The species is rarely more than 25 cm (10 inches) tall. Stems are green, flattened, up to 15 cm (6 inches) long. Flowers are magenta with yellow to magenta anthers and white styles. Fruits are tan, up to 3 cm (1.2 inches) long, dry when ripe.Parfitt, Bruce D. Rhodora. 99: 223, fig. 1. 1998.Earle, W. H. 1980. A new Opuntia identified in southwestern Utah. Saguaroland Bull. 34: 15.
Habitat
It grows in sunny locations in grasslands, on the edges of pinyon-juniper woodlands, on sandy or limestone soils.[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=242415220 Flora of North America, v 4 p 145]
Taxonomy
There is confusion concerning the correct scientific name. Specimens of O. pinkavae were distributed for years labeled as "Opuntia kaibabensis", a name that was never validly published.[http://opuntiads.com/O/opuntia-n-z/opuntia-p-r/opuntia-pinkavae/ Ferguson, David, & A. Dean Stock. Opuntia Web] Parfitt's original description coining the name Opuntia pinkavae and the treatment attributed to Pinkava in Flora of North America suggest that the name was offered as a replacement for another allegedly unpublished name, Opuntia basilaris var. woodburyi. However, the varietal name was indeed validly published, but chromosomal comparisons between it and O. pinkavae show that they are not the same taxon. Opuntia pinkavae remains an accepted name with no synonyms.{{Cite web|url=http://www.opuntiads.com/opuntia-n-z/opuntia-p-r/opuntia-pinkavae/|title=Opuntia pinkavae|last=|first=|date=|website=|publisher=|access-date=}}
