Hab. Ruahine Mountain-range, east side: Mr. H. Hill, 1894; Mr. E. W. Andrews, 1895.
Obs. This fine plant has close affinity with three other known species from the same alpine locality—viz., R. insignis, Hook.; R. ruahinicus, Col. (Trans. N.Z. Inst., vol. xviii., p. 256); and R. sychnopetala, Col. (Trans. N.Z. Inst., vol. xviii., p. 324, and vol. xxvi., p. 313)—but differing from them all in several characters, and particularly in its peculiar and striking shaggy carpels.
Order VII. Portulaceæ.

Hab. Ruahine Mountain-range: Mr. A. Olsen; 1895.
Obs. This species is near the only other known southern one (C. australasica), but differs in its scape being 2–3 flowered, in its very much larger calyx (a striking character), different-shaped anthers, and bifid instead of trifid stigma. Of C. australasica Hooker says, in first describing it (” Icones Plantarum,” tab. 293), “petalis calycem quadruplo superantibus” — which his plate, with dissections, clearly show; and Bentham, “sepals small orbicular, petals several times longer; style 3-cleft,” &c. (“Fl. Australiensis,” vol. i., p. 177).
Order XXVI. Droseracæ.
Genus 1. Drosera, Linn.

Hab. Ruahine Mountain-range: Mr. H. Hill, 1895; Mr. A. Olsen, 1895.
Obs. A species having affinity with D. arcturi, Hook., and D. polyneura, Col. (Trans. N.Z. Inst., vol. xxii., p. 460), but differing from both in several grave characters.
2. D. stylosa, sp. nov.
Plant slender, weak, suberect; stem 10in.-12in. high, dark-green, almost black (so also stem-leaves and -sepals), striate, slightly branched, 1–2 small branches near top, each bearing 2–3 leaves and a single terminal flower.

Anthers very small, suborbicular, white; stamens dark-coloured. Ovary ellipticglobose, dark-green. Seeds linear, acuminate, somewhat falcate, brownish.
Hab. Ruahine Mountain-range, east side : Mr. H. Hill; 1895.
Obs. A species very near to D. auriculata, Backhouse, but differing in its branched stem (in number and position of stem-leaves), in bracteolate raceme, in broad laciniate sepals, and in its very peculiar styles, these last being a most interesting and curious object under the microscope.
Order XXXVIII. Rubiaceæ.
Genus 1. Coprosma, Forst.
1. C. margarita, 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.]
A small low shrub; bark dark-coloured, purplish; branches very slender, erect, and drooping when in fruit (specimens 6in.-8in. long); branchlets numerous, rather close, opposite, short, filiform, somewhat angular, thickly clothed with short greyish hairs, strigosely pubescent. Leaves few, more numerous at tips of branchlets, linear, 9 lines long, 1/16in. wide, glabrous, green, acute and subacute, slightly falcate, recurved, tips callous, tapering at base; petioles very short, purple. Stipules small, deltoid - acuminate, acute, pilose, ciliolate.

Corolla small, infundibuliform, ⅛in. long, pale-yellow irregularly spotted with purple, 4-lobed; lobes subovate and sub-acute, spreading, margins purple; styles twice as long as tube, stout, very pubescent, obtuse, spreading. Fruits numerous, globular, 1/10in. diameter, white, shining, semitransparent, crowned with the minute calycine lobes. Seeds 2, suborbicular, plano-convex, 1/12in. diameter, whitish.
Hab. Ruahine Mountain-range, east side: Mr. A. Olsen; 1895.
Obs. A very distinct species of this rather difficult genus, and very handsome when in fruit; its little solitary, globose, white, shining fruits resembling pearls strung on its light feathery foliage (whence its specific name). At this season its appearance is most striking, further increased by the graceful drooping of its slender loaded branches. I regret not having seen its male flowers; indeed, my female specimens—in fruit and in early flower—are the result of two visits made during two seasons, autumn and spring, to the mountains.
Genus 2. Nertera, Banks and Solander.
1. N. montana, sp. nov.
A small low creeping succulent glabrous herb, rooting at nodes, 1in.-3in. high, branches numerous and very short. Leaves suborbicular, broader than long, apiculate, 1–2 lines diameter, concave, tapering, a few rather long weak white cilié at margins; these are flat, semitransparent, and jointed; petioles 1 line long. Flowers small, terminal on short branchlets, sessile, pale-greenish. Corolla, tube shorter than limb; lobes deltoid, subacute, spreading, subhyaline, pubescent within. Stamens spreading longer than styles; anthers exserted, suborbicular and cordate, yellow; styles 2, spreading, recurved. Ovary broadly ovoid, glabrous.

