Basic Description: Mound-forming herbaceous perennial to 3 cm in height from a taproot and heavily branched from the base. Persistent leaves and leaf bases cover the branch bases. Leaves are spatulate to oblanceolate, clothed in straight stiff hairs, and 3-20 mm long and 1.5 to 4 mm wide. Ray flowers are white, 1 to 2 mm long, sessile, and solitary at the ends of branches. The oblong bracts are densely pubescent at the tip. Flowers occur in May; fruits occur in June.
