent, spreading and decurved below on stem, subulate, acute, glabrous, flat on upper surface not canaliculate, sub-rigid, opaque, narrowly margined, serrate, nerved throughout, darkgreen with brown tips, lurid in age; bases broad, sub-quadrate, 1 line wide, amplexicaul; cells very minute, sub-orbicular distinct and transverse in the margin of leaf near contraction, narrow linear-oblong in the basal portion; perichætial shorter than stem-leaves. Fruit-stalks lateral, slender, erect, 1 ½ inches long, slightly flexuous, twisted at top, light-red, shining, 4–5 to a branch. Capsule broadly oblong, a little contracted at mouth, sub-horizontal and inclined, 2 lines long, somewhat strumous, flat and slightly concave above, conspicuously 2-angled at the sides (sometimes obscurely 4-angled), semi-terete below; light-brown (becoming darker in age), shining, mouth orbicular; teeth 64, rather short, hyaline, acute, sinuses broadly rounded; the circular epiphragm radiate, margin uneven. Spores circular, transparent at centre. Calyptra longer than capsule, narrow linear, 2 ½ lines long, straight, red, glabrous, tip obtuse, hirsute at extreme apex; hairs very short and thick; membranous and lacerate at base.

Hab. Hilly woods, east bases of Ruahine Mountain Range, County of Hawke's Bay; 1885: Mr. A. Hamilton.

Obs. This species will range under Polytrichadelphus, C. Müell., and is allied to P. magellanicum, Hedw. It differs however, from that species in its more simple stems, in its leaves being margined and more serrate, with much larger sub-quadrate bases, (resembling those of P. giganteum, Hook., as given by Schwaeg., tab. cccxxv.), and in their not being canaliculate and lamellate; also, in its slender seta, the sub-strumous form of its capsule with circular mouth, its shorter and more acute teeth with broader sinuses, and its longer calyptra.

– 277 –

Genus 67. Hypopterygium, Bridel.

1. H. hillii, sp. nov.

Plant closely cæspitos in small tufts. Stems about ½ inch high, thickly tomentose throughout with dark brown tomentum. Frond sub-deltoid-orbicular, pale yellowish-green, 5–6 lines broad, the lower branches 2-pinnate, the upper simple. Leaves: on the stem, deltoid-acuminate, nerveless, margins entire slightly uneven, cells long and narrow; on the primary branches, distichous, spreading, close and slightly imbricate, broadly ovate, much apiculate, dimidiate, very thin almost pellucid, stoutly margined; margins serrate; nerve extending about three-fourths of leaf; cells small and sub-orbicular at tips, larger and oblong at centre and base with minute interstitial cellules; dorsal leaves orbicular, very largely apiculate, the mucro stout and acute and nearly half the length of the leaf, margined, slightly denticulate near apex; nerve stout, extending beyond middle; cells as in those of the primary branches; perichætial narrow-ovate, much acuminate, acute; cells very long and narrow. Fruit-stalk, 5–7 to each plant, about ½ inch long, reddish, erect, tip slightly curved. Capsule a little drooping, oblong, red, minutely and regularly papillose, broadest and tubercled near base; cells large, sub-orbicular-quadrate; outer teeth dark-brown, subulate, acuminate, with no median line but a dark line at margins, transversely sulcate; the inner teeth nearly as long as the outer, pale, subulate, acuminate, bifid, tips almost capillary, dark jointed. Calyptra as long as the capsule, dimidiate, narrow, subulate, acute, a little curved, whitish below, tip brown.

Hab. Forests, Daneverke, County of Waipawa; 1885; Mr. H. Hill: forests near Norsewood, same county; 1886: W.C.

Obs. This elegant little fern-like moss is allied to the smaller species of Hypopterygium, (“Sec. I. a. Leaves not mixed with bristles; ** branches 2-pinnate;”) of which we have some half-dozen or more known and described species, but it is very different from them all. I have, with much pleasure, named it after its discoverer, Mr. Henry Hill, B.A., Inspector of Government Schools for the Hawke's Bay District, whose ready zeal and care in collecting, and kindness and liberality in imparting botanical specimens of rare plants, I have long thankfully experienced, as my published botanical papers will abundantly testify.