A minute low creeping herb, 3in.-4in. long, rooting at nodes, much branched; branches very short; subsucculent, glabrous, finely papillose; stems purple-splashed. Leaves very small, scarcely 1 ½ lines long, suborbicular-deltoid, tip subacute, pale-green with purple margins, stippled below; petioles as long as leaves. Flowers terminal, very small, sessile; corolla 1 line in diameter, greenish-yellow, 4-parted; lobes deltoid, acute, finely pubescent within; stamens 4, longer than lobes; anthers orbicular, yellow; stigmas 2, recurved, shorter than anthers; ovary oblong. Fruit globular, glabrous, shining, sessile, 1/10in. diameter, red. Seeds 2, oblong-ovoid, 1/20in. long, plano-convex, greyish-white.
Hab. Low wet spots on the sides of the mountain Tongariro, in the Taupo district : Mr. H. Hill; 1893.
Obs. This is an interesting little plant—a perfect gem—in its lustrous, lowly, humble beauty. I have succeeded in growing it, and therefore have been able to watch its minute development, and to note all its grave characters in its fresh
state, in confirmation of dried specimens brought away by Mr. Hill.
Order XXXIX. Compositæ.
Genus I. Olearia, Mœnch.

Hab. Hilly country near Lake Tutira, County of Wairoa, Hawke's Bay : Mr. Guthrie-Smith; 1895.
Obs. A species much resembling and having close affinity with the preceding one, O. consimilis, but differing in involucral scales; in the many-lobed lamina of its disk-florets, with their peculiar-coloured margins; in its very long style-arms; and in its spreading, reverted, shining, brown involucres after flowering, that give it a curious appearance.
3. O. aggregata, sp. nov.
A thickly-branched shrub, 5ft.-6ft. high; branchlets 1ft. or more long, very slender, simple, rarely forked, subangular; bark dark-red-brown, glabrous, much coarsely striate. Leaves few, distant, opposite, fascicled 6–8 together, forming very small lateral branchlets, oblong-lanceolate, 3–5 lines long, 1 ½ lines wide, not thick, petiolate, margins entire and slightly recurved; tips subacute, dark-green and glabrous above, densely pubescent below; hairs appressed, white shining with a reddish tint, flat, lanceolate, acute, centrally fixed; midrib showing full-length beneath, its hairs also being darker; petiole 1 line long, hairy; hairs reddish, glossy, and so the
young leaves. Flowers numerous, opposite, fascicled : (1) On main branches regularly distant, ¾in. apart, and terminal on very short lateral branchlets (or spurs), 4–6 together among leaves; (2) on branchlets much closer, 4–5-fascicled, covering branchlets. Heads small, campanulate, ¼in. long; peduncle 1 line long, hairy, bibracteate. Involucral scales oblong, very hairy especially on margins and tips, few in 3 rows, the outer smallest, middle broadest with a dark central line, inner longest and narrowest and more membranous. Florets few; of ray 6, lamina 4-nerved, tip truncate, 3-toothed; style very short, as long as tube, arms short, obtuse; of disk 5, tips of their lobes ciliolate. Pappus few, erect, white, much shorter than florets, densely scabrid, tips subacute. Achene small linear angular thickened upwards, dull-brown, glabrous.
Hab. In the Weber district, County of Patangata, between Dannevirke and the East Coast : Mr. H. Hill; November, 1895.
Obs. A truly handsome shrub, from the great regularity of its numerous and neat symmetrical heads of flowers in small knots or bunches on its slender branches. This species belongs naturally to the same sub-section as the two former ones, but is very distinct.
4. O. parvifolia, sp. nov.
A small bushy shrub of diffuse growth, 6ft.-8ft. high, with erect twiggy branches; branchlets slender, glabrous, angular, dark-red, striate. Leaves and flowers produced together in small knots or bunches, 5–7 lines apart, opposite; leaves few, 3–4–6 together fascicled, very small, 1 ½-2 ½ lines long, sub-obovate tapering to base, tip obtuse and rounded, glabrous and dark-green above (sometimes hairy, hairs substrigose adpressed), densely pubescent below, hairs white (reddish in young leaves), shining, short, appressed; midrib lower half prominent underneath; petiole 1–1 ½ lines long. Heads 3–5. together (sometimes solitary), narrow campanulate, sub 2 ½ lines long, patent, spreading, axillary among leaves; peduncles slender, 2 lines long, hairy. Involucral scales hairy, in three rows; the outer 2–3–5 thickish, ovate, short, bract-like, dark-coloured (may be termed bracts, but they adjoin the other scales proper, and close round the head with them); the inner thin, green, shining, sub-linear-lanceolate, concave; tips acute and thickly woolly-ciliolate. Florets few, of disk and of ray equal in number, usually 4 of each, sometimes 5; ray, lamina small narrow pale-brown, tube slightly hairy, style two-thirds length of lamina, arms spreading, acuminate subacute; disk florets longest, much exserted, dark-brown, tube hairy, tips of lobes pubescent, anthers largely exserted
their tips very acuminate pungent, pale; stigmas large, rough, bristly, dark-red, tips acute. Pappus few, white, erect, scaberulous, shorter than disk-florets. Achene small linear terete, thickest at top, glabrous.
Hab. In low damp grounds, and on margins of watercourses, South Norsewood, County of Waipawa : Mr. A. Olsen; 1894–95. (Also, in former years, but barren : W. C.)
Obs. A species near to O. virgata, Hook.
Genus 17. Senecio, Linn.
1. S. rufiglandulosis, sp. nov.
Annual. Herb stout, erect, simple, glabrous, 2ft.-3ft. high; stem thick, ½in. diameter, subangular, hard below but not woody.

