Prickly Pear Cactus Genus Opuntia Most prickly pear cactus have yellow, red or purple flowers, even among the same species. They vary in height from less than a foot (Plains, Hedgehog, Tuberous) to 6 or 7 feet (Texas, Santa Rita, Pancake). Pads can vary in width, length, shape and color. The Beavertail, Santa Rita and Blind Pear are regarded as spineless, but all have glochids. Prickly pear cactus represent about a dozen species of the Opuntia genus (Family Cactaceae) in the North American deserts. All have flat, fleshy pads that look like large leaves. The pads are actually modified branches or stems that serve several functions — water storage, photosynthesis and flower production. Chollas are also members of the Opuntia genus but have cylindrical, jointed stems rather than flat pads. Like other cactus, most prickly pears and chollas have large spines — actually modified leaves — growing from tubercles — small, wart-like projections — on their stems. But members of the Opuntia genus are unique because of their clusters of fine, tiny, barbed spines called glochids. Found just above the cluster of regular spines, glochids are yellow or red in color and detach easily from the pads. Glochids are often difficult to see and more difficult to remove, once lodged in the skin. http://bit.ly/1ewHcCR
