Basic Description: A slender perennial sedge.
Technical Description: Tufted, red-purple at base; main leaves erect, equaling the stems, 2-4 mm wide; blades glabrous; sheaths glabrous to hairy; spikes 2-5, usually 3, the terminal one pistillate above, staminate below; pistillate spikes approximate, short-cylindric or narrowly ovoid, 8-15 mm, sessile or nearly so; lowest bract elongate, much surpassing the spikes, the others small; anthers 1.3-2 mm; pistillate scales usually much shorter than the perigynia, the body with brownish hyaline margins, acute to short-cuspidate; perigynia flattened-obovoid, 2-2.8 x 1.3-2 mm, appressed-ascending, 2-ribbed, rounded at the beakless tip, usually nerveless ventrally. (Gleason and Cronquist 1991; not including their var. hirsuta (= C. hirsutella))
Diagnostic Characteristics: Within Section Virescentes, distinguished by (1) terminal spike pistillate above, staminate below; (2) perigynia glabrous; (3) perigynia appressed-ascending, much wider than thick, obscurely nerved; (4) scales of pistillate flowers 2-3 mm long, obtuse to short-pointed, shorter than the perigynium; (5) distinguished from C. hirsutella (formerly C. complanata var. hirsuta) by the following characters: leaf blades glabrous or sparsely and minutely pilose, hard, subrigid, prominently keeled; sheaths glabrous to hairy; the perigynia usually nerveless ventrally (C. hirsutella has the leaf blades soft-hairy, soft, flat, not conspicuously keeled; leaf sheaths soft-hairy; and the perigynia with distinct nerves on both sides). (Gleason and Cronquist 1991, Fernald 1950, Steyermark 1963)
Duration: PERENNIAL
Reproduction Comments: Lower spikes pistillate, upper ones with pistillate flowers above staminate flowers. Cyperaceae are wind-pollinated with the exception of Dichromena.
Terrestrial Habitat(s): Forest/Woodland, Grassland/herbaceous, Old field, Woodland - Conifer, Woodland - Hardwood
Habitat Comments: In dry to moist, often sandy, places: upland or low woods, pinelands, clearings, fields, old fields, meadows, ditches; at least in southern part of its range, sometimes in bottomlands subject to infrequent flooding. (Fernald 1950, Gleason & Cronquist 1991, Godfrey & Wooten 1979, Hough 1983, Radford et al. 1968, Steyermark 1963)
