Plants hermaphroditic, caespitose or rhizomatous, annual or perennial. Culms ascending or geniculate, glabrous or pubescent;
internodes hollow, terete. Leaves basal and cauline, not distinctly distichous; sheaths terete, margins open; auricles absent;
ligules membranous; blades flat, linear (short), lax. Spikes or raremes, bilateral, rachis persistent. Spikelets
solitary, ascending, laterally compressed, disarticulating above the glumes, awned, sessile or pedicellate;
florets 9-20, reduced floret at apex; rachilla not extending beyond upper floret; glumes 2, opposite, unequal,
shorter than first floret, awned or awnless; lemmas 7-veined, chartaceous, glabrous, apex entire

A genus of about 16 species that occur in temperate climates and tropical mountains. Many of these taxa
are adapted to disturbed habitats. Our species (B. distachyon) is a weedy species.
