Oregon sedge is a rare (CNPS 2B.3) California native perennial found in the Klamath Ranges and High Cascade Range in dry upland and forest edge habitats at elevations of 1,300 to 2,200 meters. The sedge produces erect spikelets with pistillate flower bracts that are often purple-tinged with white margins. Growing with rhizomatous stems 10 to 50 centimeters tall, it has distinctive ascending leaf blades that are strongly V-folded and 3 to 5 millimeters wide. Its leaves are glabrous and ascending, creating a tidy, structured appearance in forest understory environments. The fruit features thick-walled perigynia that are green to gold, with strongly ribbed surfaces and small erect teeth at the beak.
