[Sedges: The Genus Carex East of the Cascade Mountains of Oregon and Washington]

Dunhead sedge growing on an open, gravelly-sandy slope upstream from Rock Springs at about 7600' near the junction of Trails #365 and #1964, Monument Rock Wilderness.........August 3, 2011.

Additional close-up photos of dunhead sedge as seen on a rocky ridge near 9000' on Strawberry Mountain, Strawberry Mountain Wilderness........August 3, 2011. The perigynia were photographed at the same location on August 19, 2011. The similar Tahoe sedge (Carex tahoensis - has larger, darker perigynia) can be found growing with dunhead sedge within eyesight about 10 miles away at Dixie Butte, so it is possible that the Tahoe sedge can be found in the area too. The penstemon in some of the photos is pincushion beardtongue (Penstemon procerus var. formosus).
