Plants (0.5-)1-3 dm. Aerial flow-ering stems sparsely glandular proximally. Inflorescence branches glandular prox-imally. Flowers 2-3 mm. Achenes 1.8-2.5 mm. Flowering Jun-Sep. Sandy to gravelly flats and slopes, saltbush, sagebrush, and mountain mahog-any communities, pinyon-juniper and montane conifer woodlands; 2100-3200 m; Nev. Variety toiyabense is totally isolated from all known populations of var. esmeraldense. In Nye County, it is found in the Toiyabe, Toquima, and Monitor ranges, where it can be locally common. To the east and north, it is locally infrequent in the Shoshone (Lander County) and Independent mountains (Elko County). It may well be more widely distributed than reported here, and not worthy of its current 'sensitive' status.
