Mammillaria is one of the largest genera in the cactus family (Cactaceae), with currently 200 known species and varieties recognized. Most of the mammillaria are native to Mexico, but some come from the southwest United States, the Caribbean, Colombia, Venezuela, Guatemala and Honduras. The common name "pincushion cactus" refers to this and the closely related genus Escobaria.
Pelecyphora, pincushion cactus or foxtail cactus is a genus of cacti, comprising 20 species.They originate from Mexico and the United States.
Pelecyphora missouriensis, the Missouri foxtail cactus and formerly Coryphantha missouriensis, is a species of low-growing North American cacti.
Pelecyphora vivipara is a species of cactus known by several common names, including spinystar, viviparous foxtail cactus, pincushion cactus and ball cactus. It is native to North America, where certain varieties can be found from Mexico to Canada. Most of these varieties are limited to the Mojave and Sonoran Deserts. The species epithet "vivipara" is due to the species' viviparous reproductive habit.
Escobaria robbinsorum is a rare species of cactus known by the common names Cochise pincushion cactus and Cochise foxtail cactus. It is native to southern Arizona in the United States, where it is known only from Cochise County, and northern Sonora in Mexico. There are scattered small occurrences on the north side of the border, and one known population to the south. Because of its rarity and a number of threats to remaining plants, the species was federally listed with a threatened status in 1986.
Pelecyphora sneedii is a rare species of cactus known by the common names Sneed's pincushion cactus and carpet foxtail cactus. It is native to the Chihuahuan Desert, where it occurs in scattered locations in New Mexico, Texas, and Chihuahua. Some plants occurring in Arizona may be included within this species. Botanical authors do not necessarily agree on the circumscription of this species. Most will agree at this point in the research, however, that there are two varieties of Pelecyphora sneedii, and that both are rare and endangered. The plant is popular with cactus enthusiasts and dealers because of its often petite size and tolerance for moderately cold climates. They have been overharvested from their natural habitat, the main reason why the two varieties, var. sneedii and var. leei, have been federally listed as endangered and threatened, respectively.
Lophocereus schottii, the senita cactus, is a species of cactus from southern Arizona and north-western Mexico, particularly Baja California and Sonora.
Pachycereus pecten-aboriginum is a columnar cactus plant native to Mexico. They can grow up to 15 m (49 ft) high.
