Taxonomy edit

The first description as Cereus saxicola was published in 1893 by Thomas Morong.[4] The specific epithet saxicola is derived from the Latin words saxum for 'rock' and -cola for '-dwelling' and refers to the rocky habitat of the species. Nigel Paul Taylor placed the species in the genus Praecereus in 1997. Taxonomic synonyms include Cereus cavendishii Monv. (1839) and Cereus rhodoleucanthus K.Schum. (1899).
