Bromus latiglumis

Bromus latiglumis, the earlyleaf brome, is a grass native to North America. The specific epithet latiglumis is Latin for "broad-glumed", referring to the wide glumes.

Description
Bromus latiglumis is a perennial grass that grows in mats or clumps 0.5-2 m tall. The leaves are cauline. Sheaths are ribbed and glabrous, covering most nodes. The dark green leaf blades are 5-17 mm wide with a white midrib. The ovoid panicle is 15-30 cm long. The branches of the panicle are either spreading or reflexed and have large basal pulvini. The branches solitary or occur in pairs. The elliptical or oblong spikelets are 1.5-3.5 cm long and 5-9 mm broad. The spikelets are loosely flowered with three to eight flowers on each spikelet. The glumes are either pilose or glabrous. The five to seven nerved lemmas are 3-4 mm long and are mostly glabrous though sericeous towards their base. The awns are 2-6 mm long. The palea has a rounded tip and the anthers are 1.5-2.5 mm long.

The grass flowers from August to September. The grass occurs in wet woods and prairies, stream banks, and alluvial plains.
