[Rushes: The Genus Juncus East of the Cascade Mountains of Oregon and Washington]

Close-up photos of the inflorescence of Colorado rush as seen at Fish Lake Campground, Steens Mountain, Harney County, Oregon..............August 31, 2011.

Colorado rush as seen along Summit Drive on the south slopes of Ninemile Ridge, Umatilla National Forest...........July 24, 2012. Note the long terminal bract in the photo at right and the shorter one in the photo at left.

What appears to be Colorado rush (in bud) as seen in meadows to the west of Big Creek Campground in the Logan Valley, Malheur National Forest............July 1, 2010. I've identified this as Colorado rush because the inflorescence is clustered together. If this isn't Juncus confusus, it might be Juncus filiformis which is similar but with the branches of the inflorescence more spread out?
