Leaves: basal sheaths purple, 7-18 mm; blades erect or ascending, evergreen, midrib and 2 lateral veins strongly developed, 14-42 cm × 8-32 mm, older leaves often shriveling or dead at tips. Inflorescences: spikes 3-5 per culm, scattered; peduncle of pistillate spikes erect or spreading, rarely drooping, exserted 0-18 mm; bracts from middle and proximal portions of culms reduced, 0.8-2 cm × 2-3.5 mm. Pistillate spikes the proximal basal, 8-30 × 4-7 mm. Staminate spike 1, pedunculate, oblanceolate to linear, 8-20 × 2-3.5 mm. Pistillate scales slightly keeled, 3.2-4.2 × 1.8-2.2 mm, midribs green, margins hyaline with purple outward, apex cuspidate to acuminate to acute. Staminate scales 3-6 × 1.5-2 mm, midveins green or purple, margins dark purple, apex obtuse. Anthers 3.2-4.2 mm. Perigynia (4-)9-13(-15) per spike, overlapping, finely veined, elliptic, 3.7-4.9 × 1.6-2 mm; beak constricted. Achenes ovoid, 2.2-2.7 × 1.5-1.9 mm, sides flat to slightly concave at maturity, tightly fitting in perigynia. Style ascending from achene through entire orifice. 2n = 50, 52. Fruiting spring.

Rather infrequent in the northern counties in rich woods. South of the lake area it is local and found mostly in humus on the wooded sandstone slopes of deep ravines, usually in dense shade and associated with Hydrophyllum appendiculatum. No specimen was found to confirm the report in Coulter's Catalogue from Tippecanoe County.
