Cloud sedge on a talus slope in Alaska Basin on the west side of Buck Mountain, Teton Range, Teton County, Wyoming. Payson sedge ranges from bunched to mat-forming because of its rhizomatous growth habit. The dark pistillate bracts and ovate perigynia often with a submarginal vein are in part distinguishing of this sedge species.

Cloud sedge on a talus slope in Alaska Basin on the west side of Buck Mountain, Teton Range, Teton County, Wyoming. Like Carex microptera, smallwing sedge, in having tight globose heads of spikelets, each gynecandrous, and perigynia close to 1.5 mm wide. Cloud sedge has a conspicuously long perigynium beak, averaging about 2 mm long. Also, the perigynia in this area average about 5-6 mm long, maybe slightly longer than the average for Carex microptera perigynia.

Engelmann sedge forms lawns or carpets in swales on moraine talus in the Alaska Basin area including here on the west side of Buck Mountain Pass, Teton Range, Teton County, Wyoming. The rhizomatous growth habit, terete narrow leaves (terete at base), a single ovoid spikelet terminating each flowering stem, pistillate flowers with three style branches and subtended by a large acuminate scale are distinguishing of this alpine sedge. A population with mature (or evident) staminate flowers confined to the tip of the single spikelet was sitting in a more protected part of a swale.

Cloud sedge abundant on moraine talus in the Alaska Basin area including here on the west side of Buck Mountain Pass, Teton Range, Teton County, Wyoming. Much like Carex microptera, smallwing sedge, in having tight globose heads of spikelets, each gynecandrous, and perigynia close to 1.5 mm wide. Cloud sedge has a conspicuously long beak, averaging about 2 mm long. Also, the perigynia in this population average about 5-6 mm long, perhaps slightly longer than the average for perigynia of Carex microptera.
