9. C. quadribracteolata, Col. in Trans. N.Z. Inst. xiv. (1882) 329.—Stems and branches very slender, branched, trailing, 1–3 ft. long, glabrous except the very young shoots. Leaves few, trifoliolate; petioles slender, 1–2 in. long; leaflets minute, 16–14 in. long, usually Imear or lanceolate, but varying to linear-oblong, ovate-lanceolate, or triangular-acute, glabrous, entire or one or all 3-lobed. Peduncles solitary or 2–3 together in the axils of the leaves, 1-flowered, usually shorter than the petioles, pubescent; bracteoles 2 or 3 pairs, connate, upper the largest, sheathing at the base, rounded, obtuse. Flowers purplish, sweet-scented, ¼–¾ in. diam. Sepals 4, linear or linear-oblong, usually acute, silky. Anthers linear. Achenes small, almost glabrous when fully ripe, narrowed into short plumose tails.—Kirk, Students' Fl. 4. C. fœtida var. depauperata, Hook. f. Fl. Nov. Zel. i 7; Handb. N.Z. Fl. 2.
North Island: Low grounds in the Hawke's Bay District; Lake Rotoatara, Colenso! Petane, A. Hamilton! between the Ngaruroro and Tukituki Rivers, Sturm.
This can only be separated from the preceding by its smaller size, more slender habit, narrower leaflets, purplish flowers, and narrower sepals. Further investigation may prove both to be forms of one variable plant.
2. MYOSURUS, Linn.
Annual herbs, of small size. Leaves all radical, linear, entire. Scapes usually numerous, naked, 1-fiowered. Sepals 5, rarely more, minutely spurred at the base. Petals wanting in the New Zealand species. Stamens 5–8. Carpels numerous; ovules solitary, pendulous. Achenes closely packed on a long and slender spike-like receptacle which usually lengthens much as they ripen, each with a raised nerve on the back, ending in a short persistent style.
A small genus of only two species, one of which is widely spread in the north temperate zone, and is also found in Australia; the other is known only from California, Chili, and New Zealand.
1. M. aristatus, Benth. in Lond. Journ. Bot. vi. 459.—Varying, in size from 1–3 in. Leaves numerous, 120 in. broad or even less, erect, linear or linear-spathulate. Scapes usually several, slender, 1-flowered. Flower minute, yellowish, apetalous. Sepals 5, spur short. Stamens generally 5. Receptacle in fruit oblong or linear, ¼–¾ in. long; achenes with a short beak.—Hook. f. Fl. Nov. Zel. i. 8; Handb. N.Z. Fl. 3; Kirk, Students' Fl. 5.
