61. BEAVERTAIL CACTUS Cactus Family _Opuntia basilaris_
One species of cactus that at first sight does not seem to be a cactus is the Beavertail, for it is lacking the long spines characteristic of most cacti. Upon close examination, however, you will find that it is protected by numerous, fine spines. The name of this species is derived from its flat stems shaped somewhat like a small beaver’s tail. The conspicuous magenta flowers mark this species as one of the most beautiful in the park. The fruit of this species is important as animal food, especially for chipmunks and ground squirrels.
62. BUCKHORN CHOLLA CACTUS Cactus Family _Opuntia acanthocarpa_
The Cholla (pronounced Choya) Cactus is the only “tree” cactus found in Zion. It is fairly common in the Lower Sonoran Zone, especially in Coalpits Wash. Strangely enough this plant is a favorite nesting place of some desert birds, including sparrows, wrens and finches. The spreading branches seem to reach out and grab the careless hiker, and the barbed spines stick so fast in the flesh that the joint of the plant is separated from the main stem before the spines can be withdrawn. Cholla blossoms come in many shades of color with the accent on yellows and reds.
63. ENGLEMANN PRICKLYPEAR CACTUS Cactus Family _Opuntia engelmannii_
As one of the largest of the flat-jointed or Pricklypear Cacti of Zion, this species is fairly abundant in Zion Canyon and is probably the most frequently observed species because of its dense growth in certain habitats and its fairly immense size as well as its colorful display of blossoms. It is locally called Elephant Ear Cactus. In June in produces large yellow flowers, very waxy in texture.
(See Figure 64 for information concerning the fruit of this cactus.)

64. CACTUS FRUIT Cactus Family _Opuntia engelmannii_
The fruit of the Engelmann Pricklypear Cactus is similar to the fruits of many other species of cacti; it is conspicuous, being deep red in color and about the size of a large Crab Apple. It is called Tuna or locally “Cactus Apple” and ripens as early as June but more abundantly during July.
Indians of the Southwest use this fruit as an important item of their diet. Many people living in the desert have come to learn that this cactus fruit makes excellent jellies and candies. It is also feasted upon by several rodents, especially the Antelope Ground Squirrel.