2. H. pachyneuron, sp. nov.

Plant, rhizome stoutish, creeping, 2–3 inches long, brown, slightly hairy. Stems single, distant on rhizome, erect, 1 inch high, rather slender, glabrous, leafy and green above, bare and brown below. Frond sub-orbicular-cordate in outline, ½ inch

– 278 –

long, green, inclining to pale-green at tips of branches; branches bi-pinnate throughout, very close set and overlapping. Leaves: lateral, distichous, spreading, imbricate, ovate, acute, slightly and distantly serrate at tips, margined; nerve very stout and broad at base and extending beyond middle; cells rhomboidal, larger at base; the dorsal leaves broadly orbicular, apiculate, margined; margins entire, slightly uneven; nerve vanishing beyond middle; cells oblong, small at tip and margins, larger at centre and base; stem leaves similar to dorsal; perichætial narrow oblong-lanceolate, very acuminate, entire; cells narrow oblong rectangular. Fruit-stalk: 8–9 on one plant, each singly arising from the base of a branch on the main stem, or from a fork of the primary branches, slender, erect, red, 5 lines high, shorter than frond; base very filiform, vaginant; vagina large, cylindrical, dark-brown. Capsule sub-erect and horizontal, about 1 line long, oblong, reddish, smooth, slightly rugose at base; outer teeth dark-brown, subulate, with a dark median line, very closely transverse-sulcate, edges much roughened (sub-denticulate) with numerous dark teeth, greatly acuminate, tips flexuous, curved; inner teeth just as long as outer, pale, remotely barred with a median line, acuminate, bifid for one-third of length from tip, with three filiform jointed ciliæ, shorter than teeth, alternate between them.

Hab. Near Wairoa, Hawke's Bay; 1885: Mr. A. Hamilton.

Obs. This is another species of the same subsection as the preceding, and is also pretty closely allied to its known New Zealand congeners.

Capsule smooth, shining, oblong, equal, rather less than 1 line long, brown, slightly tubercled at base, sub-erect and horizontal; cells small, oblong-orbicular; outer teeth much acuminate, dark-brown, closely trabeculate, free, with stout thickened margins, rough at edges with bars largely protruding towards tips, and two dark stout longitudinal medial lines close together; inner teeth long, very acuminate, finely hair-pointed, white, with distant trabeculæ and a single median line. Operculum half the length of capsule, rostrate, reddish, smooth, shining, acuminate, acute, black-tipped, centre reddish-brown, base much fimbriate; fimbriæ recurved, light-brown, obtuse, of unequal lengths.

Hab. Close to a waterfall, wet dripping-sides of shaded cliffs, banks of the River Mangatawhainui, near Norsewood, County of Waipawa; 1886: W.C.

Fruit-stalk (immature) ½ inch long, black, stout, flexuous, twisted, much thickened at base. The leaves when dry are distant and much crisped, but soon expanding in water.

Hab. On the ground, edges of a swamp, dense forest near Norsewood, County of Waipawa; 1886: W.C.

Obs. A species near to H. pseudopetiolata, Col., but differing from that species in its larger size and very much larger and broader leaves, that are only very minutely serrulate and imbricate; their cells also are unequal, with a stouter and longer nerve.

Order V.—Hepaticæ.

Genus 2. Jungermannia, Linn.

1. J. pygmæa, sp. nov.

Plant minute, erect, 2 (rarely 3) lines high, of close, compact growth, pale-green. Stems highly cellular. Leaves sub 20, orbicular, narrowed at base, semi-amplexicaul, not decurrent, imbricate, vertical, sub-recurved at tips, margin entire but slightly uneven; cells small, orbicular, and minutely beaded at apex of leaf, larger and oblong, with minute triangular cellules in the interstices in the centre and at the base, and minute sub-quadrate and regular at the margin, giving the leaf a margined appearance.

Capsule small, brown; valves oval, obtuse, slightly margined, striate with dark-brown wavy lines and numerous minute transverse ones; cells oblong.

Hab. On wet sides of clayey and sandstone cuttings, closely intermixed with a minute Fissidens, and forming one compact and spreading mass; Glenross, County of Hawke's Bay; 1886: Mr. D. P. Balfour.

Obs. A species very near to J. humilissima, Col., (“Trans. N.Z. Inst.,” vol. xviii., p. 236, and to other small allied species mentioned there), but differing mainly from that species in the form of its perianth and its capsule, in the cells of its leaves, and in its smaller size.

Genus 3. Plagiochila, Nees and Mont.

