Opuntia cochenillifera, prickly pear.

>

Opuntia cochenillifera, prickly pear. Note the numerous perianth segments and stamens and several green stigmas in this typical cactus flower. The ovary is sunken into the stem at the bottom of the photo. Also visible here are several areoles bearing bristles that would persist as the fruit matures.
