Notes on Some New Zealand Plants and Descriptions of New Species.
[Read before the Otago Branch, November 10, 1942; received by the Editor, July 7, 1943; issued separately, December, 1943.]
Ranunculus sericophyllus var. simpsonii (Ckn. et Allan) Simpn. et Thomn.
The authors' (1942–22) record for the occurrence of this plant at Lake Man, Amuri Pass, must be deleted. Some hybrids between the local forms of R. monroi and R. enysii show a remarkable resemblance.
Ranunculus depressus T. Kirk var. stewartiae var. nov.
Ab typo foliis late deltoideis, 6–8 mm. diam., floribus fere sessilibus recedit.
A small, closely matted, pale green plant 2–3 cm. high, spreading by short arching stolons. Roots slender, soft, white. Leaves radical, 3 cm. long; petiole much longer than the blade, slender, depressed, ascendant at the tip, flattened, mottled with black, sparsely dotted with long straight hairs, with a short, wide, membranous sheathing base; blade broadly deltoid, 6–8 mm. diam., rather deeply 3 lobed or divided into 3 lobed segments, the lobes rounded, or the lower ones toothed at the base; margins ciliolate. Flowers single, sessile or with a short scape, 3–4 mm. diam.; sepals 5, ovate, obtuse, membranous; petals 5, yellow or greenish, slightly exceeding the sepals, oblong, obtuse, clawed, with a single minute gland. Fruiting head 5–6 m.m. diam., usually sunken amongst the leaves; achenes 2 mm., diam. or less, glabrous, slightly compressed, the hooked style not hardening, the beak short and stout, obliquely placed.
Habitat: Stream banks and moist ground.
Type specimen from the banks of Freshwater River, Stewart Island, in the Herbarium, Plant Research Bureau, Wellington.
The plant flowers throughout summer and autumn, and spreads rapidly, both vegetatively and by seed, in cultivation. It differs from the type in leaf shape and in the almost sessile character of the flowers and fruits.
Corallospartium crassicaule (Hook. f.) J. B. Armst.
Plants collected at Mt. Torlesse and Lake Ohau by Haast and at Lindis Pass by Hector and Buchanan were described by Hooker (1864–48) as Carmichaelia crassicaulis. Armstrong (1880–333) erected the genus Corallospartium for its reception, and he stated that C. crassicaule occurred “in numerous localities in the Alps of Nelson, Canterbury, and Otago.” Kirk (1899–107) described
specimens collected by Buchanan at Lindis Pass as var. racemosa, but he retained that locality also as one of the habitats for the species. We have not seen specimens from L. Ohau, where var. racemosa, might be expected to occur, but to establish a definite habitat we accept Haast's Mt. Torlesse specimens as the type of the species. The branchlets of C. crassicaule are bronze green, often yellowish in repressed or dried specimens, 5 mm. diam., compressed, rounded at the edges and closely striated. The inflorescence—rhachis, pedicels and calyx—are densely woolly pubescent, the calyx teeth are rounded, and the flowers are nearly 1 cm. long. The species occurs in arid districts in Canterbury and Central Otago.
Var. racemosa T. Kirk.
The variety is much like the species, and we cannot support Cockayne and Allan (1927–50) in according it specific rank. The branchlets are narrower 4 mm. diam., less rigid than those of the species, darker bronze green, and striated by narrower lines. The flowers, described by Kirk (loc. cit) as “less than ½ in. long,” are 1 cm. long, equalling or even slightly exceeding those of the species, and the inflorescence is similarly pubescent, but the calyx teeth are longer and acute. The variety is separated from the species by its narrow, less rigid branchlets and by the acute calyx teeth. Its distribution is not yet well known, but it occurs in less rigid situations than those occupied by the species. Our specimens and plants were collected at Lindis Pass and from grassland slopes to the west of L. Wakatipu.
Geranium microphyllum Hook. f.
