Phenology

Most collections were made between July and September. 

Species range

Endemic to high elevations of the Tushar Mountains in the Southern Utah High Plateaus of Piute and Beaver Counties, central Utah; known from at least Mount Belknap and Gold Mountain.

Threats or limiting factors

This species occurs in high alpine, difficult-to-access areas, and there are not many threats. In the past, off-road-vehicle use was a potential threat to this species; however, the Travel Management Plan now in place for the Fishlake National Forest prohibits cross-country travel. Trampling by hikers does not appear to be a threat; in general, plants are not located close to trails, and the steep relief of the substrates on which it grows discourages exploration. Climate change is a threat, including droughts and rapid snowmelt (Alexander 2015).
