Opuntia phaeacantha centers, and sometimes peach, pinkish or reddish overall. The edible fruits are red or purple with green flesh. The pads and fruit bear tiny glochids which can lodge in the skin and cause irritation. This plant, like other "Opuntia" species, is attacked by cactus moth. Older names for this species, and names for old species which are now considered variants of this species, include plateau prickly pear, brown-spined prickly-pear, Mojave prickly pear, and Kingman prickly pear. The species is widespread, from California to Texas to Colorado and New Mexico, and into Mexico. There are multiple variations and perhaps these will
Opuntia arenaria strongly deflexed and much shorter. Overall, plants (clumps) of cladodes may be 20–30 cm across and about 4–8 cm tall. Fruits are small, about 2.5 cm. Opuntia arenaria Opuntia arenaria was considered a variety of "O. polyacantha" by many botanists, and is still treated that way in the Flora of North America. However, "O. arenaria" is diploid and "O. polyacantha" is tetraploid. It was described by Engelmann in 1856. "Opuntia arenaria" can grow in soil that is essentially pure sand. It has rhizomes up to 1.5 m long that give rise to above ground shoots with small cladodes that are
