Description Leaves in tufts of 3-6, distinct from the flowering culms, 8-12 in. long, 14-13 lin.| broad, linear, aeute, often folded, but when expanded channelled down the face, with an acute ridge on each side of the channel, flat on the back, thinly pilose, usually slightly recurving. Flowering culms 14-18 in. high, including the panicle, 1-$ lin. broad, flattened, slightly concave on one side, convex on the other, sparingly pilose or nearly glabrous, produced on distinct leafless shoots, embraced by a long glabrous leafless sheath at the base. Panicle 7-12 in. long, strictly erect, linear, composed of 4-5 distant tufts of erect, simple or once umbellately divided, filiform branchlets, clustered in the axils of
close-fitting brown sheaths 3—2 in. long, which have spreading leafy points 4-1 in. long. Spikelets solitary or very rarely 2 at the end of the branchlets, light brown. Male spikelets 3-4 lin. long, 1-14 lin. thick, lanceolate, with 5-7 coriaceous, oblong, acute, mucronate, brown empty glumes, thinly and minutely pubescent on the back, and 4—6 membranous, oblong, obtuse, fertile glumes; stamens 6-12 under each glume; anthers 2 lin: long, linear, tipped with a minute tuft of stiff hairs. Female spikelets all at the apex of the panicle, more slender than the males, 3 lin. long, about 3 lin. thick, with about 5 oblong-lanceolate, acute, mucronate, minutely ciliate glumes surrounding the solitary pubescent ovary; stigmas 3, densely villose ; hypogynous hairs copious.
