Names
CYPERUS pilosus Vahl [family CYPERACEAE], Enum. ii. 354. —Kunth, Enum. ii. 80; Boeck. in Linnæa, xxxv. 598, and in Flora, 1879, 551; C. B. Clarke in Hook. f. Fl. Brit. Ind. vi. 609, and in Durand & Schinz, Conspect. Fl. Afr. v. 571.
CYPERUS marginellus Nees [family CYPERACEAE], in Wight, Contrib. 83; Kunth, Enum. ii. 75.
Information
Glabrous, except the rhachis of the spikes. Stolons slender, finally hardening into rhizomes. Stem 1–2 1/2 ft. long, at the top acutely triquetrous. Leaves 3/4 the length of the stem, 1/6– 1/3 in. broad. Umbel usually compound; rhachis of the spikes minutely hairy; bracts several, similar to the leaves, the lowest overtopping the umbel. Spikelets spicate, divaricate at right angles, 1/2– 2/3 by 1/12 in., pale reddish, compressed, 10–24-flowered; rhachilla scarcely winged. Glumes ovate, obtuse, rather loosely imbricated. Nut 3/5 the length of the glume, ellipsoid, acutely trigonous, black.
Range
Abundant in India; extending to Japan, Malaya and Queensland.
Distribution
British East Africa Nile Land Jur; Jur Ghattas, Schweinfurth, 2017!
Notes
Schweinfurth's plant has the rhachis of the spikes only minutely hairy, and thus agrees with the form “ marginella ” (sp.) Nees. The examples are young and perhaps should be sorted rather with C. procerus, Rottb. var. lasiorrhachis (Hook. f. Fl. Brit. Ind. vi. 610); Boeckeler considers that no specific line can be drawn between this and C. pilosus .