To the type of G. microphyllum we refer plants with the open, cuneate, acutely segmented leaves of Hooker's (1844–8-t 5) illustration, found in moist grassland and swamps above 400 m. altitude, and common in sphagnum bogs on the hills near Dunedin. The lower portion of the peduncles are sparingly hairy, but the upper portion, and the pedicels and calyx, are densely clothed with retrose glandular hairs. The carpels are silky and the seed obscurely striated.
Var. obtusatum var. nov.
Foliis fere orbiculatis brunneis vel fuscis pubescentibus profunde angusteque incisis, pedicellis calycibusque pubescentibus distinguitur.
Leaves orbicular or broader than long, brownish or reddish brown, pubescent by fine retrose hairs; segments 3–5 lobed, petioles, peduncles and pedicels pubescent. Flowers white; calyx with long hairs. Carpels silky. Seed striated.
Habitat: Grassland from near sea-level to 900m.
Type specimen from Flagstaff Hill, near Dunedin, in the Herbarium Plant Research Bureau, Wellington.
A common grassland plant easily separated from the form we refer to the type.
Var. discolor var. nov.
Foliis supra fulveis flavo-macculatis, late incisis, pedicellis parce pilosis distinguitur.
Petioles dotted with spreading hairs. Blade rounded, broader than long, with 5–7 openly divided segments and the sinus rather wide, yellowish brown above, mottled with pale yellow, sparingly strigose, paler beneath and almost pubescent; segments with 3–5 rounded lobes or the outermost lobes subacute; peduncles and pedicels sparingly pilose. Flowers white; calyx with long hairs. Carpels dotted with minute hairs. Seeds striated.
Habitat: Moist shaded valleys and bush margins.
Type specimen from the Port Hills near Christchurch, in the Herbarium Plant Research Bureau, Wellington.
The variety was first shown to us by Mr. W. B. Brockie, and with him we collected it on the Port Hills and in the tributary valleys of the Hope River, near Hanmer.
Geranium sessiliflorum Cav.
It is apparent, by his inclusion of both the type and var. glabrum in the New Zealand flora, that Cheeseman (1925–534) did not fully appreciate Knuth's (1906–534) conception of a compound species with its type, equally with other differing forms, given a varietal name. Knuth separated G sessiliflorum under 4 varietal headings, and the present authors are obliged to Dr. H. H. Allan, Wellington, for copies of the descriptions and a note regarding the illustration of var. typicum.
G. sessiliflorum Cav. var typicum R. Knuth “Pedunculi petiolique retro-adpresse pilosi. Indumentum foliorum densum, sed non argenteum—Fig. 15.”
The plate shows 3 branches with the flowers very numerous and densely massed at their tips, the terminal branch in full flower and the laterals in bud. The author makes no mention of its occurrence in New Zealand, but allows it a wide range in South America from “Peru und Bolivia durch Chile bis Argentinien und Patagonia; auf alpinen Matten.” Plants with this densely floriferous habit are not known in New Zealand. Var. lanatum and var. compactum are South American plants known only from specimens collected in Bolivia, and var. glabrum of “New Zealand and Tasmania” is then the only described representative of the species left for inclusion in the flora. Without a varietal name that would distinguish the form to which the all-embracing epithet is applied, the specific term G. sessiliflorum has, in Knuth's sense, no meaning and it must be removed from the flora.
Var. maculatum var. nov.
Laminis supra purpurei-maculatis, floribus puniceis breviter pedicellatis distinguitur.
An openly leafy plant with the petioles long, sub-erect or spreading, slender. Leaves openly segmented; segments broad, 3–5; lobes rounded, mucronate, greyish green, the upper surface blotched at the base and irregularly spotted with purple, closely dotted with retrose hairs, lower surface of even colour, more closely
hairy and when young the whole under surface and the tips of the petioles almost concealed, older petioles more or less closely dotted, the peduncles and pedicels short, densely covered with white hairs. Flowers pink; calyx almost concealed by long hairs, carpels silky.
