Bromus kalmii

Description

Bromus kalmii is a perennial grass, with solitary or slightly tufted culms that grow 0.4-1.2 m tall. The culms are pubescent just below the nodes. The grass typically has three to five and occasionally six leaf blades. The firm and scabrous leaf blades are either pubescent or glabrous and are 7-17 cm long and 4-10 mm wide. The glabrous or sometimes shaggy sheaths are mostly shorter than the internodes and each have a V-shaped cleft. The ligule is typically 0.5 mm long. The narrow, crowded panicle is 5-15 cm long. The lower branches of the panicle are very slender and each bear one or two spikelets. The five to eleven flowered spikelets are 1.4-2.6 cm long and 5-6 mm wide. Both glumes have short, adpressed hairs. The lower glume is three-nerved and the upper glume is five-nerved. The densely hairy lemmas are oblong to elliptical in shape, and have straight awns 1-3 mm long. The oblong and flat palea is slightly shorter than the glume. The anthers are approximately 2 mm long.

The grass flowers from July to through August.

Habitat

Bromus kalmii grows in dry or moist open areas or thickets, especially on calcareous soils.
