Additional close-ups of what appears to be lakeshore sedge growing at a seep above 7000' along the Roads End Trail (near the junction with the Onion Creek Trail, Strawberry Mountain Wilderness...............August 3, 2011. The photos of the perigynia and greenish-colored spikelets were taken at the same location on August 19, 2011. Note the terminal male spike and lateral female spikes. Two stigmas are present, the perigynia lack reddish spots (excluding the beak tip), and note also the hyaline membranes at the top of the leaf sheath fronts. If these photos aren't of Carex lenticularis var. lipocarpa, please let me know.

Close-ups of lakeshore sedge growing at about 7400' along the western shore of Fish Lake, Steens Mountain, Harney County, Oregon...............September 3, 2011. The veins in the perigynia can be seen in the lowest photo, which helps distinguish from the similar
water sedge (
Carex aquatilis var.
aquatilis) which essentially has veinless perigynia.
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 photo above shows a close-up of the upper two spikelets within the inflorescence of lakeshore sedge. Photographed at Willard Springs in Conboy Lake NWR......................July 31, 2008. The elongated uppermost spikelet consists of male flowers while the lower spikelet is female.
The photo above shows a close-up of a female spikelet of lakeshore sedge. Photographed at Willard Springs in Conboy Lake NWR......................July 31, 2008. 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.