Habitat: Lake shores subject to flooding.
Type specimen from the shores of Lake Lyndon, between the grassland and the lake, in the Herbarium Plant Research Bureau, Wellington.
Best recognised by the colouring of the leaves and the shortly pedicelled pink flowers.
Var. arenarium var. nov.
Var. glbri simile sed omnino molle aliquantulum carnosum, foliis glaucis.
Similar in habit to var. glabrum, but everywhere soft and somewhat fleshy. Leaves orbicular, closely lobed, divided at the base, unusually appressed to the ground, petioles and peduncles tinged with purple; blade pale glaucous grey, softly and finely pilose. Flowers white.
Habitat: Sand dunes at Stewart Island and the east coast of Otago.
Type specimen from Paterson's Inlet, Stewart Island, in the Herbarium Plant Research Bureau, Wellington.
Cockayne (1909–55), who was of opinion that “if constant from seed it should have a name,” considered this to be a more robust plant than var. glabrum, with longer petioles and peduncles, but such characters are dependent upon the number of stems branching from the rootstock and large plants form rounded leafy masses with their petioles and peduncles elongated to reach the surface. The leaves of small plants lie close to the ground and the flowering stems are short. Seeds dispersed by plants in cultivation are constant in character.
Aristotelia fruticosa Hook. f. var. rigidula var. nov.
Frutex arte divaricatus, c. 1 m. altus; ramuli fusci, apicibus versus pubescentes denique cornei. Folia adulta 2–4—fasciculata, 1 cm. longa, 5–8 mm. lata, late oblonga vel obovata, nonnunquam fere orbiculata, integra, brevissime petiolata. Flores masculi 3–6 racemulose aggregati, pedicellis abbreviatis. Flores feminei solitarii, bracteis, 2–4, lineari-lanceolatis praeditis.
A densely divaricating shrub to 1 m. or more tall; branchlets reddish brown, pubescent at the tips, short, strongly reflexed, tapering to thorn-like tips. Leaves in fascicles of 2–4 on short arrested branchlets, on juveniles or on adventitious shoots 2–3 cm. long, 1–1.5 cm. broad, ovate lanceolate or oblong lanceolate, irregularly and sharply serrate; adult leaves 1 cm. long, 5–8 mm. broad, broadly oblong or obovate, sometimes almost orbicular, entire or in shade occasionally obscurely sinuate or roughly serrate; petioles short, slender; blade thin, glabrous and shining above, lighter beneath
and the reticulation evident. Male flowers 3–6, 2 mm. diam., crowded on short, minutely pubescent, drooping racemes, bright pink or almost white; pedicels short, as long as the flowers, minutely pubescent; sepals 4, oblong, obtuse, pink or greenish, half the length of the petals; petals broadly obovate to almost orbicular, concave, irregular emarginate. Stamens 4–6, crowded on short filaments, shorter than the petals. Female flowers single, drooping, with 2–4 linear lanceolate bracts at the base. Ovary glabrous, conical, extended into a 2 lobed, pink style equalling the petals. Berries globose, 5 mm. diam., changing colour from the green state through white and red to ripen black. Seeds 2, semi-spherical, 2 mm. diam., black, reticulated.
Habitat: Exposed or stony slopes.
Type specimens from Flagstaff Hill near Dunedin, in the Herbarium Plant Research Bureau, Wellington.
Cheeseman's (1925–559) note “frequently solitary” regarding the flowers of Aristotelia fruticosa suggests male and female flowering specimens.
In the wetter districts of the South Island it is a more or less erect plant, or it may be stunted on exposed ridges, but never is it comparable in form with var. rigidula, of which we have specimens also from the head of the Otekaieke River, Dansy's Pass, Central Otago.
Lacking flowers or fruits the variety is difficult to distinguish from Coprosma crassifolia.
Aristotelia erecta Buch.
