Culms to 70 cm. Sheaths smooth or retrorsely scabridulous, usually glabrous, sometimes pubescent; ligules 0.7-2.6 mm, glabrous, erose; blades 8-18 cm long, 2-10 mm wide, flat. Panicles 15-20 cm long, 1.5-2.5 cm wide, nodding, not spikelike, spikelets loosely arranged. Spikelets 4-5.2 mm. Lower glumes about 1/3 as wide as the upper glumes; upper glumes 3-3.9 mm, elliptical to oblanceolate, not subcucullate, width/length ratio 0.17-0.26, apices acute; lowest lemmas 3.1-4.2 mm, glabrous; distal lemmas usually smooth on the sides, rarely scabridulous distally, unawned; anthers 0.2-0.7 mm. 2n = 14.

Discussion
Sphenopholis longiflora grows in forest bottoms along bayous and streams, from 0-50 m, in Texas, Arkansas, and Louisiana. Erdman (1965) treated both S. longiflora and S. intermedia as S. obtusata var. major (Torr.) Erdman. They are morphologically distinct from each other, and from S. obtusata.
