Plants perennial; loosely to densely cespitose. Culms to 90 cm, erect to geniculate, not bulbous; nodes glabrous. Sheaths glabrous or densely pubescent; auricles absent; blades to 19 cm long, to 8 mm wide, glabrous or with hairs on both surfaces, hairs sometimes of mixed lengths. Spikes 3-8.5 cm, green to somewhat purple. Glumes 7-19 mm, ascending to slightly divergent at maturity. Central spikelets: glumes 9-19 mm long, about 0.2 mm wide, setaceous throughout, rarely flattened near the base; lemmas 5.5-10 mm, usually glabrous, rarely pubescent, awned, awns 3.5-14 mm; anthers 0.8-4 mm. Lateral spikelets staminate; glumes 7-19 mm, setaceous; lower glumes sometimes flattened near the base; lemmas rudimentary to well developed, awns to 7.5 mm, rarely absent; anthers 0.8-4 mm. 2n = 14, 28, 42.

Discussion
Hordeum brachyantherum is native to the Kamchatka Peninsula and western North America, and has been introduced to a few locations in the eastern United States. There is also a small disjunct population in Newfoundland and Labrador that Baum (1978) identified as H. secalinum. Hordeum brachyantherum grows in salt marshes, pastures, woodlands, subarctic woodland meadows, and subalpine meadows.
