Distribution, systematics and endangerment
Mammillaria neopalmeri is common in the Mexican state of Baja California on the islands of San Benito and Guadalupe .
It was first described as Cactus palmeri in 1894 by John Merle Coulter . Friedrich Bödeker placed the species in the genus Mammillaria in 1933 . However, this recombination was invalid according to Article 53.1 of the International Code of Botanical Nomenclature , since Georg Albano von Jacobi had already described a Mammillaria species with the name Mammillaria palmeri in 1856 . Robert T. Craig therefore gave the species the replacement name Mammillaria neopalmeri in 1945 .
Synonyms are Mammillaria dioica var. Neopalmeri (RTCraig) Neutel. (1986), Mammillaria palmeri (JMCoult.) Boed. (1933, nom. Inval. ICBN -Article 53.1) and Bartschella palmeri (JMCoult.) Doweld (2000).
In the Red List of Threatened Species of the IUCN , the species is listed as " Least Concern (LC) ". H. listed as not endangered.
