Morphology

Loosely tufted perennial; stems slender, erect, 20-60 cm, typically much surpassing the leaves; leaves 1-1.5 mm wide; inflorescence 1-2 cm with a small terminal staminate spike and 2-3 closely crowded pistillate ones; pistillate scales reddish-brown with a broad hyaline margin and pale center, wider but shorter than the perigynia, blunt or rounded, sometimes shortly mucronate; perigynia 3-12, dull- to yellowish-green, short-hairy, 2.7-4.1 mm, slightly flattened, narrowly obovoid above a stipe-like base, 2-keeled, abruptly contracted to a slender beak 0.5 mm; achene rounded-trigonous.

Notes

Fruiting mid May to early July

Wetland indicator: NA

Differs from C. albicans and similar species in that the pistillate scales are noticeable shorter than the perigynia. Can be distinguished from C. deflexa by the larger perigynia (3.2-4.2 mm long vs. 2.3-3.1 mm long), and the longer and more robust culms that exceed the leaves (vs. culms equaling or shorter than the leaves).
