ECHINOCEREUS.

what flabby, dull green; areoles 2.5 cm. apart; radial spines unequal, usually less than 12 mm. long, 

 acicular, at first yellowish, becoming brownish; central spine solitary, usually elongated, nearly 

 terete, 3 to 5 cm. long; flower purple, 7.5 cm. broad; perianth-segments nearly oblong; style cream- 

 colored, a little longer than the stamens; fruit globular, juicy, edible. 



Type locality: Near San Pablo, south of Chihuahua, Mexico. 



Distribution: Northern Mexico, New Mexico, and southern Texas. 



There has always been more or less uncertainty about this species. Engelmann, 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 it.

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.