1. P. polycarpa, sp. nov.

Rhizome creeping, long, much branched. Stems dendroid, erect, 6–9 inches high, woody, sub-rigid, bare and compressed below cylindrical above, black, glossy, bipinnately branched; branches ascending and horizontal, very numerous, especially above, irregular in length—sometimes a branch as large and as thick as the main stem proceeds horizontally from it near the base. Leaves light-green when young, olive-green when old, much crisped when dry, closely set, imbricate, largely decurrent, ventral margins cilio-denticulate; teeth few, distant, but closer and smaller at apex; dorsal margin entire and very oblique; cells sub-orbicular. Main stem 2 ½ lines wide (including leaves), leaves large, somewhat elliptic-orbicular, apices round, their ventral bases much produced and clasping; branches (with leaves) 1 ½ lines wide, their leaves smaller and somewhat deltoid in outline; involucral sub-obovate, narrow, sub-vertical, ciliate on ventral margin and at apex, dorsal margin entire.

– 281 –

Perianth terminal on short lateral branchlets, green, broadly-elliptic, apiculate, sub-inflated, mouth large, gaping, lips entire, thickened, incurved, with 3–4 very minute ciliæ (sub lente) at tip, the mucro sometimes split or minutely bifid; seta short, slightly exserted, nodding; capsule oval, dark red-brown, small for plant; valves oblong, obtuse; elaters bi-spiral, adhering largely to margins. The male plant is more slender, with smaller leaves, narrow spikes, and much attenuated apices.

Hab. In wet dark woods in deep gulleys between hills, growing luxuriantly and thickly in very large continuous patches of several feet, on rotten logs, roots and bases of trunks of large trees, completely covering them; near Norsewood, County of Waipawa; 1885–86: W.C.

Obs. This fine species will rank with those other known New Zealand dendroid Plagiochilæ,—viz., P. gigantea, Lind., P. stephensoniana, Mitt., P. sub-similis, Col.,* etc. It also has affinity with them all, mostly, perhaps, with P. stephensoniana, but differing from that species in its perianth and involucral leaves, colour, and manner of growth, being much and largely branched at the top. The form of its leaves on the ventral side in their upper basal portion is much like those of P. deltoidea, and P. cristata, Lind., (and of some others), being largely-produced and sub-amplexicaul.

2. P. obscura, sp. nov.

Rhizome creeping, long, stout. Stems dendroid, erect, 5–6 inches high, semi-depressed and sulcated below, dark, stout, leafy from base, much branched above; branches sub-tripinnate, reddish-brown. Leaves very numerous, close, imbricate, cordate, amplexicaul, sparsely ciliate-dentate at apex and apical portion of ventral margin; the dorsal base of leaf wavy and largely decurrent, and nearly meeting on the stem that of the opposite leaf; the base of the ventral margin much produced beyond the stem; the young leaves light-green, the old ones dark-green; cells minute, orbicular; guttulate, sub-opaque. Involucral leaves similar, but smaller and obovate; teeth coarse, each containing many cells. Perianth terminal on very short lateral branchlets, green, elliptic-orbicular, obtuse, apiculate, entire, the mucro having 4 short teeth (sub lente); seta exserted, very short; capsule small, oval, dark-brown; valves sub-acute.

Hab. On decaying logs and branches, wet dark woods near Norsewood, County of Waipawa; 1886: W.C.

Obs. A species allied to the preceding, P. polycarpa, but a smaller, coarser, and darker plant, with differently shaped and opaque leaves.

[Footnote] * “Trans. N.Z. Inst.,” vol. xiv., p. 340.

– 282 –

3. P. suborbiculata, sp. nov.

Plant dendroid, 3–4 inches high; stem (and main branches) black, bare at base, leafy above, tripinnately branched at top; branches long, irregular, spreading; sometimes a branch, with its numerous upper and close bushy branchlets, is larger than that whence it sprang; branchlets clear greènish-brown, curved, drooping, 2 ½ lines wide (including leaves). Leaves alternate, distant on main stem and branches, closer on branchlets, but not much imbricate; green when young, dusky-green when old; those on main stem sub-reniform-orbicular, 2 lines diameter, horizontal, patent, slightly amplexicaul; on branches orbicular or orbicular-cordate; margins largely denticulatociliate (almost spiny), except the basal portion of the dorsal margin; teeth or spinous ciliæ reddish, irregular, coarse, jointed, the largest with 2–3 lateral cells at their bases; marginal interstices between teeth curved and rounded; cells large, orbicular, and oblong, with thick double walls and clear triangular dots in the interspaces, smaller and more compact in a regular line on the margins. Involucral similar, but larger and spreading. Perianth terminal, free, obovate, 3 lines long, curved, compressed; lips semicircular, much produced, ciliate-toothed, extending round apex and slightly down the sides; base cylindrical, peduncled.

