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.
Stem: erect; nodes generally short-hairy.
Leaf: basal and cauline; ligule membranous; blade flat or folded.
Inflorescence: panicle-like; branches ± digitate or racemes, long-soft-hairy; axis segments grooved, breaking with age.
Spikelet: paired, dorsally compressed; sessile spikelet bisexual, glumes > florets, membranous, florets 2, lower vestigial, upper fertile, lemma translucent, tip awned; stalked spikelet staminate or sterile, pedicel hairy; spikelet pair and subtending axis segment breaking as a unit.
Fruit: oblong to fusiform.
± 35 species: worldwide, warm temperate, tropics. (Greek: pit, from pitted glumes of some species) Cult for forage, revegetation. Reports of Bothriochloa exaristata (Nash) Henrard from Los Angeles Co. are unverified. Bothriochloa ischaemum var. songarica (Fisch. & C.A. Mey.) Celarier & J.R. Harlan, infraspecific taxa not recognized.
