General Description
Palish Sedge is a clumped perennial with flowering stems 15-75 cm high. Leaves are pale green, flat, 2-5 mm wide, and the lower have long, spreading hairs. 3-5 spikes are borne on the top of the stem. The terminal spike is made up of male flowers, and the lateral spikes are thick-cylindrical, 0.5-2.2 cm, on short stalks and made up of female flowers. Scales are acute and about the same length as perigynia. Perigynia are rounded on top, without a beak, and nerveless or faintly nerved. Each periygnium has 3 styles and a lens-shaped achene.

Phenology
Fruiting in late June - early July.

Diagnostic Characteristics
Distinguished from Carex torreyi by the rounded perigynium top, lack of a beak and lack of a strongly-ribbed surface. A hand lens or microscope are needed for positive identification.
