Bothriochloa ischaemum is a perennial tufted grass, usually 30–100 cm tall, forming dense clumps through short rhizomes and basal tillers. Culms are erect or ascending, slender, cylindrical, and often branched near the upper region. Leaves are linear and flat to slightly rolled, usually 10–30 cm long, with rough margins. Leaf sheaths are smooth or hairy, and the ligule is membranous with a hairy margin. The inflorescence is a terminal digitate to subdigitate arrangement of slender racemes, usually reddish-purple to brownish. Spikelets occur in pairs, consisting of a sessile fertile spikelet and a pedicelled sterile spikelet. The fertile spikelet is awned. Fruits are small caryopses, enclosed within persistent lemma and palea.