Hab. East sides of Ruahine Mountain - range, about 3,000ft.-4,000ft. altitude, on margins of watercourses, and also on dry stony spots: Mr. A. Olsen; 1894–95.
Obs. This fine herb has some affinity with S. glastifolius, Hook. fil.
Order XLII. Ericeæ.
Genus 1. Gaultheria, Linn.
1. G. glandulosa, sp. nov.
Shrub glabrous (specimens 5in. long, terminating in 3–6 branchlets, each 2in. long, and nearly alike); bark pale, muricated with small red and black callous points, the young branchlets having a single long black flat hair-like scale, acuminate and strigose, appressed upwards from each dot.

Hab. Ruahine Mountain-range, east side : Mr. H. Hill, 1894; Mr. E. W. Andrews, 1895.
Obs. A truly handsome and neat species, differing considerably from all known ones, yet having close affinity with G. subcorymbosa, Col. (Trans. N.Z. Inst., vol. xxii., p. 476).
Genus 3. Cyathodes, Br.
1. C articulata, sp. nov.
A (small ?) glabrous shrub; branch (specimen) 4in. long, slender, woody, bearing several very short branchlets 1in. long, bark greyish. Leaves suberect, close, decussate, imbricate, linear acuminate a little broader at base, 3 ½ lines long sub ½ line wide tapering into a long callous acute tip, thickish,
margins recurved entire; pale-dull-green above and somewhat glossy; paler below and 4-nerved, nerves white; petiole short, stout, broad, flattish, articulated to a little circular knob in the branchlet. Flowers terininal on the branchlets, 5–7 together forming small heads, pale-reddish or fawn colour; peduncles short, bearing small suborbicular bracts; calycine lobes or bracteoles larger, broadly ovate obtuse, pinkish, margins thin, minutely ciliolate at tips; corolla tubular sub 3 lines long veined; lobes 5, small ovate acute, glabrous not bearded; tube slightly hairy within; anthers adnate opposite angles of lobes, slightly exserted, linear, emarginate both ends, dark-brown; style erect, nearly as long as tube, slightly hairy below; stigma simple; ovary densely hairy; hairs appressed, pure white. Hypogenous scales, small, orbicular.
Hab. Hills in the interior, west of Napier; 1895.
Obs. I Of this plant I received only a solitary specimen (among those of other plants), apparently casually gathered in passing as of no great consequence; all the little branchlets on it were very similar and perfect.
II. I place it here under Cyathodes (not having seen its fruit) mainly owing to the lobes of the corolla being glabrous and the leaves so very pungent. A curious feature is the knobbed articulations of its branchlets for its leaves.
Genus 5. Pentachondra, Br.
1. P. rubra, sp. nov.
