Cauline leaves few, bract-like, sessile or nearly so, approximate, smaller and less divided than the radical.

Scape moderately stout, about 8 cm. high, divided near the top into 3 or fewer branches, each bearing a single flower.

Flowers peduncled, 1 ½–2 cm. across, large for the size of the plant.

Sepals nearly as long as the petals, broad, obtuse, thin, pale, manynerved, sparsely villous on the outside.

Petals 10, bright yellow, rounded at the top and cuneately narrowed to the base, many-nerved; nectaries basal (apparently 3).

Stamens and pistils very numerous.

Ripe achenes not seen.

Hab.—Mount Balloon (Te Anau - Milford Track).

This species is named in honour of Miss B. E. Baughan, by whom it was collected as above. The material for its description, which was very scanty, was lent me by Mr. R. M. Laing, B.Sc., of Christchurch. The plant has its nearest ally in R. sericophyllus Hook, f., in which, however, the scapes are always 1–flowered.

2. Epilobium rostratum Cheesm. var. pubens var. nov.

Planta typo humilior magisque diffusa, caulibus foliis capsulisque valde pubescentibus.

More depressed and spreading than the type, with the stems, leaves, and capsules strongly pubescent.

– 266 –

Hab.—Dry ground in Awatere Valley (Marlborough), and bed of Robinson River, in same district.

Collected by Dr. L. Cockayne, F.R.S., F.L.S., 11th January, 1912, who has supplied me with specimens.

Hob.—Queenstown Hill, Lake County.

This species, which I am pleased to name after its discoverer, was collected by Mr. William Willcox, Director of the Queenstown Park. It is somewhat closely allied to O. oleifolia T. Kirk. Dr. L. Cockayne, F.R.S., F.L.S., of Christchurch, kindly lent me the material for this description. As it was very scanty, allowance must be made for possible inaccuracies, especially in my account of the habit of the plant, which is still but little known.

5. Celmisia intermedia sp. nov.

Caules a basi ± ramosi, primo plerumque prostrati demum erecti v. ascendentes, in aetate reliquiis vaginarum foliorumque demortuorum persistentibus vestiti, graciles.

Folia conferta, imbricata, anguste obovato- v. elliptico.-spathulata, ± 1 ½ cm. longa, 6–10 mm. lata, subacuta, tenuia, in partem petiolarem perangustam contracta, denique in vaginam latam amplectentem striatam glabram ampliata, infra (costa excepta) tomento candido arcte appresso vestita, supra glabra viscidaque v. tenui pubescentiae subtomentosae argenteae pellicula praedita, a marginibus apiceque minute et subremote dentata, venis haud distinctis.

Scape in ramulis singulis plerumque 1 (rarius 2), axillares, prope summos ramulos inserti, 7–15 cm. longi, gracillimi, parce laxeque tomentosi; bracteae subdistantes, lineari-subulatae.

– 268 –

or covered with a delicate pellicle of silvery subtomentose pubescence; minutely and rather distantly toothed along the edges and at the tip; veins indistinct.

Scapes usually solitary on the branchlets, springing from the axils of the subterminal leaves, 7–15 cm. long, very slender, sparingly and loosely tomentose; bracts rather distant, linear-subulate.

Heads 1–1 ½ cm. across; involucral bracts linear-subulate, delicately glandular-pubescent, the inner longer.

Achenes linear, sparsely pubescent, a little shorter than the pappus.

Hab.—Mount Frederic, 3,400 ft. (P. G. Morgan)! Arthur's Pass, 3,000 ft., D. P.; mountains near Westport (Townson)! Mount Greenland, Westland (Dr. L. Cockayne)!

In his “Manual of the New Zealand Flora” Mr. Cheeseman has included this plant in var. petiolata T. Kirk of Hooker's C. incana. It is doubtless connected with that species by forms more or less intermediate, but it possesses a number of distinctive characters that remain constant over wide areas on the western side of the South Island, and it therefore appears to me best to recognize it as a distinct species, a course that Dr. Cockayne has already suggested. Mr. Kirk's variety, the type of which was collected by myself, is closer to typical C. incana than is the widely spread form described above. The species forms a transition between Hooker's species C. incana and C. discolor.

6. Helichrysum (Leucogenes) Grahami sp. nov.

Caules numerosi a radice longo crasso ligneo emi si, simplices v. parce divisi, subgraciles (cum foliis 3–4 mm. lati), molles, flexiles, 10–15 cm. alti.

