Abstract:

A new species of Phlox is described from a series of peaks and ridgetops in the Blue Mountains of southeastern Washington state. Phlox solivagus M. Mayfield & M. Darrach, sp. nov., is narrowly restricted to exposed rocky sites and flowers in mid–late spring when easy access by collectors can be obstructed by snow on surrounding slopes. This species is a highly distinctive caespitose perennial Phlox with lanate vestiture on stems and leaves, thickened leaves with involute margins (yielding a prow-shaped apex), and inflorescence herbage densely covered with gland-tipped trichomes. The new Phlox is described and discussed with respect to species to which it is similar, and a key to Phlox species of the northern Blue Mountains is provided.
