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: generally erect to abruptly bent at base, generally glabrous.
Leaf: sheath margins translucent, auricles ciliate; ligule membranous or 0; blade 1.5–15 cm, 1.5–5 mm wide, flat, spreading.
Inflorescence: 1.5–11(15) cm, spike-like, cylindric or wider at base, ± open to dense; spikelets 2-ranked, 1 per node, basal generally vestigial, distal spikelets also generally reduced; breaking away as a single unit or in sections with axis segments attached.
Fertile spikelet: generally not compressed, 5–15 mm; glumes thick, hard, 3 ± veined, tips generally toothed or 1–5-awned; florets 2–5; lemma similar to glumes or firmer, toothed or 1–3-awned at tip; palea papery, 2-keeled.
Distal spikelet: 2–5 mm, similar or not to fertile spikelet, generally sterile.
21–23 species: Medit, sw&c Asia. (Greek, preferred by goats, or Latin, a sweet-fruited oak) [Saufferer 2007 FNANM 24:261–267] Interfertile with Triticum and perhaps not distinct from it. Aegilops tauschii Coss. is reported from a single occurrence in Riverside Co., doubtfully naturalized.