Hab. Dry hilly forests near Norsewood, County of Waipawa; 1886: W.C.

Obs. This species is very near P. gigantea, Lind., which it much resembles in form and general appearance, though a smaller plant. It differs, however, from that species in its larger and more orbicular leaves and in their areolation, their margins being much more coarsely toothed and sub-spiny, and their dental interspaces rounded; its perianths, too, are much more round and produced at their tips, with longer, more numerous and extensive ciliate teeth; and its involucral leaves are more distant and spreading.

4. P. exilis, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant creeping at base, sub-erect, 3–4 inches high, excessively slender, few and loosely branched; branches diffuse, distant, long, often 3 branchlets opposite and near each other spring from near the top of the main stem, and a sub-horizontal one from close under perianth; stem (with leaves) 1/10 inch wide, red, smooth. Leaves light-green, small, alternate, distant, obovate, apices very obtuse and truncate, closer and very slightly overlapping at tops of branches, ventral margin and apex coarsely and irregularly denticulate, (mostly 10 teeth on ventral margin and 2–3 at apex), dorsal margin entire, an oblique ridge or thickening near the margin extending to stem (giving the

Hab. On wet logs, etc., forming closely-growing loose tangled masses; low wet woods near Norsewood, County of Waipawa; 1886: W.C.

Obs. In general form and habit this species will rank near to P. tenuis, Lind., (an East Indian and West Indian species), and the male plant with that of P. deltoidea, Lind. It is also pretty closely allied to the following species, P. distans.

5. P. distans, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant creeping, slender, wiry, procumbent, and sub-erect. Stems delicate, 1 ½–2 inches high, leafy to base, simple, forked at top and sometimes sub-fascicled with 2–4 branchlets; tops of stems sub-flabellate; stems (including leaves) mostly about 1 line wide, the largest sometimes 1 ½ lines; stems light reddish-brown. Leaves on stems small, alternate, very distant, sub-obovate, dimidiate, flat, spreading, ventral margin much arched, dorsal straight, a few large distant teeth (4–7) at apex and on anterior portion of ventral margin, generally 3 spinous teeth at apex, the one at the outer anterior angle being the longest, dorsal margin entire; leaves generally larger at tops of branchlets and about the perianth, light green; cells orbicular, with thick walls and minute circular cellules in the interstices. Involucral leaves similar, erect. Perianths terminal on branchlets, obovate, 1/10 inch long; mouth narrow; lips largely ciliate-dentate; teeth few, flexuous; cells as in leaves. Male plant still more slender, sometimes 3 spikes on a branch, with leaves in the interspaces, each spike about 1 ½ lines long; scales sub-erect, tips 2-fid. The tips of the branches are sometimes flagellate and scaly; some of the stems are also exceedingly fine and slender, being only ½ line wide, including their pinnate leaves.

Hab. On trees, in low wet woods, forming rather large and densely compact patches; near Norsewood, County of Waipawa; 1886: W.C.

– 284 –

Obs. A species nearly allied to the preceding, P. exilis, mihi; and also to P. distinctifolia, Lind., a West Indian and South American species, (and also said by Lindenberg* to have been “found in Dusky Bay, New Zealand, Herb. Hook.”; but it is not included by Sir J. D. Hooker in the “Flora N.Z.,” nor the “Handbook Flora N.Z.”; hence, I suppose, some slight error in the Dusky Bay hab., possibly an error for Staten Land, near Cape Horn). This species differs from P. exilis in its leaves being less toothed with rounded apices, and without the oblique and decurrent ridge, so striking in the leaves of that plant, and also in their widely different areolation: the spikes, moreover, of the male plant of this species are much smaller, with only 2 teeth to their sub-erect (not recurved) scales. This species is also shorter and much more slender and filiform, and of a different habit of growth.

Cells sub-orbicular, very obscure, but regularly disposed in rows between dark longitudinal lines, appearing as if each cell was composed of 5 cellules, separated by a star-like division, and as if there were two layers of superimposed cells. Stipules free, rather large (for plant), as broad as the leaves at their bases, distant, appressed, highly cellular, cuneate-quadrate, 4-lobed; lobes short, broad, and very obtuse. Flagellæ O.

