Ecology & Life History

Basic Description: A sedge, growing in tufts, the leaves up to 1 cm wide, the flowering spikes of two types: a very narrow delicate male spike rising above one or two large roughly globular female spikes.
Technical Description: Plant pale or gray-green; stems 3-9 dm, solitary or in small clusters, scabrous on the angles above; rhizomes wanting; basal sheaths persistent, purplish-red; leaves 4-11 mm wide, the uppermost nonbracteal one (as also the bracts) sheathless or with a sheath seldom over 1 cm; terminal spike staminate, 0.5-5.5 cm, on a peduncle of 0.5-6 cm, the scales scarious, acute to aristate; pistillate spikes 1 or 2, densely flowered, globular, more or less approximate, on peduncles 0.7-3.5 cm, their bracts leafy, 8-26 cm; pistillate scales 4-11 mm, lance-ovate to orbicular-ovate, often tipped with a rough awn to 7 mm; perigynia 8-35, radiating in all directions from the short axis, dull, sometimes hispidulous, 12.5-20 x 4-8 mm, strongly 16-25-nerved, rhombic-ovoid, cuneate to the base, tapering from the widest point to a poorly defined, bidentate beak 1.5-3 mm, the teeth hispidulous internally; scales ovate, much shorter than perigynia, scarious with green midrib; achene 3.3-4.8 x 2.6-3.7 mm, convexly trigonous, not thickened on the angles; style persistent but withering, sometimes contorted; 2n = 52, 54. (Gleason & Cronquist 1991, with some details from Fernald 1950 and Radford et al 1968)
Diagnostic Characteristics: Within Section Lupulinae, distinguished as follows: (1) sheath of the uppermost nonbracteal leaf wanting or less than 1.5 cm; (2) stems solitary to densely cespitose, without elongate stolons; (3) perigynia less than 1 cm long, the beak 1.5-4.2 mm; (3) pistillate spikes globose; (4) distinguished from C. intumescens by the following characters: perigynia dull, cuneate to the base, mostly 8-35 per spike, radiating in all directions (C. intumescens has the perigynia lustrous, convexly rounded to the base, mostly 1-12 per spike, ascending or spreading). (Gleason & Cronquist 1991, Fernald 1950)
Duration: PERENNIAL
Reproduction Comments: Staminate spikes borne above the pistillate spikes on the same stem. Cyperaceae are wind-pollinated with the exception of Dichromena. The inflated perigynium allows Carex seeds to float for long periods of time (2 days to over 12 months, depending on the species), and various species are also dispersed by ants, birds, and mammals (Ridley 1930).
Palustrine Habitat(s): FORESTED WETLAND, HERBACEOUS WETLAND, Riparian
Terrestrial Habitat(s): Forest - Hardwood, Forest/Woodland, Grassland/herbaceous, Woodland - Hardwood
Habitat Comments: Moist to wet woods, wet places in woods, swamps, floodplains, banks of creeks, wet meadows, marshes. (Deam 1940, Fernald 1950, Gleason & Cronquist 1991, Godfrey & Wooten 1979, Hough 1983, Radford et al. 1968, Steyermark 1963, Strausbaugh & Core 1978, Voss 1985).
