820 20 bis. C. Darwinii, Boott. in Proc. Linn. Soc. i. (1845) 261.—Rhizome thick, creeping, stoloniferous. Culms 1–3 ft. high, stout below, slender and drooping above, sharply triquetrous, faces concave. Leaves numerous, equalling or longer than the culms, ⅕–⅖ in. broad, margins and midrib sharply scabrid; bracts leafy, the lower far exceeding the culms. Spikelets numerous, 6–15, dark ferruginous-brown, distant, long-stalked, pendulous, ½–3 in. long; upper 1–3 male, solitary or the lower geminate; the remainder female but often with a few male flowers at the top, geminate or ternate, lax-flowered at the base. Glumes lanceolate or ovate-lanceolate, dark-brown with a pale keel, 1–3-nerved, cuspidate. Utricle ovate, plano-convex, 3–5-nerved on each face, minutely papillose-granulate and more or less spotted with purple, narrowed into a very short beak with an almost entire mouth. Styles 2. Nut broadly obovoid.—Hook. f. Fl. Antarct. ii. 364, t. 145.
Chatham Islands: Lowland swamps near Lake Huro, Cockayne.
Also in South America, where it stretches from Chili to the Straits of Magellan and Fuegia. I have not seen New Zealand examples, and the above description has been drawn up from those given by Boott and Kukenthal. The latter author, who has examined Dr. Cockayne's specimens, states that they are referable to the variety urolepis (C. urolepis, Franohet), which differs from the type in the glumes being produced into awns much longer than the utricle. C. Darwinii comes nearer to C. ternaria than to any other New Zealand species, principally differing in the utricle and glumes.
