Opuntia chlorotica gosseliniana is a variety of O. chlorotica (Ferguson, 1988). It is native to Mexico, and it barely reaches into the United States in far southern Arizona on land of the Tohono O’odham Nation. Plants may reach 3-ft tall (usually smaller), and are almost always tinted with pink or purple. The plants are smaller than those of vars chlorotica and santa-rita, and they have smaller, relatively slender fruit. This variety may have spines in all areoles, only in upper areoles, or in none at all. The slender spines vary from relatively short and stiff to long and flexible. Additionally, the spine color varies from cream to bright yellow and through shades of orange- and reddish-brown to nearly black.” Garden cultivar, ‘Tubac’, may be be a selection of O. chlorotica gosseliniana. Like O. chlorotica chlorotica, O. chlorotica gosseliniana has needle-like spines on older trunks and branches. Unlike O. chlorotica chlorotica, O. chlorotica gosseliniana can form multiple ascending branches. See the original description. O. chlorotica gosseliniana is diploid.
