| 説明 | Mountain sedge around the margin of Sunset Lake, Alaska Basin south of Hurricane Pass, Caribou-Targhee National Forest, Teton Range, Teton County, Wyoming. Mountain sedge is common in wetland settings in the Teton Range, but in this area this sedge species appears to replace water sedge (Carex aquatilis), which is otherwise common along lake margins in the Teton Range. The densely aggregated spikelets, do not have the long and slender architecture of those of water sedge. Also, the terminal spikelet often comprises many pistillate flowers, which contrasts to the strictly staminate terminal spikelet of water sedge. Perigynia are generally ellipsoid, which suggests var. bracteosa. |
