Bromus aleutensis, commonly known as the Aleutian brome, is a perennial grass found in North America. B. aleutensis has a diploid number of 56.

Taxonomy

It has been suggested that Bromus aleutensis may be a modified version of the similar

anther lengths close to 4.2 mm (0.17 in) in some individuals of B. aleutensis suggests outcrossing.[1]

Description

B aleutensis is a perennial grass that is loosely cespitose. The decumbent

lemmas are 12–17 mm (0.47–0.67 in) and are laterally compressed and softly pubescent. The lemmas have nine to eleven veins, with the veins being especially conspicuous distally. The awns are 5–10 mm (0.20–0.39 in) and the anthers are 2.2–4.2 mm (0.087–0.165 in).[1]

Habitat and distribution

Bromus aleutensis grows in sand, gravel, and disturbed soil in the Pacific coast, particularly from the Aleutian Islands (as its specific epithet indicates) to western Washington, though it has been found farther east in lake shores or road edges of Canada and Idaho.[1][2]

Ecology

Bromus aleutensis is infected by Fusarium nivale and Hendersonia culmicola.[3]
