Plants glandular-pubescent, at least in inflorescences, white-farinose on involucral-bracts and calyces. Leaves longer than scape; blade broadly spatulate, margins dentate. Corolla-tubes 7–10 mm, length to 1.5 times calyx.


Phenology: Flowering summer.
Habitat: Cliffs, crevices, scree, around limestone outcrops
Elevation: 3100-3600 m

Discussion

Of conservation concern.

Variety nevadensis is known from the mountains of eastern Nevada and was initially distinguished by the relatively short scape overtopped by a basal rosette of leaves. Given the variation seen in the Primula cusickiana complex and the tendency of most Primula species to exhibit scape elongation throughout anthesis, this character is not sufficiently reliable to warrant species-level recognition.