A low shrub 3in.-4in. high, ascending, erect, much branched; branchlets short, 1in.-2in. long, bracteate; bracts numerous, imbricate, sessile, red-brown, ovate, obtuse, striate, small at base of branchlets increasing in size upwards, 1 line long at top. Leaves close-set, erect, narrow ovate (the uppermost linear-ovate), ¼in. long, 1/15in. broad, obtuse, tips callous, glabrous, concave, margins finely ciliolate, 3–5 nerved below, pale-dull-green; petiolate, petioles ½ line long, red, striate, stout, flattish. Flowers few, solitary, terminal, red; tube cylindrical, 3 lines long, glabrous and shining on outside, slightly hairy within; lobes 5, sub 1 line long, narrow linear-ovate subacute, recurved, spreading, densely bearded, hairs red; bracteoles broadly ovate, obtuse, much ciliate. Anthers linear, subclauate, widest at top, subacute at base; style erect, stigma capitate. Disk-scales, tips truncate. Fruit obovate, ½in. long, red, style persistent. Nuts 8, subreniform, gibbous, red, muricatulate-rugose.
Hab. Ruahine Mountain - range : Mr. E. W. Andrews; 1895.
Obs. This plant, having 8 pyrenes in its fruit, does not agree with its generic name, nor with Bentham's statement respecting the genus—viz., “with 5 distinct pyrenes, or fewer
by abortion” (Fl. Austral., vol. iv., p. 163). Yet Hooker says of it, “Drupe of 5 or more small 1-seeded nuts” (Handbook N.Z. Fl., p. 178). In other respects it agrees with the genus, and it may, with the next plant hereunder described, serve to unite those two nearly-allied genera.
Genus* Trochocarpa, Br.
1. T. novœ-zealandiœ, sp. nov.
A low bushy shrub, 1 ½in.-2in. high, much branched, glabrous; branches short; stems woody, slender, blackish. Leaves numerous, close, imbricate and spreading, lanceolate, 1 ½ lines long, ½ line wide, tip subacute-obtuse, 3–5-nerved below, rather thickish, margins entire; dark-purplish-green; petioles rather stout, ½ line long, red; margins of young leaves toward apex minutely ciliolate (sub lens). Flowers few, solitary, terminal and axillary on tips of branchlets, sessile. Sepals 5, ovate-acuminate, tips obtuse, margins finely ciliolate; 2 broad bracteoles below calyx, and smaller roundish ones outside. Corolla subcylindrical, 2 lines long, valvate in bud, tip acute, white with pink tips on outside; tube slightly hairy half-way down; lobes 5, equal, acute, much bearded within, and 2-nerved from base. Anthers linear-oblong, brown, adnate, close to angle-bases of lobes; style stout, erect; stigma capitate, papillose. Fruit red, globular, shining, 2 lines diameter, pulpy, style persistent. Seeds 9, yellow, oblong, plano-convex.
Hab. Summits Ruahine Mountain-range, east side: Mr. A. Olsen; January, 1895.
Obs. It is not without some doubt that I place this neat little plant under this endemic Australian genus. It has much of the common appearance (prima facie) of a Pentachondra, but its fruit is strikingly different, also its pyrenes, and its corolla-lobes are not so densely bearded.
Genus 8. Dracophyllum, Lab.

