Herbs perennial, cespitose, to 1 m; rhizomes scaly; offshoots cormose. Culms erect to leaning, smooth except in inflorescence. Leaves: all sheaths hispid-hirsute, sometimes also hirtellous; principal blades linear, 8–20 cm, abaxially puberulent, hispid-hirsute, adaxially hispid-hirsute-ciliate, scabridulous. Inflorescences in clusters of terminal spikelets or from 1–3 penultimate nodes, proximalmost involucral bract longest, exceeding inflorescence, distal 1–2 bracts shorter. Spikelets ovoid to cylindric-lanceoloid, 1–2 cm, apex acute; fertile scales 2.5–3.5 mm; cusp excurved, more than 1/2 length of scale, scabrid; ribs 3–5(–7). Flowers: perianth bristles reaching base of perianth blades or beyond, retrorsely barbellate; perianth blades narrowly to broadly ovate, uniformly compressed or distally tumid, 1 mm, base 3-ribbed, apex incurved, acuminate; anthers 3, 1 mm. Achenes: stipe shorter than perianth stipe; body angles wirelike, pale, faces deep brown to chestnut brown, faintly cross-lined, 1 mm. 2n = 46. Rhizomatous perennial to 10 dm, the stems arising from axillary, cormose offshoots; sheaths all hispid-hirsute; larger blades 8–20 cm × 4–10 mm; hispid-ciliate and scabrous or hairy on the surfaces; spikelets to 20 mm, in 1–3 clusters; scales 2.5–3.5 mm, with 3(5) strong median nerves convergent and exserted to form a spreading-recurved awn more than half as long as the scale; bristles antrorsely barbellate, reaching to the base or even the tip of the pet-blades, these ovate, usually incurved-acuminate; anthers 3, ca 1 mm; 2n=46. Moist or wet, often sandy places; L.I. to n. Fla., w. to Tenn., Ark., and Tex., mainly on the coastal plain with us.
