Distribution and systematics
Cumulopuntia crassicylindica is common in the Peruvian region of Arequipa .
It was first described as Tephrocactus crassicylindricus in 1956 by Werner Rauh and Curt Backeberg . Friedrich Ritter placed the species in the genus Cumulopuntia in 1981 . However, its recombination was invalid according to the rules of the ICBN , as reference was made to the basionym without specifying a page number. This took Urs Eggli after a year of 2005.
A nomenclature synonym is Opuntia crassicylindica (Rauh & Backeb.) GDRowley (1958).
