English: Cleft sedge, is very abundant in moist meadows of the Sierra Nevada and especially along the JMT. It is perhaps the most common sedge in this area, at least in moist meadow sites. The perigynia beaks are sometimes sparsely setose. This species seems nearly indistinguishable from Carex luzulina, woodrush sedge, that later of which has a narrower less-purple-pigmented sheath of the inflorescence bract.