Cheeseman (1925–559) refers Buchanan's species to the synonymy of A. fruticosa, but from the description (1871–209) of its leaves, “2 in. to 2 ½ in. long,” it would appear to be one of the many forms of A. serrata x fruticosa.
Epilobium parviflorum sp. nov.
Herba parva pallide viridis, 10–20 cm. alta, parce ramosa, caulibus sanguineis inferne lignescentibus, e basi arcuata ascendentibus, minute bifariam pubescentibus.

Type specimen in the Herbarium Plant Research Bureau, Wellington, from the Wairoa Gorge, Nelson.
The much-branched woody character of this slender plant differs from all other of the endemic species. Flowers appear in a succession as the stems elongate and flowers and ripe fruits may be collected from a single stem.
Myosotis macrantha Hook. f. et Benth. var. diversa var. nov.
Foliis radicalibus 5–7 cm. longis, 1–1.5 cm. latis, obovatospathulatis, floribus intus albis vel ochroleucis, extus purpureis; corollae tubo 1.5 cm. longo, gracile, infundibuliforme distinguitur.

Type specimen from the Pelorus Valley, Nelson, in the Herbarium Plant Research Bureau, Wellington.
This is, in the main, the H. menziesii of Cheeseman's Manual (1906–512), and the comments of Cockayne and Allan (1927–25)
with regard to its status are significant, “We greatly doubt whether the species, as defined in the Manual, is Bentham's, which was based on material collected at Dusky Sound by Menzies.” The present authors' (1942–27) restriction of H. menzieii to the Fiord and part of the South Otago Botanical Districts left the very different Nelson-Marlborough plant without a name.
Hebe lycopodioides (Hook. f.) Ckn. et Allan var. patula var. nov.
Fruticulus typo similis sed parvior, c. 10 cm. altus, caulibus decumbentibus, ramis gracilibus, rt 2 mm. diam.

The authors were acquainted with the plant on the slopes of Mt. Technical, and Mr. W. B. Brockie has specimens in cultivation collected on various mountains from Lewis Pass, west of Hanmer, southward to Harper Pass at the head of the Hurunui River. He finds it to be the common and only form of the species throughout that range.

Type specimen from the Kepler Range, near Fowler Pass, head of the Freeman River, Lake Manapouri, in the Herbarium Plant Research Bureau, Wellington.
This species is common in its habitat and is easily mistaken for a depressed state of H. murrellii. It has, however, differently shaped and almost distichous leaves, few and larger flowers, and shorter stamens. We know of no other species with a similar paucity of flowers.
Veronica laxa Simpn. et Thomn.
Fowler Pass, Kepler Range, Otago. 800 m. alt.
Ourisia macrophylla Hook. f. var. robusta comb, nov. = O. robusta Col. in Trans. N.Z. Inst., xvii (1886) 246.
We are indebted to Mr. E. S. West, Napier, for plants collected at the Titiokura Saddle, between Napier and Taupo, which substantiate Colenso's observation of character differing from the plant of Mt. Egmont and elsewhere. The leaves are narrowed at the tip, the midrib and veining more prominent than in the type, the margins bluntly serrate rather than lobed, and the edges of the channelled petiole purplish. The lobes of the limb are closely placed, their upper surfaces white or pinkish, and their lower surfaces distinctly purplish, with the veining darker.
The variety is amply distinct, but too near O. macrophylla for more than varietal recognition.
In his later years Colenso no doubt described many trivial forms or epharmonic states of well-established species, but that phase of his work has been over emphasised. We are convinced that a re-examination of the plants he described would appreciably relieve the synonymy which obscures so much of his work.
Lagenophora barkeri T. Kirk var. multidentata var. nov.
A typo differt foliis 2–7 cm. longis, 1–1.5 cm. latis, obovatis vel obovato-spathulatis, obtusis, glabris vel pilis paucis brevibus; laminis sinuatis, vel arte irregulariterque leviter dentatis vel lobatis, lobis breviter apiculatis ciliolatisque.