Hab. At Kuripapango, on the River Ngaruroro, in the hilly interior, County of Hawke's Bay : Mr. H. Hill; 1894.
Obs. I. A very graceful flowering-shrub, its flowers presenting a peculiar neat and striking star-like appearance. It will range naturally near to V. colensoi, Hook., and V. darwiniana, Col. (Trans. N.Z. Inst., vol. xxv., p. 331). In drying, the leaves lose much of their dark-green colour above, and become glaucescent.
II. Mr. Hill brought away living plants, which have done well in his garden at Napier.

Leaves rather close, opposite, subsecund, sub-rhombic-orbicular, 4 lines diameter, deeply cut, serrate, 3 teeth on the side (sometimes only 2), tip obtuse and subacute, glabrous, dark-green, thickish; petiole 1 line long, stout, canaliculate, glabrous, edges pink. Flowers in slender erect axillary opposite peduncles 4in.-5in. high, the lower half (or more) naked, finely and closely pubescent (as also pedicels); flowers 15–20, alternate, rather distant, patent; pedicels 4–5 lines long, very slender, with a single sessile bract at the base (in one specimen 3 together subfascicled, with 3 bracts), bracts ovate obtuse 1/10in. long, the lowest pair 2 lines long (rather large for so small a plant), glabrous, margined, margin ciliolate. Sepals large, rhombic-ovate, obtuse, glabrous, thick, the apical portion of margins glandular-ciliolate. Corolla small, sub 3 lines long; tube very short; lobes 4, 3 of them orbicular, 1 (the lower) oblong, tip rounded entire, conniving, white with a pink throat and a few faint pinkish dashes. Stamens inclosed, shorter than lobes; anthers cordate obtuse;
style long, slender, flexuous, persistent; stigma simple. Capsule didymous, subpyriform, turgid, nearly twice as long as calyx (one specimen tri-celled). Seeds numerous, broadly elliptic-obovate, slightly turgid, dull-yellowish.
Hab. Ruahine Mountain-range, east side: Mr. A. Olsen; 1894–95.
Obs. I. The affinities of this neat little species are with V. bidwillii and V. lyallii, differing, however, from both in several characters.
II. Named after its discoverer, Mr. A. Olsen, of South Norsewood, a zealous collector and lover of plants, as many of them detected by him and described by me in this and in several preceding volumes of the “Transactions of the New Zealand Institute” bear ample witness. Of this genus, this species, with others, and many other plants from the mountain-ranges, flourish admirably in his well-stocked garden, the proximity to the mountain and its altitude being so suitable.
3. V. marginata, sp. nov.
A small shrub(?) (two specimens received by post); young branchlets 6in. long, simple, leafy alike throughout, bark pale-green, densely pubescent. Leaves decussate, spreading not crowded, 3 lines apart, broadly lanceolate, lin. long, 4 lines wide, tips acute produced, bases abrupt subtruncate, chartaceous, bright-green on both sides, glabrous, not flat, slightly revolute; margins entire, hairy, their extreme lateral edges minutely and thickly pubescent, hairs greyish; midrib sunk and finely pubescent above, very prominent below, excurrent, thickened and subscaberulous at tip; petioles 1 line long, stout, broad, glabrous, their bases half-clasping and semi-connate. Flowers rather numerous, terminal in small close corymbs 1 ½in.-2in. diameter, also axillary and subterminal in short deltoid distichous loose racemes, 1 ½in. long and 1in. wide at base, 5-jugate; pedicels patent, 1 ½ lines long, glabrous (sometimes finely but thickly puberulent), each with a small linear-ovate bract at base minutely ciliolate (also sepals). Sepals 4, large, half as long as capsule, ovate-acute, spreading. Corolla large, sub ½in. diameter, tube, very short or 0, throat wide; lobes 4, suborbicular, entire, the lowermost one only a little smaller, largely veined; colour white slightly dashed with lilac. Stamens included, stout; anthers cordate, obtuse, dark-purple. Style 2 lines long, slender, curved; stigma small, simple. Capsule (immature) slightly inflated, broadly ovoid, 3 lines long. Seeds oblong-obovoid, turgid, glabrous, pale.
Hab. From garden of Mr. A. Wall, Porirua, near Wellington (per Mr. R. C. Harding); 1895.
Obs. A very distinct, striking, and graceful species, differing largely from all others known to me, but having some affinity with V. elliptica, V. benthami, V. lœvis, and V. buxifolia. Its large flowers without tube (which makes them fugacious), 4-fid calyx with sepals large and sharply acute, elegant-shaped and symmetrically-placed leaves with their curious puberulous margins and produced tips, make the plant an attractive and pleasing object.
Order LXVII. Thymeleæ.
Genus 1. Pimelea, Banks and Solander.

