Information
Tufted perennial; culms 30–150 cm. high, usually erect, the nodes yellowish to black and glabrous to bearded; basal leaf-sheaths usually becoming fibrous, typically woolly tomentose but sometimes silky pubescent to glabrescent. Leaf-blades linear, flat or convolute, rarely filiform, 10–30 cm. long, 2–5 mm. wide. Panicle linear to narrowly ovate, 10–30 cm. long, contracted or loose, the branches seldom markedly whorled. Spikelets narrowly lanceolate, 8–13 mm. long, light to dark brown, mostly glabrous but sometimes setose from dark tubercles; lower glume ovate-elliptic, usually 1/3 as long as the spikelet and broadly obtuse but sometimes 1/2 as long and narrowly obtuse; upper glume lanceolate, as long as the spikelet, obtuse; lower lemma similar to the upper glume; upper lemma 4–7 mm. long, pubescent, acutely bidentate (lobes 0.2–1 mm. long); awn 2.5–5 cm. long; callus narrowly oblong, 0.8–1 mm. long, 2-toothed; stamens 2.

Notes
Two segregates are commonly recognized, L. camerunensis from Cameroun and L. stipoides from Madagascar. Variation in East Africa readily engulfs both species, which seem to be no more than extreme forms. None of the other segregates appear to be of any biological significance, and I have therefore treated L. simplex as a single variable species.
