General: Clokey Catchfly (Silene clokeyi) is a low-growing, high-elevations species endemic to the Spring Mountains where it grows up from among stones on the ground. The pink-and-white striped, urn-shaped corolla tube with notched pink petals identify this unusual plant.

Clokey Catchfly is an uncommon component of the high-elevation vegetation communities on rocky summits in the Hudsonian (Bristlecone Forest) and Arctic (Alpine Tundra) life zones. This species is endemic to the Spring Mountains and is only found at the highest-elevations atop Mt. Charleston, Mummy Mountain, and Mt. Potosi. While this species can be locally common, it is a rare plant because it occurs only atop the Spring Mountains.
