Morphology
Tufted perennial, 20-60 cm; stem surpassing the leaves; leaves 1.5-3.5 mm wide; pistillate scales lance-ovate, about equaling the body of the perigynium and therefore inconspicuous, yellowish green; perigynia greenish to yellowish or golden-brown, 3.2-4.8 mm, reflexed, contracted to the smooth beak 1.3-2.3 mm long.
Notes
Fruiting June to August
Wetland indicator: OBL
Differs from C. flava and C. viridula in that the pistillate scales are similar in color to the perigynia rather than a contrasting brownish color. Plants from the Great Lakes region of MI, IN, and OH with larger perigynia with serrulate beaks have been recently recognized as C. viridistellata Derieg, Reznicek, & Bruederle
