Order 47.774 Apocyneæ.

Genus 1. Parsonsia, R. Brown.


Parsonsia macrocarpa,775 n.sp.

Plant, a shrub of very diffuse rambling growth, climbing over shrubs and bushes to the height of 12–14 feet; stem stout, ¾–1 inch diameter; branches pubescent with scattered white adpressed hairs; young branches densely tomentose; leaves papyraceous, opposite, elliptic-lanceolate (sometimes obovate), 2½ inches long (with a few smaller, 1–1½ inches), mucronate, pubescent, margins entire, slightly revolute, bright green above, pale yellowish-green below; midrib stout, tomentose on both sides, lateral veins opposite, nearly straight, parallel and regular, rather obscure; petioles slender, 5–6 lines long, slightly pubescent. [332] Flowers numerous, 12–00, terminal in long loose panicles and cymose-panicles, on long leafy axillary and opposite branchlets much longer than the leaves, scentless: calyx large, coloured dark pink, (and with pedicels and peduncle) densely velvety tomentose with light brown hairs; lobes acuminate acute, teeth about ½ line long, spreading, ciliated; the lobes lengthen much after flowering on the fruit: pedicels 2 lines long, each with one small bracteole: corolla pure white, urceolate, inflated, 3½–5 lines long, finely pubescent on the outside with very short scattered squarrose hairs; lobes small, scarcely 1 line long, subacute, subrevolute; throat constricted with a slightly raised corona: anthers wholly included below constriction. Follicles (immature and green) sub-cylindrical, tapering gradually to apex, points very obtuse, 8 inches long, 2½ lines in diameter, 8 lines circumference, striated longitudinally, umber-brown when dry, minutely strigose-pubescent with small scattered white adpressed hairs.

The nodal stipules or appendages, on the young long flagelliform densely tomentose branches (rami viminei) present a very curious appearance; they are opposite, erect, large, 3 lines long, subulate or linear with small dilated sub-leafy apices; at first, however, each one projects squarely out, about a line, at a right angle from the stem, with the outer point or elbow slightly dropping downwards, after the manner of a bracket corbel or drip; the whole possessing a peculiar quadrate and regular appearance.



Hab.—“Seventy-mile Bush,” Hawke’s Bay; thickets near banks of streams, 1876–1881: flowering in April, also in November, and possibly throughout the summer.

I had long known this plant in its leafing state, and had suspected—from its general tomentose appearance, and the regularity of the outline of its large leaves—that it might prove to be distinct from the two established New Zealand species, P. rosea and P. albiflora. Last autumn I was so fortunate as to obtain good flowering and fruiting specimens, which proved my conjecture to be correct, as it very widely differs, specifically, from both of those species,—more so indeed, than they do from each other. It is, however, allied to P. albiflora; and probably to an Australian species. It is a fine healthy-looking large and thickly-leaved species, and is evidently a fast grower.



Class II. Monocotyledons.

Order 1. Orchideæ.

Genus 4. Sarcochilus, Brown.


Sarcochilus breviscapa, 776 n. sp.

Plant epiphytical; roots stout, clasping, issuing from bases of leaves and forming large irregular masses, from which 4–8 plants grow: stems 6–10 lines high, compressed, subcylindrical, very stout, glabrous, purple, [333] covered by the imbricated sheathing bases of the leaves: leaves, usually 4–5 to a plant at a time, thick, glabrous, oblong or oblong-lanceolate, acute and pointletted, with a distinct mucro (almost like a short awn, so that each leaf has a vertical double-pointed apex), diminishing but slightly towards base, 1, 1½–2 inches long, 5–6 lines broad at middle, and 2–3 lines broad at base, sessile, sheathing, jointed immediately above clasping sheath, somewhat keeled, distichous, spreading, sub-falcate, dark-green spotted with purple, mid-rib below purple, 8-nerved longitudinally, nerves parallel and sparingly transversely netted, but only visible when leaf is dried: scape, slender, axillary in lower leaves, 4–8 lines long, (and with rhachis) green, closely spotted and blotched with purple; two solitary sheathing bracts, one at base, and one much larger and acuminate on one side in the middle: rhachis, 6–12 lines long, thickened.

Raceme 5–8-flowered, flowers not crowded: pedicels 2 lines long, alternate and scattered, purple striped, each having a single broadly ovate acute bract, embracing at base. Perianth conniving, not split quite to base, 3 lines diameter, light-green, striped and spotted with purple: sepals oblong-ovate, obtuse, with a purple stripe down the centre on outside; dorsal one largest: petals oblong-lanceolate, subacute, smaller than sepals, margined spotted and blotched with purple: labellum shorter than petals, greenish-white minutely spotted with purple without, green within, gibbous at apex, subcucullate with a minute notch on each side of lip; lateral lobes very slightly produced, conniving, with two thick transverse opposite ridges (calli) within. Capsule oblong-linear, pointletted, stout, turgid, 7–8 lines long, light-greenish, striped longitudinally with purple; densely woolly within: seeds minute, lanceolate, and with their wool light-brown.

Hab.—High up in forks of large pine trees (Podocarpus dacrydioides and P. totara), “Seventy Mile Bush” (1878–80), and at Glenross (1881, D. P. Balfour), Hawke’s Bay; flowering in September. A species allied to some of the smaller Australian species of this genus, and possessing close affinity with S. adversus, Hook. fil., but very distinct.
