Eragrostis pilosa B. S. Walters

A plant of weedy habits, like others in the genus but much less common.

Eragrostis pilosa tends to have a more open, spreading panicle than E. pectinacea, with less persistent paleas.

There is considerable disagreement about whether this species is introduced from the Old World or native to North America. In any event, our first Michigan record was from Detroit (Wayne Co.) in 1924, where Farwell considered it "An annual introduced from Europe." Our few later collections are all from weedy habitats, though it is known from a more natural setting (limestone pavement) on Pelee Island, Essex Co., Ontario.
