Taxonomic CommentsThis record is for a broad treatment of Opuntia pinkavae, as recognized in Kartesz (1999), including Washington County, Utah plants that had been called O. basilaris var. woodburyi, though the combination had not been validly published according to Parfitt's (1997) description of Opuntia pinkavae. Kartesz (1994) accepted Opuntia basilaris var. woodburyi. Pinkava's treatment of Cactacae in FNA (2003, vol. 4) recognizes Opuntia pinkavae and says the name "replaces Opuntia basilaris var. woodburyi W. Earle which was never validly published." Stock et al. (2023) describe just the Washington County, Utah plants as Opuntia x woodburyi (Earle ex S.L. Welsh) Stock as a hybrid of O. aurea and O. pinkavae.

Rank ReasonsAside from the fact that it has a limited range in northwestern Arizona and extreme southwestern Utah, and the comment from Parfitt's paper which describes the species stating that Opuntia pinkavae is "not uncommon" within it's range, very little is known about this species.
Range Extent CommentsOpuntia pinkavae is not uncommon in northwestern Arizona [Coconino and Mohave Cos.] and extreme southwestern Utah at elevations of 1370-1560 m (Parfitt 1997).
Ecology & Habitat
Habitat
Opuntia pinkavae occurs at elevations of 1,370-1,560 m from the arid grasslands to the margins of pinyon-juniper woodlands. It is also found to persist in grasslands that have been damaged by excessive grazing and subsequent [soil] erosion. The substrate is usually fine, red sand (Parfitt 1997).
Reproduction
All Opuntias produce fruits that are dispersed by animals and many Opuntias are known to be self-dispersed, in addition (Valiente-Banuet and Godinez-Alvarez 2002).
