Plants densely cespitose, 3-8(-12) cm. Leaves mostly crowded at base of stems, margins conspicuously white-bristled, bristles (1.5-)2-4 mm. Heads usually 1. Peduncles 1-4 cm, usually ebracteate, occasionally bracteate. Flowering summer. Calcareous or clayey slopes; 1300-2000 m; Nev., Utah. Variety depressum was attributed to Arizona by J. T. Kartesz and C. A. Meacham (1999), but I have seen no specimen from there.
