Prickly Pear
Prickly pears typically grow with flat, rounded cladodes (also called platyclades) armed with two kinds of spines; large, smooth, fixed spines and small, hairlike prickles called glochids, that easily penetrate skin and detach from the plant. Many types of prickly pears grow into dense, tangled structures.
"Opuntia engelmannii" is a prickly pear common across the south-central and Southwestern United States and northern Mexico. The nomenclatural history of this species is somewhat complicated due to the varieties, as well as its habit of hybridizing with "Opuntia phaeacantha".
