opuntia

The cochineal insect is indigenous here, and is found upon the Cactus opuntia.

And presently Pablo noted something on the ground, at a distance, beside a clump of Opuntia.

I am greatly obliged to you about the Opuntia, and shall be glad if you can remember Catalpa.

Prickly-pear cactus (Opuntia lindheimeri) was common in those stands of mesquite, and we saw an occasional yucca tree.

The most widely distributed of the various groups of cacti is the prickly pear group of the genus Opuntia.
