Michael B. Piep

Annual, perennial herb from rhizomes or cespitose, 5–200 cm. Stem: decumbent to erect; nodes often hairy. Leaf: generally cauline; blade flat to inrolled, glabrous to short-hairy; ligule membranous. Inflorescence: spike- to raceme-like; spikelets generally 1 per node, ± cylindric, ascending to appressed, sessile to short-stalked. Spikelet: glumes unequal, <= lowest floret, 3–9-veined, acute to awned; florets 3–24, bisexual; axis breaking above glumes and between florets; lemma back rounded, 5–9-veined, acute to awned from tip; palea slightly < lemma, clearly ciliate or toothed.
± 18 species: temperate, subtropics worldwide. (Greek: short foot, from short, thick spikelet stalk in some species) [Piep 2007 FNANM 24:187–192] Reports of Brachypodium phoenicoides (L.) Roem. & Schult. from Sonoma Co. have not been verified.
