Hordeum (an ancient Latin name for barley). Gramineae. Annual or perennial grasses with terminal bristly spikes. Spikelets 1-fld., 3 together at each joint of the rachis, the middle one sessile and perfect, the lateral usually pedicelled, often reduced to awns: the rachis breaking up at maturity into single joints with the cluster of spikelets attached.—Species about 16, temperate regions of both hemispheres. Elymus, some species of which resemble Hordeum, differs in having 2 developed, several-fld. spikelets at each node. Hordeum includes the cult, barley (H. vulgare, Linn.) and several troublesome weeds. Among the latter may be mentioned, H. murinum, Linn., called Wild Barley, Barley-grass and Foxtail on the Pacific slope; H. nodosum, Linn., common throughout the U.. S., and H. jubalum, Linn. Squirrel-tail Grass, called Fox Tail in Wyo. and Tickle-grass in Nev. The first two are annual. The last, a perennial, is also cult, for ornament.
