Echinocactus peninsulae Weber, Bull. Mus. Hist. Nat. Paris 1: 320. 1895. 

 Simple, erect, 2.5 meters high, clavate to cylindric; ribs 12 to 20, prominent; areoles 4 cm. apart 

 or even less in old plants; spines red with yellow tips; radial spines 11, spreading, straight, terete, 

 more or less annulate, the lower ones stouter and more colored; central spines 4. 



Type locality: Lower California, but no definite locality cited. 



Distribution: Southern Lower California. 



Engelmann and Weber seemed to have been in agreement regarding this species being 

 new, but Engelmann's name (Contr. U. S. Nat. Herb. 3: 361. 1896) was based on Gabb's 

 specimen (No. 11), now preserved in the Missouri Botanical Garden, while Weber's name 

 is based on Diguet's plant. The plants of these two collections may or may not be con- 

 specific. We have seen only Engelmann's specimen which we have used in making our 

 illustration. 



In December 1920, Dr. William S. W. Kew sent us fruit and a small living plant from 

 near Boca de Guadalupe on the west coast of Lower California which we believe belongs 

 here. His plant is less than 10 cm. high with 8 broad ribs; young areoles brown-felted, 

 circular; radial spines spreading, brownish or white; central spines 4, grayish brown, the 

 lower one flattened, strongly hooked, annulate; flowers yellow; fruit yellowish, 2.5 cm. 

 long, bearing broad rounded scales; seeds 2 mm. long, reticulate. The plant is known as
