Several photos of Payson's draba as seen amongst granitic rocks on windswept tundra ridgelines high atop Tiffany Mountain, Okanogan-Wenatchee National Forest.......July 27, 2018. The stems, pedicels and sepals of this species are pubescent while the ovate fruits are covered with both simple and 2-6 rayed hairs. The leaf margins are hairy but the hairs are not crisped.
