Flower panicle are contracted, often dense, 10-30; branches 3 to several per node, nearly erect or narrowly rising up, with spikelets to base. Spikelets are 7-10 mm, yellowish green or purple; glumes subequal, elliptic-oblong, 3-veined, smooth or scaberulous, often rough-spinulose on midvein, tip pointed or finely toothed; callus pointed, 0.5-1 mm; lemma narrowly lanceshaped, leathery, 5-8 mm, densely hairy.
