Tufted or stoloniferous perennial, the basal sheaths silky pubescent; culms 20–150 cm. high, ascending. Leaf-blades broadly linear to narrowly lanceolate, 2–30 cm. long, 3–20 mm. wide. Inflorescence of (2–)3–15 racemes on a common axis 3–12 cm. long; racemes 2–8 cm. long, bearing single or sometimes paired spikelets on a narrowly winged rhachis. Spikelets ovate, 3–5 mm. long, acuminate; lower glume oblong (1/2–)2/3–3/4 the length of the spikelet, membranous, 3-nerved, often with a tuft of hairs from the middle of the back, obtuse; upper glume glabrous or pubescent; lower lemma with or without a setose fringe; upper lemma rugulose, with a mucro 0.5–1.2 mm. long.

Notes
U. mosambicensis and U. oligotricha are very closely allied, but can usually be distinguished by differences in the nervation, shape and texture of the lower glume. Needless to say intermediates occur, and the boundary between the species (and their annual counterparts) sometimes becomes blurred.
