An inconspicuous little Eurasian weed, first collected in Michigan at East Lansing (Ingham Co.) in 1920 but not again until 1979, when it was collected by K. Dritz in cracks of old pavement near a railroad in Berrien Co. Now known from a number of scattered sites, in sandy roadsides, lawns, parking lots, and even sometimes sandy or rocky riverbanks and lakeshores, expecially in urban areas.
Plants are prostrate and a distinctive yellowish-green color, though small and easily overlooked; it may be more widespread than collections suggest.