Flores numerosi, feminei 1-seriati; corolla perangusta, basi subito tumida, apicem versus leviter expansa; pappi setae paucae, barbellatae, apicem versus leviter incrassatae.

Achenium parce pilosum.

Stems numerous, from the top of a long stout woody root, simple or sparingly branched, slender (with the leaves on, 3–4 mm. across), soft and pliant, 10–15 cm. high.

Leaves closely imbricating in several series, appressed or slightly spreading at the tips, sessile by a broad base, shortly lanceolate, ± 5 mm. long, subacute, everywhere densely clothed with loose greyish-white cottony tomentum, a few of he uppermost longer and broader, but not exceeding the heads.

Heads in capitate fascicles of 2–5, terminal, sessile, each ± 2 mm. across; involucral bracts in 3 series, very pale, shining, scarious, linear-oblong, subacute, scarcely radiating, the outer sparingly tomentose on the backs.

Florets numerous, female in 1 series; corolla abruptly swollen at the base, very narrow, slightly dilated above; pappus hairs few, slender, bar-bellate, slightly thickened above.

Achene sparsely papillose.

– 269 –

Hab.—In clefts of rocks on Sebastopol Ridge, Sealey Range, Hooker Valley, Mount Cook. Flowers in February and March.

This interesting addition to the chasmophytic plants of our rocky mountain-slopes was discovered by Mr. Peter Graham, Chief Guide at the. Mount Cook Hermitage. I am deeply indebted to him for a fine specimen, and am pleased to associate his name with so remarkable a plant. In some respects it is intermediate between Helichrysum Vaill. and Leucogenes Beau verd. Fuller material is needed to settle its exact position.

7. Raoulia cinerea sp. nov.

Caules ramosi, serpentes, a latere inferiore complures longos radices emittentes, crassiusculi; rami breves prostrati v. ascendentes.

Involucri squamae 2–3 seriatae, folia suprema haud excedentes, scariosoe, subflavidae, acutae, dorso parce tomentosae, interiores glabrae haud radiatae.

Flores in capitulo utroque circa 15.

Pappi setae graciles, nec barbellatae nec apice incrassatae.

Achenium lineari-oblongum, glabrum.

Stems branched, forming dead-looking patches, creeping and sending down numerous long slender roots from the underside, with the leaves rather stout; branches short, prostrate or ascending.

Heads terminating the branches and sunk among the uppermost leaves, about 5 mm. across; involucral bracts in 2 or 3 series, not exceeding the uppermost leaves, scarious, yellowish, acute, sparingly tomentose on the backs, the innermost glabrous not radiating.

Florets about 15 in each head.

Pappus hairs few, slender, not barbellate or thickened at the tips.

Achene linear-oblong, glabrous.

Hab.—Shingle Peak, Upper Awatere (Marlborough), 5,000 ft.

This most distinct species was collected by Dr. L. Cockayne, F.R.S., F.L.S., and Mr. S. G. Mowat, in January and February, 1912, to whom I am greatly indebted for specimens.

Radical leaves few, linear-oblong, slightly narrowed below, 4 cm. long, 5–6 mm. broad, obtuse, slightly recurved when dry, above densely clothed with rather long stiff whitish hairs that project beyond the edge all round, below less densely pilose with stiff hairs commonly reflexed; cauline sessile, close-set, crowded at the tops of the stems, similar to the radical but flatter shorter and narrower, about 2 cm. long and 4 mm. broad.

Racemes sunk among the uppermost leaves, very short, densely and delicately pilose, the flowers strongly congested.

Calyx more or less turbinate, clothed with long delicate straight and hooked bristle-like hairs, 5-lobed to below the middle, lobes subulate-oblong.

Corolla purplish (when dried), barely equalling the calyx, with a wide tube cut for one-third its length into 5 rounded lobes; scales very obscure (or absent?).

Stamens 5, almost sessile, rather long, reaching to the mouth of the corolla-tube but not beyond.

Style very slender, as long as the stamens, subcapitate.

Hab.—Shingle Range, Upper Awatere (Marlborough), 5,000 ft. Flowers December and January.

This well-marked species was collected by Dr. L. Cockayne, F.R.S., F.L.S., to whom I am indebted for specimens. The flowers examined are perhaps not fully developed, and may elongate somewhat when more mature. The anthers are, however, fully formed.

