From Flora of Indiana (1940) by Charles C. Deam
Infrequent in northern Indiana in marly or sandy soils, bordering marshes and lakes; becoming frequent to locally common on the dunes where it occurs especially on low sandy interdunal flats; rare in southern Indiana, in open post oak flats.
Stems 2-6 dm, in small clumps on long, slender, deep-seated, pale rhizomes, phyllopodic (at least the fertile stems) and often fibrillose at base, only seldom purplish below; lvs flat, 2-4.5 mm wide, surpassed by the stems; terminal spike staminate, strongly rough-pedunculate, 1.5-4 cm; pistillate spikes 1-3, mostly widely separated, erect on slender peduncles, 7-40 נ3-5 mm; bracts long-sheathing, the blade shorter than the stem; pistillate scales ovate, obtuse to acuminate or short-awned, brownish-purple-tinged with 3-nerved green center and hyaline margins; perigynia overlapping in mostly 3 rows, obovoid-fusiform, 2.5-3.5 mm, obscurely trigonous, with numerous fine nerves and 2 more prominent lateral ribs, broadest (1.5-2 mm) above the middle and evenly and broadly tapered or rounded to the beakless tip; achene broadly obovoid-trigonous, with concave sides, filling the perigynium; 2n=56. Meadows and low woods; Mass. to N.J. and Va., w. to Minn., Alta., and Nebr.