Hab. On the ground, thickly overrunning loose dry vegetable débris; low damp spots, forests near Norsewood, County of Waipawa; 1886: W.C.

Leaves, a pleasing emerald-green, distichous, regular; stem leaves close, patent, not imbricate, broadly cordate-ovate, dimidiate, apiculate, margins entire but slightly uneven, with usually 4 large lacinia-like ciliæ at the base on each side; cells sub-orbicular, distinct; leaves on branches imbricate, orbicular-elliptic, largely apiculate, margins entire, auricles clavate, darkred when mature, with a minute subulate fimbria at the base; cells large, hexagonal, with minute interstitial cellules. Stipules on main stems 4-partite, segments ciliato-laciniate all round, ciliæ jointed; sinuses long, clear; cells oblong; stipules on the branchlets similar but very minute, bearing 2 very small claviform appendages, similar to those on leaves but much smaller.

Hab. On bark of trees, and among mosses on the ground; dark woods near Norsewood, County of Waipawa; 1886: W.C.

Obs. This truly elegant species has affinity with both P. claviger and P. palpebrifolius, Gottsche, but differs from them and from all other known species in several particulars, especially in colour and in form of leaves and stipules.

2. P. fimbriatus, sp. nov.

Plant prostrate, creeping; stems stout, flexuous. pendulous, 4–6 inches long, 3-pinnately branched; branches straggling,

– 295 –

very irregular in length, overlapping each other; branchlets numerous, close-set, alternate. Leaves mostly pale yellowish-brown, the upper layer and more exposed dark-orange and rich bright red-brown; main-stem leaves sub-imbricate above on stem with crisp sub-vertical margins, having a fissured scaly appearance, orbicular-cordate, very apiculate, margins entire but slightly uneven, largely amplexicaul, the sinus broad and circular, with several long irregular-curved fimbriæ and ciliæ at base; branch leaves imbricate, distichous, sub-orbicular, apiculate (sometimes sub-acute and obtuse), margins entire with long irregular laciniate fimbriæ at base; auricle clavate, dark-purple in age with several long flexuous fimbriæ at base; cells clear, orbicular, with minute interstitial cellules. Stipules on main stem large, sub-quadrate, 4-partite; segments largely ciliate on all sides; ciliæ long, recurved, flexuous, jointed; stipules on branchlets similar but smaller, with a dark boss or blotch at central base, and bearing two small dark claviform appendages similar to those on leaves, and ranging with them: cells oblong-orbicular, very clear, each of the segments having a narrow marginal line of compacted minute cells.

Hab. On trees, often overrunning mosses, etc., Seventy-mile Bush, between Norsewood and Woodville, County of Waipawa; 1885–86: W.C.

Obs. A species allied to the preceding, P. smaragdinus; but more nearly to P. claviger, and P. taylori, Gottsche. It is, however, a much larger, robust, and coarser plant; differing from them, and from all known species, in its large clasping and fimbriate stem-leaves, its largely fimbriate and ciliate stipules, and in its rich striking colours.

Genus 21. Madotheca, Dumort.

1. M. latifolia, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant prostrate, creeping, diffuse. Stems stout, brown, 3–4 inches long, 21/2 lines wide, bipinnate; spreading irregularly over each other in loose horizontal layers, and so forming small cushioned tufts; branches alternate, short, flat, patent. Leaves darkish-green when fresh, (young leaves and branchlets light-green), closely and uniformly set, much imbricated, convex, reniform-orbicular, decurved, dorsal margin entire, the apex or outer angle much incurved, base waved; the ventral lateral margin on stem very uneven; lobule sub-orbicular-elliptic, larger than stipule, crisp; cells orbicular, with thick walls and minute interstitial cellules; involucral 4, oblong-ovate, (2 of them being smaller and narrower), largely ciliate; ciliæ jointed; cells as in leaves, only larger and clearer at centre and base; a dark-green outer leaf largely produced and sub-vertical, much incurved and enwrapping the apical margin, finely ciliate; capsule (immature)

– 296 –

enclosed, globular, dark-green. Stipule oblong, recurved, apex retuse, margin entire, much waved, especially at the base.

Hab. On branches of trees, slightly adhering to their bark, and to foliaceous lichens, and to its own under-branches; Seventy-mile Bush, County of Waipawa; 1882–86: W.C. Forest near Palmerston, County of Manawatu; 1886: Mr. A. Hamilton.