9. Gentiana tenuifolia sp. nov.

Caules 30–40 cm. alti, 2–3 mm. in diam., subteretes.

Folia radicalia numerosa, conferta, majuscula, anguste obovato-spathulata, 8–14 cm. longa, 2–3 ½ cm. lata, tenuia, obtusa v. subacuta, nervis 3–5 arcuatis venisque reticulatis manifestis.

– 271 –

Flowers rather few, in bracteate umbels terminating the main axis and the lateral peduncles (12 cm. long or less), ultimate pedicels 4–5 mm. long.

Calyx about 1 cm. long, cut for three-fourths its length into 4 linearsubulate 1-nerved lobes.

Corolla (in the specimens examined not fully expanded) white, somewhat longer than the calyx, deeply divided into 5 acute lobes.

Stamens half as long as the stout pistil.

Hob.—Lyell Creek, 1,000 ft., and Boundary Peak, near edge of scrub (south-west Nelson), 4,000 ft.

Mr. William Townson has kindly lent me his specimens of this plant, which he collected in the two localities mentioned above. He did not succeed in finding plants with the flowers expanded, but the stamens in the partially closed corolla have already shed their pollen. The leaves are unusually large and thin, and the intervals between the cauline leaves remarkably long. I have what may be the same plant from Mount Blairich, collected by the late Henry J. Matthews, but the specimens are too immature to warrant a decided opinion.

10. Convolvulus fracto-saxosa sp. nov.

Perennis, ubique pubescentia cinerea copiose vestita.

Rhizoma gracile radices tenues ramosos subhorizontales edens.

Caules simplices v. a basi divisi, procumbentes.

Flores axillares, solitarii, longe pedunculati.

Sepala inaequalia, late obovata, ± crenata.

Corolla alba, 2 cm. in diam.

Perennial, everywhere densely clothed with copious rather long slategrey pubescence.

Rootstock rather slender, fleshy, sending off thin branching nearly horizontal roots.

Stems slender, simple or branched from the base, prostrate or trailing, leafy, 8–16 cm. long.

Leaves petiolate, thin, trimorphic, variable in size and shape; primary (earliest) shortly petiolate with small semicircular or broadly ovate or ovate-cordate entire or sinuate blades about ½ cm. long and 1 cm. broad; intermediate with longer petioles and blades 1 ¼ cm. long, ¾ cm. broad, divided into 3 oblong obtuse entire or slightly sinuate lobes (the terminal lobe at right angles to and longer than the two lateral lobes); the ordinary form on longer petioles (3–4 ½ cm.) with subhastately tripartite blades 2–3 cm. long and 1–1 ¾ cm. broad (at the base), the terminal division long narrow obtuse or subacute, more or less chanelled above, with obscure midrib, the basal divisions subtriangular narrow at the point of origin and widening outwards, sometimes entire, but usually deeply cut in front into 2 widely diverging subacute lobes.

Flowers axillary, solitary; peduncles as long as the petioles, thickened above and with 2 linear short bracts a little way below the flower.

– 272 –

Sepals 5, the outer 3 larger, broadly obovate and more or less crenate, 5 mm. long.

Corolla white, 2 cm. in diameter.

Hab.—Inland Kaikouras, Awatere Basin, on shingle-slip.

Collected by Dr. L. Cockayne, F.R.S., F.L.S., who has supplied the material for this description. The species is no doubt closely related to C. erubescens Sims, but the remarkable form and constant general character of the ordinary leaves, and the conspicuous grey pubescence, mark it off clearly enough.

11. Veronica Willcoxii sp. nov.

Frutex erectus, ramosus, glaber, ad 8 dcm. altus; ramis strictis.

Folia decussata, imbricata, basi connata, anguste obovata, 10–12 mm. longa, 4–6 mm. lata, subacuta, in basim sessilem latiusculum gradatim angustata, rigida, coriacea; supra concava, valde vernicosa nitidaque; subtus glaucescentia ac puncticulata, carinata, costa media fere excurrente.

Racemi 2–4, in axillis foliorum superiorum dispositi, 2–3 cm. longi, densiflori; floribus breviter pedunculatis.

Bracteae tenues, lanceolatae, ad basim calycis pertinentes.

Capsula late elliptica, obtusa, calycis lobis duplo longior, 5 mm. longa, 3 ½ mm. lata.

A compact erect much branched shrub, 8 dcm. high or less.

