Opuntia diploursina Great Basin deserts, is suspected to be a stabilized allopolyploid derived from "O. diploursina" and "O. basilaris". Some "O. diploursina" x "basilaris" progeny resemble "O. basilaris" var. "treleasei" (2n=33), an endemic species of California. Opuntia diploursina Opuntia diploursina is a species in the Cactaceae family, that grows near and in Lake Mead National Recreation Area and northward across Nevada's Mormon Mesa, into Utah. This species is a close relative and probable ancestor of "Opuntia erinacea", but "...differs in minor spines more closely appressed to pad surface, spines smaller in diameter and more flexible, inter-areolar distance less, upright growth habit, larger
Opuntia ficus-indica the wild origin of "O. ficus-indica" is likely to have been in Mexico due to the fact that its close genetic relatives are found in central Mexico. "Opuntia ficus-indica" is polyploid, hermaphrodite and autogamous. As "Opuntia" species grow in semi-arid environments, the main limiting factor in their environment is water. They have developed a number of adaptations to dry conditions, notably succulence. The perennial shrub "Opuntia ficus-indica" can grow up to 3-5m height, with thick, succulent and oblong to spatulate stems called cladodes. It has a water-repellent and sun-reflecting waxy epidermis. Cladodes that are 1–2 years old produce flowers, the
