A small annual grass introduced from Europe and first collected in 1992 by Ken Dritz in Berrien Co. (Cusick et al. 2002). Spikelets are usually ± sessile and single at the nodes, but robust plants may have slightly branched inflorescences. Sclerochloa somewhat resembles Poa annua, with which it often occurs, but can be easily distinguished by its sessile or nearly sessile spikelets and truncate to rounded, strongly 3–7-nerved glumes. Poa annua has pediceled spikelets with acute, faintly 3-nerved glumes.
