Order. VII. Liliaceæ

Genus 2. Callixene, Comm.

1. Callixene melantha,992 sp. nov.

Perianth darkish-green, 1¼ inches diameter; segments obtuse, 3 outer ovate-acuminate, thickish, obsoletely veined longitudinally; 3 inner narrower and thinner, broadly-linear, incurved, venation netted; filaments brown, stout, broad at base, longer than anthers; anthers bright yellow, sub-linear-ovate, 3 lines long, tips emarginate, base sagittate, extrorse; style brown, sub-angular, tapering; stigma ochraceous, small, papillose.

Hab. East sides of Ruahine mountain range, County of Waipawa; 1883: Mr. Hamilton.

Obs. I. The anthers and stigma of this species more closely resemble those of C. polyphylla (a South Chilian plant) than they do those of C. parviflora, the only known New Zealand species.

Obs. II. I have received but a single unexpanded flower! all that was by chance obtained; fortunately it was mature, uninjured, and fresh. It appears that Mr. Hamilton, on his return from the forests, was clearing out some mosses, leaves, etc., from the outer pockets of his coat, and found among them this one flower-bud (alabastrum), and kindly gave it to me. For some time it puzzled me, its dark green colour, so unlike that of a flower, and its being closely shut up, helped to disguise it; it more resembled a caper bud than anything else; but on soaking, dissection, etc., I found out what it was, and believe it will prove to be a new species of Callixene. It is allied to C. parviflora, which bears a much smaller and white flower and has a very different stigma; this latter, however, grows on the same range at a much higher altitude. [251]

Genus 5. Astelia, Banks and Solander

1. Astelia microspermum,993 sp. nov.

Leaves coriaceous, sub-linear-ovate, lanceolate, very acuminate, 2 feet 3 inches to 2 feet 6 inches long, 1½–1¾ inches wide at the broadest part above, rather suddenly and much dilated at base and there 4 inches wide and greatly overlapping and triquetrous, light yellowish-green, glabrous and shining particularly at bases but the innermost leaves have a narrow band of white hairs at their bases on the outsides, the extreme base somewhat fleshy and succulent, gummy, with a white transverse band 1 inch wide, above that it is black for 2 inches or more; under a strong lens the surface below is closely cottony appressed in minute squares, sub-incurved, deeply channelled, slightly keeled below in the centre of the leaf but not so at base, 2 prominent and stout nerves equidistant from midrib, with many finer nerves; offshoots around the base of scape sharply triangular. Female scape terminal very stout, sub-triquetrous, 9 inches long, densely clothed throughout with white silky hairs that are very long at base; panicle nodding, 6–7 inches long, composed of seven slender sub-sessile racemes 4–6 inches long and about 1 inch apart, each with a very long sessile foliaceous bract sub-ovate-acuminate, half-clasping, not cordate, 16–18 inches long, 1½–1¾ inches wide at base; flowers very small, about 1 line long, excessively numerous, compact, light yellow; pedicels sub-fascicled, 2 lines long, slender, woolly; bracteoles linear, 2 lines long, white with a brown central stripe; perianths woolly on the outside, closely embracing ovary, and nerved below to anthers; segments sub-linear-ovate, obtuse, reflexed, nerveless; ovary ovate, half or more exserted; stigma sessile, spreading, trilobed, papillose; anthers linear, very slender. Fruit small, 1½ lines diameter, sub-globular, somewhat obtusely triquetrous, with a long produced sub-angular beak, greenish; seeds very small, 14–18 in a berry, black, shining, sub-lanceolate, convex above flattish below, produced at one end. Male (whole scape not seen), sub-peduncle thickish, obtuse, cylindrical, single raceme 3 inches long, 10 lines wide; flowers light brown, densely compact, sub-fasciculate, pedicelled; pedicels 2–3 lines long, stoutish, shaggy, with an excessively narrow linear bracteole near the base, longer than pedicel and nerved; perianth large spreading, about 1 inch diameter; segments cut to base, 4 lines long, shorter than anthers, deflexed, sub-linear-ovate, obtuse; outer 3, broader, 3-nerved, tips woolly on the outside; inner 3, 1-nerved, tips thickened; filaments 3 lines long, stout, cylindrical; anthers 2 lines long, linear, obtuse, largely hastate; ovary small, sub-triquetrous, spotted white; stigma sessile, tri-orbicular, finely papillose.

Hab. Epiphytical on high trees in forests, Seventy-mile Bush, between Norsewood and Danneverke, County of Waipawa; 1884: W.C. Flowering in January. [252]

Obs. A very peculiar, fine and distinct species; of which, from its growing so very high up in the trees, it is difficult to obtain good specimens.

2. Astelia albicans,994 sp. nov.

Leaves linear-acuminate, 1 foot 3 inches to 2 feet 6 inches long, ¾ inch wide at broadest part, tips much drawn out, obtuse and hairy, drooping, stout, glabrous and green above, closely appressed with short white hairs below mixed with minute dark green dots, sub-8-nerved, edges ciliate, slightly keeled, of a blackish colour for about three inches from base; base thick, dilated, 1½ inches wide, satiny within and densely shaggy on outside with long white hairs. Male, scape flexuous, erect or slightly cernuous, 4 inches long, very stout, obtusely triquetrous, densely silky; panicle short, stout, 6–8 inches long, composed of 6 stout short obtuse sub-sessile spikes, each 2 inches long and 1 inch wide, with a broadly ovate and very acuminate bract at the base of each spike, the lowermost bract 1 foot long; perianths sessile, densely crowded, white, ¾ inch long, with a single very narrow linear-acuminate light brown bracteole at base, shorter than segments of perianth; segments cut to base, glabrous, shaggy at bases, distant, 6–7 lines long, longer than anthers, narrow-linear-acuminate, very membranous, transparent, obsoletely 3-nerved, at first erect, afterwards wholly reflexed; filaments 3 lines long, white, very stout, broad and red at base, tapering, arising from bases of segments; anthers 2–2½ lines long, linear-acuminate, hastate, light brown; stigma plumose, sessile on a beak-like projection of disk. Female scape much smaller and more slender than male, slightly drooping; panicle composed of 4 (sometimes 5) rather distant racemes, each 2–2½ inches long, ½ inch wide; bracts same as in male but narrower; perianths free, shortly pedicelled, closely enclosing ovary below; segments cut half-way to base, very small, reflexed, with here and there minute rudimentary anthers; stigma sessile, somewhat trifid, papillose; ovary ovate-acuminate, cylindrical, glabrous, greenish-yellow.

Hab. Epiphytical on trees, east slopes of Ruahine mountain range, County of Waipawa; January, 1884: Mr. A. Hamilton.

3. Astelia fragrans,995 Col.996 (Fruit).

Fruit large globular, orange-coloured with puckered sub-angled red tips (stigmatic points); calyx persistent, 6-lobed, large, free, thickened, saucer-shaped, [253] spreading, orange-coloured with dark margins; lobes very obtuse; 8 seeds in each berry; seeds black, smooth, shining, gibbous, curved, 1–1½ lines long, sharply and obsoletely and variously angled.

Obs. The coloured thick and spreading calyx of this species when the fruit is ripe has a very peculiar and novel appearance.
