|discussion=<p>Sphenopholis obtusata grows in prairies, marshes, dunes, forests, and waste places, at 0-2500 m. Its range extends from British Columbia to New Brunswick, through most of the United States, to southern Mexico and the Caribbean. The distal lemmas of S. obtusata are occasionally somewhat scabrous. Such plants can be distinguished from S. nitida (p. 621) by their narrower lower glumes, from S. filiformis (p. 621) by their wider leaves, and from S. pensylvanica (p. 621) by their shorter, unawned spikelets. Hybrids with S. pensylvanica, called Sphenopholis xpallens, have short (0.1-4 mm) awns on the distal lemmas.</p>
