Names
HYPSEOCHLOA cameroonensis C. E. Hubbard ex Hutch. [family POACEAE], in Hutch. & Dalz. Fl. W. Trop. Afr. ii. 530 (1936), and in Kew Bulletin, 1936, 300, fig. p. 299.
Information
A tufted annual. Culms erect or slightly geniculate, up to 1 1/2 ft. high, very slender, simple, or branched near the base, 2–3-noded, glabrous and smooth; upper internodes finally exserted. Leaves glabrous; sheaths narrow, finely striate, smooth; ligule hyaline, oblong, 1–2 1/2 lin. long; blade narrowly linear, acute, 1–3 1/2 in. long, flat, or rolled when dry, up to 1/2 lin. wide, thin, finely and closely nerved, minutely asperulous. Panicle ovate, loose, 1 1/2–3 1/2 in. long, 1/2–1 1/2 in. wide; rhachis very slender, smooth; branches paired, bare and simple towards the base, loosely trichotomously divided above, flexuous, glabrous and smooth; pedicels capillary, smooth, unequal, 1–2 1/2 lin. long, with the tips slightly thickened. Spikelets scattered, 1 1/2 lin. long, pale green or purplish. Glumes scaberulous on the keel upwards. Valves 1–1 1/4 lin. long, minutely asperulous; callus bearded with white hairs 1/4– 1/2 lin. long; awn 2–3 lin. long, geniculate at the middle, with the bristle spreading at a right angle. Valvule 7/8–1 lin. long. Lodicules nearly 1/2 lin. long. Anthers 1/10– 1/6 lin. long. Grain 2/3 lin. long.
Distribution
Nigeria Upper Guinea Cameroons Mtn., in grassland, 7500 ft., Maitland, 874! above Buea, frequent between tufts of high grasses in grassland, 9300 ft., Mildbraed, 10881! amongst rocks and boulders, 9000 ft., Maitland, 1228A! 12,000 ft., Maitland, 1274A!
Notes
The spikelets are cleistogamous, the minute anthers being enclosed in the mature florets and entangled in the hairs of the stigmas.
