Opuntia rastrera Opuntia rastrera Opuntia rastrera is a prickly pear which grows in the Mexican state of San Luis Potosí. It is known in Spanish as cuija, although that name can also refer to other cactuses such as "Brasiliopuntia". "Opuntia rastrera" can be found in bajada, hill-piedmont, and interdune habitats in locations such as the Mapimi biosphere reserve, where it is sometimes the most common cactus in a given location, or sometimes a secondary cactus. In order to germinate, the seeds require a dormancy period of at least a year. As with other "Opuntia" species, mechanical or chemical scarification does not seem

Along with "O. stricta","O. bentonii" was one of the pest pears of Australia in the early Twentieth Century. Like so many "Opuntia" species, "O. bentonii" has been mistaken for a coastal form of "O. lindheimeri" in Texas, but there are sustained differences. For instance, "O. bentonii" plants are often less than 60 cm in height and the fruit is more globular
