Sphenopholis obtusata (Michx.) Scribn.[FNA24, HC, HC2]
prairie wedgescale

Publication: Rhodora 8(92): 144. 1906.

Origin: Native

selected vouchers: WTU

Notes: FNA24: "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 by their narrower lower glumes, from S. filiformis by their wider leaves, and from S. pensylvanica by their shorter, unawned spikelets. Hybrids with S. pensylvanica, called Sphenopholis ×pallens, have short (0.1–4 mm) awns on the distal lemmas."
