(New Mexico Sedge)

Carex occidentalis is an upper elevation montane sedge which grows in clumps with the slender culms held above the flat, thin leaves. The spikes are androgynous (staminate flowers above the pistillate ones in the spike) and the spikes are rather loose. The pistillate scales are about the same length as the perigynia with a greenish central stripe.
