Taxonomy
The first description as Cereus saxicola was published in 1893 by Thomas Morong.[5] 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 and Cereus rhodoleucanthus. As of November 2025[update], Monvillea saxicola is the currently accepted name in Plants of the World Online.[2]
Distribution
Monvillea saxicola is widespread in southwestern Brazil and northeastern Argentina at altitudes of 300 to 900 meters.[citation needed] It is also found in Paraguay.[2]
