|discussion=<p><i>Sphenopholis obtusata</i> 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 <i>S. obtusata</i> are occasionally somewhat scabrous. Such plants can be distinguished from <i>S. nitida</i> (p. 621) by their narrower lower glumes, from <i>S. filiformis</i> (p. 621) by their wider leaves, and from <i>S. pensylvanica</i> (p. 621) by their shorter, unawned spikelets. Hybrids with <i>S. pensylvanica</i>, called <i>Sphenopholis</i> xpallens, have short (0.1-4 mm) awns on the distal lemmas.</p>
