Perennials; culm tufted, 40-90 cm tall, nodes pilose. Blade linear, pilose, 10-30 cm long, 5-8 mm
wide; sheath long, pilose; ligule membranaceous, truncate, 1-2 mm long. Inflorescence of racemose
racemes, 5-20 cm long; racecmes 3-5, ridged on main axis, 5-10 cm long, axils of racemes with tuft of
hairs; rachis ca. 0.8 mm wide; pedicel short. Spikelets 2.5-2.7 mm long, broadly elliptic or elliptic, rounded or slightly mucronate, sparsely covered with spreading hairs on margins; upper glume
and lower lemma similar, 3-veined, membranaceous; upper lemma coriaceous, as long as spikelet,
slightly shiny.
