This densely tufted grass is a relatively recent introduction from Europe, first collected by A. A. Reznicek in Berrien Co. in 1982 (Gereau & Rabeler, 1984). It is now very locally frequent in the "sand country" of southwesterm Michigan and is probably increasing.
It somewhat resembles Koeleria, but has the filiform-involute leaf blades finely and densely scabrous, and differs in its unique, jointed awn. Koeleria has the blades smooth or sometimes sparsely pilose and the lemma awnless.