Obs. This species much resembles M. stangeri, Gottsche, (and its vars.), but it differs from them in the shape of its leaves, which are much more reniform or transversely elliptic, in its largely ciliated involucral leaves, in its oblong and retuse stipules that are not gibbous, and in its orbicular cells, as well as in its size and colour. It is a fine and pretty plant, and though its stems and branches are not so large and long as those of M. stangeri, they are quite as wide as the widest of them.

2. M. amœna, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant pendulous; stems 5–6 inches long, 23/4 lines wide, pinnate, mostly simple, few-branched and forked at tips; bases bare, black, wiry, sub-rigid; colour a lively light-green. Leaves closely regularly and largely imbricated, but not overlapping their opposite bases on stem, broadly elliptic, margins entire, the lateral sparingly and finely toothed towards stem, apex decurved; lobule very slightly affixed to leaf, oblong, broader at apex, ciliate; ciliæ irregular, jointed; cells small, orbicular, with minute interstitial cellules (much as in the preceding species M. latifolia, but smaller). Stipules small, rather distant, sub-deltoid-cordate, with rounded tip, and basal angles produced and clasping, tip recurved; narrowly margined, marginal cells minute, uniform; margins entire, but irregular at base; cells remarkably minute, and of various sizes and shapes, mostly oblong.

Hab. On trunks of trees, hilly forests, Glenross, County of Hawke's Bay; 1886: Mr. D. P. Balfour.

Obs. A species near to the preceding; and also to M. stangeri, and its vars.; but differing in its usual long simple form, in appearance and in colour, in the size of its cells, and particularly in the shape and structure of its small margined stipules, and in its different lobule.

Genus 23. Frullania, Raddi.

1. F. novœ-zealandiœ, sp. nov.

Stems slender, 1 inch long, wiry, flexuous, dark-coloured, pinnate, rarely bipinnate; branchlets few, alternate, irregular in length. Leaves pale-green, very slightly imbricate, broadly ovate, sub-acute and obtuse, margins irregular, ventral base patent not inflexed, those on the main stem larger than on

– 297 –

branches; lobule brown-purple, rather large and prominent, galeate with a long acuminate depending tip that is often recurved. Stipules: on main stems, sub-rhomboid-quadrate, deeply bibbed; lobes divergent, tips acuminate, with 2 teeth on each lobe outside; on small branches, ovate, deeply bilobed; lobes lanceolate, entire. Cells minute, orbicular, regularly disposed in longitudinal lines.

Hab. On bark of trees, intermixed with other Hepaticœ and mosses; forests, Glenross, County of Hawke's Bay; 1886: Mr. D. P. Balfour.

Obs. A species belonging to Section 1, Division ***, p. 536 of “Handbook N.Z. Flora;” and having affinity with F. hampeana, Noes, and with F. spinifera, Hook. fil. et Tayl., but differing from them both in several particulars.

2. F. delicatula, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant very minute, delicate pale-green. Stems slender, 1–11/2 inches long, 1/30 inch wide (including leaves), bipinnate, irregularly and sparingly branched; branches rather long for the plant. Leaves round (longer than broad), close but not imbricate, margins entire and slightly recurved, basal portion not inflexed; lobule small, arched, slightly deflexed, tip obtuse, not produced beyond margin of leaf, pale purple. Cells minute, sub-orbicular, crowded, indistinct. Stipules reniform-orbicular, entire, adpressed.

Hab. Hilly woods at Pohue, north-west from Napier, County of Hawke's Bay; 1885. (A few fragments, found mixed among larger Hepaticœ collected there by Mr. A. Hamilton.)

Obs. A very filiform, delicate, tender plant, remarkable for its whole entire stipules.

3. F. rotundifolia, sp. nov.

Plant small, erect, not ½ inch high, but growing thickly together in densely-compacted patches; dark green, but appearing blackish together in the mass.

Stems creeping, 2 inches long, bipinnate, wiry black and bare below, but stout, and of same colour as leaves, and very much branched at top; branchlets alternate, very short. Leaves very close-set, imbricate, patent, sub-vertical, wavy, recurved, rather opaque, orbicular; margins entire, but slightly irregular (sub lente); basal portion not infiexed, sub-amplexicaul; lobule small, sub-galeate, same colour as leaf, tip obtuse, not produced; involucral lanceolate, acuminate, very acute, margins entire. Stipules orbicular, with a small broad sinus at apex, which is broadest and rounded at base, and margined; tips somewhat conniving.

