Raynold's Sedge: Carex raynoldsii (Synonym: Carex lyallii)

Raynold's sedge as seen at a vernally moist swale where the snow lies late into the summer at about 8700' along the North Loop Road about three-quarters of a mile below the Kiger Gorge Overlook Road, Steens Mountain summit, Harney County, Oregon................August 31, 2011.

Close-ups of the inflorescences of Raynold's sedge as seen at a vernally moist swale where the snow lies late into the summer at about 8700' along the North Loop Road about three-quarters of a mile below the Kiger Gorge Overlook Road, Steens Mountain summit, Harney County, Oregon...........August 31, 2011. Note the 3 stigmas, the dark perigynia scales contrasting with the greener perigynia, the long bract subtending the lowest lateral spike and the white, membranous sheath to the subtending bract. I initially thought these might be Carex heteroneura but note that the uppermost spike appears to be androgynous (male) while C. heteroneura is gynecandrous. C. raynoldsii is androgynous with expanded perigynia but I believe these plants are earlyin the bloom period and thus the perigynia are flattened and thus haven't begun to expande yet.
