Deciduous forest understories and edges; forming dense mats. First collected in Michigan in 2011 in Lenawee Co.

This is a dangerous pest, very recently discovered in Michigan, and hopefully, it will be possible to contain its spread. To the south, it has densely invaded forest understories, and seriously altered them. The decumbent bases of this annual, with its stilt-like roots will allow easy identification, especially contrasted with the perennial rhizomes of the somewhat similar forest understory species Leersia virginica. Spikelets can be either awned or awnless; both variants have been collected in Michigan.