– 298 –

sub-cylindrical, slightly clavate, apiculate, smooth. Capsule oval, whitish; seta produced, nodding; valves oval, membranaceous, spreading, not cut to base; elaters as in gen. descr.

Hab. On upper branches of tall trees, adhering to bark and overrunning lichens (Stictœ); forests, Norsewood, County of Waipawa; 1886: W.C.

Obs. This species is rather peculiar; small though it is, it makes a show from its densely clustered habit of growth and patent sub-transverse leaves; it has also a pretty appearance when in fruit, with its spreading white 4-valved capsules peering above the tips of its dark leaves, resembling minute starry flowers. It is also singular from the curious sinus of its stipules, which, as far as I know, is quite a unique character.

4. F. minutissima, sp. nov.

Plant very small, about 2–3 lines high, erect, thickly gregarious, appearing black in the mass. Stems procumbent, sub ½ inch long, much implexed, bipinnate; branchlets alternate, very short. Leaves on main stem distant, on branches close and touching but scarcely imbricate, sub-orbicular and broadly elliptic, margins entire, tips rounded and recurved, basal portion inflexed in a minute triangular interlobule or lobelet between lobule and stem, brownish, the young leaves and branchlets light-green; lobule large (for plant), nearly ⅖ths of leaf in size, distant from stem, elliptic-clavate, broadest at apex, erect a little inclined, produced at base slightly beyond margin of leaf, dark purple; involucral leaves oblong-ovate, apiculate, entire. Stipules orbicular, sinus large, angle acute at base and very broad at margin. Perianth obovoid, triangular, sides slightly concave, apex truncate, mucronate, mucro obtuse, dark brown, shining. Cells excessively minute, orbicular-oblong with microscopical interstitial cellules.

Hab. On branches of trees, forming thickly compact and spreading patches; banks of River Mangatawhainui, near Norse-wood, County of Waipawa; 1886: W.C.

Obs. This very minute species is readily distinguished from all other known New Zealand species by its large erect lobule.

5. F. scabriseta, sp. nov.

Plant procumbent, creeping, spreading. Stems stout, 1–1 ½ inches long, brown, 3-pinnate, much branched; branches long, leafy throughout. Leaves alternate, close-set on main stem, slightly imbricate on branches, broadly oval, light-green, margins entire but slightly uneven, recurved; lobule same colour as leaves, small, arched, tip short, obtuse, scarcely produced beyond leaf; involucral leaves sub-obovate, entire; cells small, sub-oblong-angular, with thick walls composed of a chain of very minute

– 299 –

cellules. Perianth sub-inflated, narrow - oblong, triangular angles sharpish, apex rounded, mucronate, mucro obtuse, lips entire. Calyptra broadly clavate, green; seta white, nodding, sub-rugulose; valves broadly oval, obtuse, spreading, recurved, brown with a rather large white circular base; elaters numerous, reddish, stout, truncate, the tip of the hollow tube containing the elater closed and capitate by the elater, and broader than the tube.

Hab. On trees, in low wet woods near Norsewood, County of Waipawa; 1886: W.C.

Obs. A species having some slight affinity with F. spinifera, Hook. fil. et Tayl., in its general appearance; but differing in leaves and lobules, in its more sharply-angled perianth with entire involucral leaves, in its scabrid seta, and in its peculiar capitate elaters.

6. F. implexicaulis, sp. nov.

Plant minute, much implexed and compact in small dark-coloured masses. Stems ¾-1 inch long, 2-pinnate, flexuous, black, wiry. Leaves alternate, oblong-orbicular, (sometimes broadly ovate and sub-acute on the branches), dimidiate, margins entire, sub-vertical and recurved on the main stem, convex and very close-set yet scarcely imbricate on the branches, brownish-green, the young leaves and branchlets bright-green; lobule large, set close to stem, prominent, hooded, the arch high, tip acute but not acuminate nor decurved, and scarcely produced beyond margin of leaf, brown-green; involucral leaves sub-obovate-oblong, entire; cells small, sub-orbicular with minute interstitial cellules. Stipule small, convex, sub-orbicular, broader than long with apex produced, narrowly margined, bifid; sinus large and deep, and wide at tips. Perianth oblong-obovate, sub-inflated, rugulose, plaited above, tip produced and obtuse with a mucro, mouth shortly fimbriate; calyptra turbinate; spores large, sub-angular, light-brown.

