Opuntia basilaris Opuntia basilaris Opuntia basilaris, the beavertail cactus or beavertail pricklypear, is a cactus species found in the southwest United States. It occurs mostly in the Mojave, Anza-Borrego, and Colorado Deserts, as well as in the Colorado Plateau and northwest Mexico. It is also found throughout the Grand Canyon and Colorado River region as well as into southern Utah and Nevada, and in the western Arizona regions along the Lower Colorado River Valley. "Opuntia basilaris" is a medium-sized to small prickly pear cactus tall, with pink to rose colored flowers. A single plant may consist of hundreds of fleshy, flattened pads.
Opuntia bentonii Opuntia bentonii Opuntia bentonii was proposed by some botanists to be a synonym of "Opuntia stricta". However, "O. bentonii", which grows in Texas, is separate and distinct from "O. stricta." "O. bentonii" was clearly described by Griffiths in 1911. 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
