Leaves: Sheaths open; blades tough, rough to sometimes finely hairy, mostly flat, (5) 8-20 mm wide; ear-shaped lobes usually well-developed at some leaf-bases; ligules usually short-hairy, membranous, (2) 3-7 mm long.
Flowers: Inflorescence a stiff, erect spike, (9) 12-20 (25) cm long, sometimes compound, the lateral branches with as many as 5 or 6 spikelet-bearing nodes; spikelets sometimes paired, but usually 3 or more per node, (3-) 4- to 6-flowered, often 1 or more stalked; glumes narrow, awl-like, tapered from the base, 10-20 mm long, often as long as the spikelets; lemmas smooth to inconspicuously hairy, about 10-15 mm long, unawned or more usually awn-tipped, the awns 2-7 mm long; anthers 3-6 mm long.
