The photo above shows a close-up of the inflorescence of lakeshore sedge. Photographed at Willard Springs in Conboy Lake NWR..........July 31, 2008. Although nibbled off by an herbivore here, the leaf-like bract below the lowest spikelet is typically longer than the inflorescence. The elongated uppermost spikelet consists of male flowers while the lower spikelet is female. The distinctive scales at the base of each perigynia are dark brown or blackish and readily visible here.

The perygnia are entirely green except for the brownish tip. The scales covering the female perigynia are shorter than the perigynia and brownish to black as seen here.

What appears to be Kellogg's sedge lining a small pool in Bullion Basin at the eastern edge of Crystal Lake Ski Area, Baker-Snoqualmie National Forest.............August 26, 2014. Mountain sedge (Carex scopulorum var. bracteosa) could be there, but its bracts and perigynia should be blacker. These plants look like they could be rhizomatous (without digging them up) which would suggest water sedge (Carex aquatilis), but none have been collected in the area.
