Roadsides, fields, banks, and disturbed ground. Native of Europe; first collected as early as 1840 in Macomb Co.
A distinctive plant when ripe, with strongly inrolled lemmas and tendency for the tip of the grain and palea to be slightly exserted. Occasional plants have the lowermost sheaths with short hairs, but can usually be identified by the long palea and (if ripe) strongly inrolled lemmas, combined with the relatively short and strongly undulate awns.