Branches rather stout, strict, leafy, glabrous or sparsely bifariously pilose towards the tips, below closely ringed by the scars of fallen leaves, dark brown.

Racemes 2–4 in the axils of the uppermost leaves, 2–3 cm. long, denseflowered; rhachis glabrous or slightly puberulous, dark brown, the lower part naked.

Bracts thin, lanceolate or lanceolate-subulate, reaching to the base of the calyx.

Flowers shortly peduncled, apparently white. Calyx deeply cut into 4 thin obovate scarious lobes ciliate at the margin, about half as long as the corolla-tube. Tube of corolla rather short and wide, limb broadly 4-lobed.

Stamens and style long exserted.

Capsule broadly elliptic, twice as long as the calyx or more, compressed above, less so below, 5 mm. long, 3 ½ mm. broad.

Hob.—Routeburn Valley, near Lake Harris, 3,000 ft. W. Willcox! and D. P.

I take this to be a very distinct species, more closely related to V. decumbens Cheesm. than to any other. It has been in cultivation for a number of years, but its wild habitat was unknown till early in 1911. I have not seen wild specimens in flower, but the cultivated plant is certainly identical with that found sparingly in the Upper Routeburn Valley.

– 273 –

12. Veronica Armstrongii T. Kirk var. annulata var. nov.

Folia opposita, connata, quam in typo breviora, annulos angustos cupuliformes erectos ramis appressos formantia; foliorum apicibus mere truncatis, parce ciliolatis; calycis segmentis integerrimis.

Planta valde depressa, ramulis quam in typo paucioribus brevioribusque instructa.

Leaves opposite, connate, shorter than in the type, forming narrow cup-like erect rings appressed but not adnate to the branches, the tips quite truncate, with a slight depression at the junction of the connate leaves.

Calyx-segments entire. The whole plant depressed and with fewer and shorter branchlets than in the type.

Hob.—Rock face of northern slope of Takitimu Mountains, Southland, at 2,950 ft. altitude.

Collected by Dr. L. Cockayne, F.R.S., F.L.S., 13th March, 1912, who has supplied me with material for the above description.

In V. Armstrongii the connate leaves form a slightly dilated cup round the branchlets, while the leaves present a small median cusp. Its most southerly known habitat is the north-east face of the Ku ow Mountains (Waitaki County). Mr. Cheeseman's herbarium contains several specimens collected there by myself. Dr. Cockayne would rather regard the plant as a distinct species.

13. Veronica Grahami sp. nov.

Capsula calycis lobis aequilonga, valde compressa, late obcordata, glabra, 5 mm. lata altaque.

A depressed, tufted, sparingly branched herb.

Stems slender, at first prostrate, then erect, as are the branches, 15–20 cm. long, when young more or less pubescent-pilose, in age glabrous and marked by rather distant scars of fallen leaves.

Leaves in opposite pairs, close-set and usually overlapping, sessile by a broad base, coriaceous, ovate-cuneate, 7 mm. long by 5 mm. broad, at the top rounded and cut in crenate fashion into 5 short obtuse lobes, the middle one much the widest, everywhere sparsely pubescent with very short stiff moderately appressed whitish hairs, reddish-brown when dried, nerves obscure.

Flowers solitary, in the axils of the upper leaves.

Calyx 4-partite; lobes erect, linear, thin, sparsely pubescent-pilose.

Corolla and stamens not seen.

Capsule as long as the calyx-lobes, 5 mm. broad and high, much compressed, broadly obcordate, glabrous.

– 274 –

Hab.—Cracks of rocks near Copeland Pass, Mount Cook, 7,000 ft.

This very distinct species was forwarded to me by Mr. Peter Graham, Chief Guide at the Mount Cook Hermitage. Its nearest ally is probably V. Muelleri Buchanan, a species that is not well known. It is to be hoped that its discoverer may soon be able to secure flowering specimens of this interesting find.

14. Danthonia oreophila Petrie var. elata var. nov.

Planta typo permulto altior crassiorque, valde densos caespites formans.

Culmi 35–55 cm. alti, crassiusculi, subrubentes.

A much taller, stouter, and more tufted plant than the type. Culms 35–55 cm. high, rather stout, reddish.

Leaves 25–30 cm. long, with broad coriaceous sheathe.

Panicle larger and with longer branches; spikelets larger and reddish-yellow while young.

