Phenology
Flowers from May to early June.
Species range
A narrow endemic known only from an area straddling the Washington-Iron County line in southwest Utah. It occurs in the hills south-southwest of Newcastle, east of Old Irontown, in the Red Hills to the north and onto the southeast slopes of the Antelope Range (Franklin 2005).
Threats or limiting factors
There are three occurrences on Bureau of Land Management administered lands that are within a greenwood fuel cutting area where removal of overstory and on-ground disturbances are threatening the species' survival. Also on Bureau of Land Management lands there are several locations within one large occurrence where plants, over an area measurable in acres, are unexplainably stunted and sickly; this may be human-caused. Chaining at one location resulted in the loss of habitat (Franklin 1994 in Franklin 2005). Mining-related activities have also resulted in the loss of habitat (Franklin 1994 in Franklin 2005). Long-term effects of grazing, if any, are unknown (Kass 1995 in Franklin 2005). Off-road-vehicle travel may also pose a threat (C. Pontarolo, BLM, pers. comm.).
