Description

Primula domensis is endemic to the slopes of Notch Peak in Millard County, Utah. This plant occurs on rocky slopes or cliffs composed of limestone at 8,500 to 9,000 feet elevation. It flowers May through June and might be noticed by its lavender to rose colored corolla and tube. 

Diagnostic characteristics

Primula domensis is similar to P. nevadensis and P. maguirei. Primula nevadensis has more wedge-shaped, dentate leaves that overtop the inflorescence when compared to P. domensis. Compared to P. maguirei, P. domensis has much larger calyces (8-12 mm vs 5.5-7.5 mm long), more consistently toothed leaves, and shorter corolla tubes in proportion to the calyx length. 

Species range

Basin and Range; narrow endemic known only from the slopes of Notch Peak, House Range, north central Millard County, Utah.

Threats or limiting factors

Mining activities pose a potential threat. Inaccessibility of the habitat makes recreation a minor concern (Franklin 2005).
