S. wetlandicus is a barrel-shaped cactus that is endemic to the Uinta Basin of northeastern Utah. Due to its location, it is threatened primarily by oil and gas development. This small cactus averages anywhere from 1.5-7 inches, though larger specimens have been observed. It generally has 6-14 white-gray radial spines and 3 central spines, which are longer than the radial spines. The cactus has gorgeous funnel-shaped flowers that vary from light pink to fuchsia with yellow stamens reaching up to 2 inches long. The fruit is short, barrel-shaped, and red or reddish grey when ripe (USFWS 2010).

Though morphologically similar to S. glaucus and S. brevispinus, it has been determined that all three are distinct species. The US Fish and Wildlife Service finalized this distinction in 2009. S. wetlandicus is typically larger than S. brevispinus, and has longer spines, however these two species do hybridize where their ranges overlap (Natureserve 2013, USFWS 2012).
