B. S. Walters
B. mollis of Michigan Flora.
Clearings, fields, lawns, roadsides, and disturbed places. Introduced from Europe and first collected in 1886 in Ingham Co.
Normally hairy on sheaths, blades, and culms, as well as spikelets. An occasional specimen with glabrate spikelets can be distinguished from B. racemosus by the short anthers. Almost all our plants are subsp. hordeaceus, but a single older collection from Washtenaw Co. (F. J. Hermann 6014 in 1934, MICH, WIS) is subsp. divaricatus (Bonnier & de Layens) Kerguélen (B. molliformis of Michigan Flora) with divaricate rather than straight awns; subsp. pseudothominii (P. M. Sm.) H. Scholz, with shorter glabrous lemmas has been found in southern Ontario, but not yet in Michigan.