Hab. Ruahine Mountain-range : Mr. H. Hill; 1895.
Obs. A species having close affinity with P. stylosa, Col. (Trans. N.Z. Inst., vol. xx., p. 205), but of more robust habit, erect and simple, possessing much smaller leaves and flowers, with much longer white hairs, style included, &c.
2. P. dasyantha, sp. nov.
Shrub low, bushy, suberect, 12in.-15in. high, much branched; bark brown, striate; branches, leaves beneath, and flowers densely strigosely hairy; hairs very long, acute, pure white.

Hab. On stony dry ridges near the River Waimataa, County of Patangata (the provincial boundary between Hawke's Bay and Wellington) : Mr. H. Sill; November, 1895.
Obs. I. On one of the branchlets, directly under the largest head of flowers and entirely concealed by it, I found two young branchlets a few lines in length, full leafy; showing that, shortly, that terminal head of flowers would become axillary in the fork occasioned by those two branchlets; and, further, in looking over the specimens I found the dead remains of receptacles of flowers in the axils of the old branches, confirming the same. I had, however, noticed that peculiar character before in P. dichotoma, a much larger species (Trans. N.Z. Inst., vol. xxii., p. 485).
II. This species will rank near to P. arenaria, A. Cunn., which, prima facie, it much resembles.
Class II. Monocotyledons.

Hab. Ruahine Mountain-range, east side: Mr. A. Olsen; 1894.
Obs. I have only received two specimens of this little plant, and they are very similar; unfortunately, though whole and perfect, they have been pressed very much in drying, so
that it has been a difficult matter to ascertain correctly their finer internal construction, on which so much depends, and I have only dissected one of them.

Order VII. Liliacæ
Genus 5. Astelia, Banks and Solander.
1. A. minima, sp. nov.
Plant very small, tufted; rootstock not woody, coalescent, softish, 3in. (et alt.) long. Leaves (5) linear, 11/2in. 11/2in. long 1 ½ lines broad, tips acuminate, acute, margins recurved, midrib very prominent below, scurfy with long white shining irregular scaly hairs above (also the scape, pedicels, and flowers), but glabrous below and nerved, their bases thickly covered with long silky white acuminate scales, and the young leaves densely margined with reddish shining scales.

Hab. Ruahine Mountain-range, east side : Mr. H. Hill, 1895; Mr. E. W. Andrews, 1895.
Obs. This is another small mountain species, allied to A. linearis, Hook., of the same mountain-range (and also of the Antarctic Islands, Auckland, and Campbell's); to A. alpina, Br., of Tasmania; and to A. pumila, Br., of Fuegia and the Falklands; but differing from them all. Of the specimens received, the female-flowered plants were much damaged and past flowering; sufficient, however, remained to show their great difference from their congeners.

Hab. Dry hills, altitude 1,000ft -3,000ft., Hawkston, County of Hawke's Bay : Mr. Thomas Hallett; 1894–95.
Obs. I. The affinities of this species are with D. racemosa R. Br. and D. penicillata (Arundo penicillata, Labill., Pl Nov. Holl., i., 26, tab. 34), but differing in several characters. Specimens received were obtained after flowering.
II. Mr. Hallett kindly informs me that this grass makes a close sward, but every plant only grows in its own simple tuft. Cattle and sheep are very fond of it, and crop it closely. It grows well during winter, and is about equal to most other grasses during summer for grazing purposes; and even while being closely grazed it perfects seed, owing to its habit of sending out many of its culms horizontally. A valuable grass on unploughable hills.