Hab.—Sealey Range, Tasman Valley; abundant from 4,000 ft. to 5,000 ft.

The typical form occurs in fair quantity on the same slopes. The reddish tint is very conspicuous, and is to some extent shared by the leaves. Flowers late January and early February.

15. Poa Cockayniana sp. nov.

Species Poae dipsaceae (mihi) subsimilis; folia angustiora, firmiora, complicata; paniculi rami rhachisque scabridi; spiculae minores, magis compressae, obovato-cuneatae; glumae vacuae spiculas 2–3 florigeras paene aequantes; glumae floriferae tenuiter scaberulae; folia juniora supra plerumque ± pubescentia.

Perennial, culms tufted, more or less branched at the base, rather stiff, slender, erect, terete, smooth, glabrous, 35–50 cm. long, generally 2–3-noded. the nodes narrow and the topmost a little more than half-way up the culm.

Leaves 30–40 cm. long, shorter than the culms; sheaths loose, thin, complicate, strongly striate or fluted, forming about ⅓ the entire length of the leaves; blades rather stiff, complicate (rarely flattened), narrow, gradually tapering to fine tips, glabrous or finely pubescent (when young), delicately striate above and more strongly below; midrib prominent; ligule a very short broad band more or less coarsely jagged.

Panicle ovate, 10–15 cm. long, 6–7 cm. broad, few-flowered; rhachis and branches scabrid; branches capillary, 2- rarely 3-nate, sparingly subdivided, the lower half naked, the upper with few rather distant pedicellate spikelets.

Spikelets 6 mm. long, compressed, narrow obovate-cuneate, 2–3-flowered; empty glumes nearly equal, only a little shorter than the spikelets (the upper glume almost equalling the flower it encloses), lanceolate, acute, membranous, 3-nerved, the upper part of the keel ciliate-scabrid; flowering-glumes oblong-lanceolate, obtuse and irregularly erose (rarely subacute and nearly entire), distinctly 5-nerved, the nerves vanishing below the top, delicately scaberulous, membranous, scarious at the edges and tip and with long cobwebby hairs at the base and reaching nearly half-way up the back; palea ¼ shorter than the flowering-glume, nerves ciliate.

Hab.–Banks of Rolleston River, Westland.

The specimens, kindly sent me for identification, were collected by Dr. L. Cockayne, F.R.S., F.L.S., late in the season, and are all considerably past flower. He mentions that the grass has a somewhat wide distribution in the higher valleys of the western side of the South Island. For years past Dr. Cockayne has collected native grasses with unwearied zeal and great discrimination, and well deserves to have his name associated with this discovery.

16. Poa Guthrie-Smithiana sp. nov.

Stamina palea circa partem tertiam breviora.

Culms densely tufted, below prostrate or creeping, very slender, manynoded, giving off from the nodes closely placed slender flaccid intravaginal. leafy and flower-bearing branches 15–30 cm. long.

Leaves rather shorter than the culms, narrow-linear, complicate, smooth, glabrous, obsoletely nerved, 12–20 cm. long; sheaths broad, open, thin, striate, about ⅓ as long as the blades; ligule thin, short, acute, much broader than the blade.

Panicle very narrow, erect, green, 5–10 cm. long; rhachis slender, smooth, striate; branches 3–5 verticillate, short slender, erect, delicately scabrid, naked below, bearing 3–5 pedicellate spikelets.

Spikelets green, ovate, 6 mm. long, 2–4-flowered.

Empty glumes unequal, about ⅓ as long as the spikelet, lanceolate, acute, glabrous, the lower 1- the upper faintly 3-nerved; flowering-glumes lanceolate, acute, keeled, green with white scarious edges, smooth, glabrous, 3-nerved (the median nerve slightly excurrent, the lateral vanishing below the top), with a few rather long hairs on the callus and at the back; palea green, nearly as long as the flowering-glume, 2-nerved, nerves delicately ciliate.

Stamens slender, about ⅓ as long as the palea.

Hab.–Herekopere Island, off Stewart Island.

Mr. Guthrie-Smith, of Tutira, kindly sent me some live tufts of this grass in the early summer of last year. The plants have grown well in my garden, and have lately come into flower. It is from these cultivated specimens that the above description has been drawn up. The species is allied to Poa ramosissima Hook. f. both in the habit of growth and in the form of the panicle. It appears to have economic possibilities of some value, but at present these cannot be accurately estimated.
