Opuntia diploursina A.D. Stock, N. Hussey & M.D. Beckstrom, sp. nov. is described as a new species of diploid, dry-fruited, prickly pear from the Grapevine Mesa region in south central Mohave Co., Arizona. It grows on alluvial gravel covered soil associated with Larrea tridentata (DC.) Coville, Yucca brevifolia Engelm. var.jaegeriana McKelvey and Yucca schidigera Roezel ex Ortigies. Opuntia diploursina is most closely related to tetraploid Opuntia erinacea Engelm. & J.M. Bigelow, but differs in spine characteristics, larger fruit and seeds and diploid chromosome number.
