Abstract
Weberocereus alliodorus, a new cactus species from the southern slopes of the Sierra Madre del Sur, Oaxaca, Mexico, is described, illustrated, mapped, and compared to its putative closest relative, W. glaber. The new species is characterized by its three-winged stems with rigid and setose, relatively long spines, relatively large flowers, and fruits with a penetrating onion-like odor.
Resumen
Se describe, ilustra y mapea a Weberocereus alliodorus, una nueva especie de cactus de Oaxaca, México, y se compara con W. glaber, su supuesto pariente más cercano. La especie nueva se caracteriza por sus tallos trialados con espinas rígidas y setosas relativamente largas, por sus flores relativamente grandes y por sus frutos con un olor penetrante reminiscente a la cebolla.
