DescriptionThis perennial sedge consists of a dense tuft of leafy culms about 1½-2½' tall. Dried remnants of older leaf blades are usually persistent around the base of the tuft of culms. Over time, the tuft of culms becomes elevated, forming a tussock. The narrow culms are about 1 mm. across, 3-angled, light green, and glabrous. Underneath an inflorescence, the margins of a culm are often slightly rough. Each culm has 3-5 alternate leaves along the lower one-third of its length. The ascending to spreading leaf blades are 1-3 mm. across. and 3-9" long; they are light to medium green and glabrous with rough-textured margins. The leaf sheaths are light green and glabrous along their outer 2 sides, while their inner sides are membranous and hairless. The summit of each sheath along the inner side is concave. Each fertile culm produces a narrow inflorescence about ¾-2½" long consisting of 3-8 erect to ascending spikelets; the inflorescence may nod slightly. Each spikelet is usually gynecandrous with 0-3 staminate (male) florets at the bottom and 6-18 pistillate (female) florets above. Individual spikelets are up to 15 mm. (2/3") long; except for the lowest spikelet, they usually overlap each other along the rachis (central stalk) of the inflorescence. Underneath the lowest spikelet, there is usually a narrowly linear bract about ¼-1" in length, otherwise the bracts of the inflorescence are insignificant and scale-like or absent. The perigynia of the pistillate florets are 3.5-5.0 mm. in length and 1-1.25 mm. across; they are narrowly lanceoloid in shape and plano-convex, tapering gradually to a narrow beak. Their lateral margins are rounded, rather than narrowly winged, while their bases are somewhat spongy and thickened. There are several longitudinal veins on both the inner and outer sides of each perigynium. The exterior surface of each perigynium is light green and glabrous, although it becomes whitened toward the base. The pistillate scales are 2.5-4.0 mm. long and lanceolate in shape with membranous margins. Each female floret consists of an ovary with a pair of stigmata at its apex. The blooming period occurs from mid- to late spring. The florets are cross-pollinated by the wind. During the summer, the spikelets change from light green to light tan. The achenes and their perigynia can float on water or be blown about by the wind. Individual achenes are about 2.0 mm. long and 0.75-1.0 mm. across. The root system is short-rhizomatous and fibrous.
