Turbinicarpus schmiedickeanus

Turbinicarpus schmiedickeanus is a small cactus in the family Cactaceae, native to northeastern Mexico. It is endemic to the states of Nuevo Leon, San Luis Potosi and Tamaulipas, where it grows in hot deserts. Plants of the World Online, as cited in March 2022, accepts thirteen subspecies of it, many of which were once treated as separate species, among them andersonii, bonatzii, dickisoniae, flaviflorus, gracilis, jauernigii, klinkerianus, macrochele, rioverdensis, rubriflorus, sanchezii-mejoradae, schwarzii and the nominate subspecies schmiedickeanus. The species is threatened by habitat loss, and it has been assessed for the IUCN Red List of Threatened Species in 2017. The source article is brief, so this entry records only what it states about the name, the subspecies, the range, the habitat and the threat.
