Discussion
Sphenopholis nitida grows in moist to dry, deciduous and coniferous forests, on clay or silt banks and slopes, at 0-1200 m, in southern Ontario and the eastern United States. It can be confused with occasional forms of S. obtusata that have somewhat scabrous distal lemmas, but S. nitida has broader lower glumes.
