General Description: Perennial tufted sedge with a short rhizome and obtuse-angled culms that are terete at the base. The leaves are gray-green and 1-2 mm in width, with brown-spotted sheaths. Heads are 3-4 cm long with 10 or more sessile spikes per head. The staminate flowers occur at the tip of the spike with the pistillate flowers at the base. The scales are light brown and acute; the perigynia are dark brown and broadly ovate and long-beaked.
Diagnostic Characteristics: From CNHP Wetland Guide 2012: Main Characteristics:
Front of leaf sheath with red or brown dots, especially near mouth
Perigynia: ovate or lance-ovate, tapering at apex, firm and thick-walled, glossy, short-stipitate, dark brown, 2-3 mm long, dorsal suture on ventral side
Pistillate scales ovate to oblong-ovate with an acute to cuspidate tip, brownish with pale midrib and wide hyaline margins
Beaks coarse, tapering, serrulate-margined
