Bngelmann, who described the species in 1848, based it on Wislizenus's specimen which came from near San Pablo, Chihuahua. In the Cactaceae of the Mexican Boundary Report, Engelmann again describes the plant and illustrates it. His illustrations, however, represent two species. We have denned the species in the same way that Dr. Engelmann did, for it will require further field studies along the border of Texas and Mexico to determine its exact limits; a second species may be confused with Fig. 45.—Echinocereus fendleri. Fig. 46.—Echinocereus lloydii. The type specimen consists of four flowers only. Wislizenus also collected two herbarium specimens of the stem of some other Echinocereus which were probably used by Engelmann in drawing up his original description. These, however, come from a different locality, Parras, and seem to represent a different species. On account of the delicious strawberry-like flavor of the fruit this plant is known as the strawberry cactus throughout southern Texas, where the fruit is much used for jams. According to Robert Runyon, it is also called the cob cactus about Browns- ville, Texas, because of the cob-like shape of its branches. Illustrations: Cact. Mex.
