Cosmopolitan. 2 subspecies. Narrow-leaved Carex echinata is identified by its widely spreading, gradually tapering perigynia in star-like spikes. |
High montane to alpine streamsides, seeps, moist to mesic meadows, and open forests, sometimes in wind-swept sites that have little snow accumulation, but not in fully dry sites. 1300–2800 m. BR, BW, Casc. CA, ID, NV, WA; north to British Columbia, east to CO. Native. Carex heteroneura is a coarse, cespitose, sedge with erect spikes (except sometimes the lowest) and broad, flat perigynia. Its entire inflorescence tends to nod when fully ripe. The more common C. spectabilis is similar, but its spikes lack the contrast between dark female scales and light perigynium margins, its spikes are less crowded, and it is a finer textured plant. Rare C. atrosquama has elliptical, golden perigynia. Two subspecies have been recognized in C. heteroneura, but variation is continuous. |
