The Details

Opuntia diploursina was described from near Meadview, AZ. It has similarities with O. polyacantha erinacea; however, there are differences between the two prickly pears. A major difference between the two cacti is that one is diploid and one is tetraploid. Other differences such as seed size  and shape also exist. The plants can be up to half a meter tall with up to 5-6 ascending cladodes but are often less than 12-inches tall. The original authors proposed that O. diploursina represents a diploid ancestor of O. polyacantha erinacea and that O. diploursina is distinct from the similar O. trichophora. Hybrids between O. basilaris and O. diploursina have been reported. Read the original description. O. diplourisna is diploid.