Type specimen from the Upper Shag Valley, near Kyeburn, in the Herbarium Plant Research Bureau, Wellington.
A common grassland plant in the valleys of the Shag and Wai-taki Rivers and their tributaries, Lindis Pass, L. Pukaki, etc. The
irregularly margined, minutely pubescent, darkish green leaves, and the long, slender scapes are unlike those of any other of the other species.
Olearia crosby-smithiana Petrie.
Fowler Pass: Common on slopes below the steep drop from the summit to the western side.
Celmisia verbascifolia Hook. f.
Some Fowler Pass plants of this common Fiord species, growing luxuriantly on cleared flats in forest near Lake Minerva, had scapes 30 cm. or more long, subcorymbosely 6-flowered by long secondary scapes from the bracts. The primary scape was usually shorter and always much thicker than the branching secondaries.

Leaves shorter, =15 cm. long, broader, =1 mm., suddenly reduced to an apiculate tip, bronze green and the veins evident, rigid, more deeply channelled than those of the species, the margins not recurved.
Habitat: Low grassland.
Type specimen from Lake Man, above Amuri Pass, head of the Doubtful River, Hanmer, in the Herbarium Plant Research Bureau, Wellington.
We are acquainted with the variety at this habitat, where it was discovered by Mr. W. B. Brockie in 1935. The leaves of the Awatere Valley plant are gradually narrowed to the tip, and their margins are recurved. In both forms they are broadened to a hard, densely woolly base.
Celmisia sessiliflora Hook. f. var. exigua var. nov.
Speciei similis sed minor, foliis=8 mm. longis, 1 mm. latis; capitulorum pedunculis primum perbrevibus, capitulis, foliis occlusis denique elongatis.
Similar to the species but smaller. Leaves=8 mm. long, 1 mm. broad. Heads on short petioles, sunken amongst the leaves; petioles elongating in fruit.
Habitat: Common in sub-alpine grassland on mountains at the source of the Freeman River, Lake Manapouri; McKinnon Pass. Altitude 1000-1200 m.
Type specimen, from Fowler Pass, in the Herbarium Plant Research Bureau, Wellington.
The variety spreads into close flat patches in sub-alpine grassland in the manner of the species, and it has been confused with the densely branched, cushion-forming C. argentea.
Celmisia argentea T. Kirk.
By mistakes in identity this species has been recorded from stations that would suggest a wide but discontinuous distribution, and the various descriptions lack particulars of its growth habit. On Mt. Maungatua, the type habitat, Phyllachne colensoi and
Gaimardia setacea are its companion plants, and it forms very similar low and rounded but silvery grey cushions on moist peat at the raised fringes of sub-alpine bog. The many short, closely leafy branchlets are 1 cm. diam., sub-globose at the tip, closely compacted; the leaves numerous, 3 mm. long, 1 mm. broad at the base, subulate, acute, pubescent, with villous membranous sheaths as long as the blade.
Celmisia lanceolata Ckn.
Sub-alpine scrub and grassland on hills to the west of Fowler Pass, between Lake Manapouri and Bradshaw Sound.
This fine species, first discovered by Cockayne on the Long-wood Range, may range still further to the north and west in the Fiord Botanical District. Mr. W. A. Thomson informs us that it is common on the mountains to the west of Lake Manapouri.
Raoulia buchanani T. Kirk.
The specimens collected by Buchanan on Mt. Alta lacked flowers, and Cheeseman (1925—971) described them from specimens collected in other localities. “Heads small, hidden amongst the leaves at the tips of the branches.” The heads are 6 mm. diam., with dark crimson florets raised slightly above the densely compacted glaucous cushion.
Raoulia bryoides Hook. f.
The flower colour is not recorded, but plants collected from the Awatere Valley, Marlborough, have whitish florets.
