Thelesperma pubescens is limited to the Bishop Formation and perhaps adjacent areas in Uinta land Sweetwater Counties, Wyoming. This species has been separated from T. caespitosum by pubescence of the leaves (Dorn 1972). With the discovery of mixed populations of plants with pubescent and glabrous leaves plants on the Tavaputs Plateau, the separation of the 2 taxa is perhaps tenuous. Difference in habitat indicates there might be features other than pubescence that might serve to separate these plants. Regardless of the taxonomic status of these plants, the distribution on the Ashley National Forest remains the same (USDA, 2006).
Distribution & Occurrence
This plant occurs on the Badlands of Green River and Uinta Formations. In 1995 surveys were conducted by Fertig. Surveys took place in the Green River and Wyoming areas. Surveys by Forest Service and other botanists have also been conducted and additional populations have been found in the Bad Land Cliffs. The populations in Indian Canyon, Duchesne County are known only by a few collections where extensive survey has not been conducted (USDA, 2006).
