These photos show close-up views of the perigynia of what appears to be blister sedge. Photographed at Muddy Meadows on the northern slopes of Mt. Adams.........August 7, 2005.

The 4 photos above show close-up views of the spikelets of what appears to be blister sedge. Photographed at Muddy Meadows on the northern slopes of Mt. Adams.........August 7, 2005.

The photo above shows the male (upper) and 2 female spikes (lower) of inflated sedge as seen in a vernal riparian area in the public hunting area to the west of Lakeside Road in Conboy Lake NWR to the southeast of Mt. Adams.........July 16, 2008. The habitat of this sedge is at the edge of the large lake that forms in this area during the late winter and early spring (probably no more than a foot deep at this site at that time) and dries up by early June.

The 6 photos above show close-ups of what may be blister sedge as seen in wetlands along Forest Road K1000 to the west of the Mt. Adams Highway..........August 11, 2008. If this is indeed blister sedge, it is not a typical specimen. The spikes measure up to 10 cm long on a plant up to a meter and higher in height.
