Agropyron repens of Michigan Flora.
A familiar weed of roadsides, clearings, fields, gardens, and disturbed ground generally; spreading into forests and on shores and dunes, where often appearing as if native. Introduced from Eurasia, at least in Michigan. While first collected in 1845 in Macomb Co., most collections are post-1900.
Extremely variable in the nature of awns, glumes, and pubescence of rachis. Rarely a robust plant will have 2 spikelets at most nodes of the spike and, with wide leaves, will thus closely resemble E. glaucus; however, the anthers of E. glaucus are shorter than the distinctive long ones of E. repens (3–6 mm), and E. glaucus lacks long-creeping rhizomes.
