This text currently parallels The Jepson Manual: Vascular Plants of California, Second Edition that is now available at the University of California Press.
Text appearing in blue on this page will not appear in the printed book; it will be displayed only on the Web. Specimen numbers are hyperlinked to records in the Consortium of California Herbaria data view where possible. Taxa are hyperlinked to entries in the Jepson Interchange via the "[Online Interchange]" link.
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, subtrop 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.
