Uinta Basin Hookless Cactus

Sclerocactus wetlandicus is a rare species of cactus known by the common name Uinta Basin hookless cactus. It is endemic to Utah in the United States, where it is known only from the Uinta Basin. It may also be called the Pariette cactus, but this name is more appropriate for Sclerocactus brevispinus, the species endemic to the Pariette Draw of Duchesne County.

Sclerocactus wetlandicus is threatened by a number of processes and human activities. This plant is federally listed as a threatened species of the United States. Until 1989 it was included under the description of Sclerocactus glaucus, a threatened cactus. When it was separated and elevated to species status it retained the threatened designation. Sources vary in whether they recognize the separation from S. glaucus; Anderson (2001) does not.
