Springs and fens on serpentine substrates, often with Darlingtonia californica, usually in a dense thatch of old leaves. 300–1100 m. Sisk. CA. Native. Carex klamathensis is a rare, glaucous, rhizomatous sedge of serpentine fens, with pale, veined, somewhat papillose perigynia that usually have the apex turned to the back. Carex livida has longer perigynia that are consistently spindle-shaped. Carex hassei can be very similar and grows in the same habitat but has two stigmas per flower or, in southwestern Oregon, a mix of two-stigma and three-stigma fertile flowers. Carex klamathensis may have two stigmas on aborted flowers. |
