Abstract

Opuntia megarrhiza Rose (Cactaceae) is a species endemic to central San Luis Potosí, Mexico that, since originally described in 1906, has remained poorly understood. A comprehensive morphological description is presented and its presumed taxonomic affinity withO. chaffeyi is discussed. General accounts of its distribution, ecology, uses, and conservation status are presented.
