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 defined 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.
