General information

Sclerocactus wetlandicus is a federally listed as threatened species known from Duchesne and Uintah County, Utah. This rare cactus grows in gravel-covered clay hills, desert grasslands, and in saltbush and rabbitbrush flats. Contrary to the species "wetlandicus" epithet, this small barrel cactus is known from dry environments. Uinta Basin Hookless Cactus is an egg shaped barrel cactus with fragrant pink or purple flowers and spines which can obscure the stem. In 2009, the Fish and Wildlife Service (FWS) officially recognized Sclerocactus wetlandicus as a species from the taxonomic split of Sclerocactus glaucus into three distinct species, S. brevispinus, S. glaucus, and S. wetlandicus. (FWS, 2010)
