Plants usually oblong in the upper portion, sometimes cylindrical. Culms 1-2 m; internodes not glaucous. Sheaths scabrous; ligules ciliate or not, cilia to 0.3 mm; blades green, usually pubescent. Subtending sheaths of inflorescence units (2) 2.4-3.1 (4) mm wide; peduncles 2-5 (8) mm; rames usually 1.7-2.8 cm, not exserted at maturity. Keels of lower glumes usually smooth below midlength, scabrous distally; anthers often retained within the spikelets.

Distribution

Va., Okla., Miss., Tex., La., Ark., N.J., Ala., Tenn., Ga., Ky., Fla., Md., N.C., S.C.