Hab. On pendent branches of living trees, forming small scattered much implexed dark clusters; edges of forests near Norsewood, County of Waipawa; 1886: W.C.

Obs. This species in its general appearance resembles F. minutissima (supra), although it differs widely in the habit of growth, as well as in several important characters (vide descript.).

Genus 25. Noteroclada, Taylor.

1. N. longiuscula, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant pale yellowish-brown, prostrate, creeping, adhering on ventral surface by numerous fine pale rootlets. Stems 3–4 inches long, 1/10 inch wide (including leaves), simple below, few-

– 300 –

branched above, leafy throughout; branches alternate, long, irregular, tips involute. Leaves regular, very close, largely imbricate, sub-vertical, broadly oval, wavy, decurrent, margined; margins entire, but slightly irregular with a very narrow marginal line; leaves when dry secund, vertical above stem and closely appressed to each other. Cells minute orbicular, guttulate, smaller at margin, larger and clearer at base, with minute interstitial cellules. Involucre (or perianth) terminal from a short stout branch near base, sessile, erect, sub-oblong-ovate 2 lines long, plaited at top, mouth large, tips finely lacerate. Two short scaly flagellæ depending from branch a little below the involucre.

Hab. Hilly woods at Pohue, north-west from Napier, County of Hawke's Bay; 1885: Mr. A. Hamilton.

Obs. A species widely differing from the few other known ones. I have received several leafing specimens of this plant, but only one of them bore an involucre (old) and flagellæ more and perfect ones are wanted.

Genus 30. Symphyogyna, Mont. and Nees.

1. S. platycalyptra, sp. nov.

[The section below cannot be correctly rendered as it contains complex formatting. See the image of the page for a more accurate rendering.]

Plant diœcious, terrestrial, highly gregarious; stipitate, erect, rising from a short stout simple or few-branched succulent subterraneous rhizome, that is slightly hairy with fine weak hairs; generally 3 stipes, each about 1 inch apart, spring from one rhizome, the rhizomes being thickly matted. Frond circular, 1 inch diameter, of a pleasing green, divided into two main branches, that are again equally divided and largely overlapping, each flabellate division containing 3 branchlets, which are again dichotomous, and broadly margined to their bases; the main branches, however, are not margined; margins entire, slightly sinuous; main sinuses broad, open; ultimate sinuses narrow; lobes short, overlapping, broad in middle, not linear, much waved, apices retuse; cells small, orbicular; the nerve broad and strong, but not extending to apical margin. Stem stout, succulent, 1–21/2 inches high, cylindrical below, compressed above. Female plant: fructification regular, generally 2–4, solitary at upper forks beneath, sometimes, but rarely, 1 at the main forking; involucral scale large, 2 lines wide, sub-reniform, slightly bilobed, undulate, somewhat plaited, recurved, with a glossy knobbed protuberance at the base; margin sub-sinuous, entire; cellules large, orbicular; 1–2 minute scales behind, and so enclosing calyptra. Calyptra very broad, 1/10th inch wide, 11/2–2 lines long, flat, membranous, smooth, shining, slightly laciniate at apex, very light-green; cellules quadrangular-oblong. Capsule (immature within) globular, large, smooth, green, surrounded by 8–10 large cellular pistillidia that spring

– 301 –

from beneath. Male plant: fructification irregularly scattered beneath in sub-globular tubercular lumps on upper portion of stem and on the branches.

Hab. Plentiful in a muddy swamp, in a deep low dark shaded forest near Norsewood, County of Waipawa; 1886: W.C.

Obs. I. This species is peculiar from its wide, flat, strapshaped calyptra and its globular capsule, also from its strictly diœcious manner of growth. It forms dense compact patches or small beds, something like thick beds of young cress (Lepidum sativum) or parsley: and these are generally of two kinds or sizes: the larger (taller and bigger fronds and finer patches) contain only male plants, and the smaller and shorter the female ones, and these never appear to intermix. Indeed, I was a very long time (parts of two days), before I found a single female plant bearing fructification, and was about giving it up in despair, as I had confined my search to the finer masses; and it was only by chance that I happened to look among the smaller-sized plants.

II. This species has pretty close affinity with S. longistipa, S. fetida, and S. megalolepis, Col.,* and with S. flabellata, Mont., (“N.Z. Flora,”) but is distinct from them all.
