Pediocactus bradyi subsp. despainii is a rare species of cactus known by the common names Despain's cactus and San Rafael cactus.
The stems of Pediocactus bradyi subsp. despainii have a subglobose to obovoid to turbinate shape, measuring 3.8-6 cm in diameter and 3-9.5 cm in height and generally has no branches. [2] The roots are succulent and form clusters. It shrinks in size and disappears under the ground in dry and cold times, making it hard to find for most of the year. [3] Circular to oval areoles, varying in color from white to brown, may be either villous or glabrate. Smooth and relatively hard radial spines, numbering 9-15 per areole, spread out and are white, measuring 2-6 mm. Older plants may rarely have a small central spine of 4-8 mm. Flowers emerge near the stem tip, measuring 1.5-2.5 × 1.8-2.5 cm. Scales and outer tepals may display toothed, entire, or undulate characteristics. Outer tepals range in color from yellow-bronze to peach-bronze or pink with purple midstripes, measuring 4-10 × 3-6 mm, while inner tepals are yellow-bronze to peach-bronze (occasionally pink) and measure 6-12 × 4-6 mm. [2] Blooming occurs from April to May. The fruit starts green and dries to a reddish-brown, with a turbinate shape. [4]
It is endemic to the state of Utah in the United States, where it is limited to the San Rafael Swell in Emery County, Utah at elevations of 1450 to 2080 meters. [3]
There are two populations totaling about 6000 individuals. [5] It is threatened by a number of human activities. [6] It is a federally listed endangered species of the United States.
This cactus grows in the San Rafael Swell, a unique geologic feature in central Utah. It is an area with many rare native plants and has a high rate of endemism. The substrate is limestone and siltstone soil originating in the Carmel and Moenkopi Formations. The habitat is grassland with some junipers and pinyon pines.
This cactus was discovered in 1978 by Kim Despain and described to science in 1980. [6] It has sometimes been treated as a subspecies or variety of Pediocactus bradyi but is not generally accepted as such. It occurs generally near to its closest relative, Pediocactus bradyi subsp. winkleri. [2] Threats to this species include poaching, off-road vehicle use, gypsum mining, and petroleum exploration. [5]

It is limited to a specific type of soil, individuals are often spaced far apart, and the species is threatened by a number of human activities such as off-road vehicle use, poaching, and uranium mining. This is a federally listed threatened species of the United States.
Pediocactus bradyi is a very rare species of cactus known by the common names Brady's pincushion cactus, Brady's hedgehog cactus, and Marble Canyon cactus. It is endemic to Arizona in the US, where it is restricted to Marble Canyon in Coconino County, though its exact distribution is not generally advertised due to poaching concerns. It is limited to a specific type of soil, it has a small distribution, and the species is threatened by a number of human activities. This has been a federally listed endangered species of the United States since 1979.
Pediocactus knowltonii is a rare species of cactus known by the common names Knowlton's miniature cactus, Knowlton's pincushion cactus, and Knowlton's minute cactus.

Pediocactus simpsonii, known by the common names mountain cactus, snowball cactus, and mountain ball cactus, is a relatively common cactus that has adapted to survive in cold and dry environments in high elevation areas of the western United States. It can be found at higher elevations than any other cactus in North America. While not a landscape dominating plant, it is a relatively common species and the most common member of the genus Pediocactus. Because of its beauty and adaptation to cold environments it is sometimes grown by gardeners in areas that have few other choices due to the limited number of cactuses with cold adaptations. Like many cactuses its populations are sometimes threatened by this desirability due to the theft or removal of plants from the wild by collectors.
Pediocactus paradinei, also known as bristly plains cactus, Houserock Valley cactus, Kaibab pincushion cactus, Paradine cactus, and Park pincushion cactus is a rare species of cactus found in Arizona.
