THE CACT ACE AE. 



Type locality: California. 



Distribution: Deserts of southeastern California, northern Lower California, and 

 southern Nevada. 



Living plants from southern California, apparently referable to this species, do not 

 have any bristle-like radial spines, and the stout spines vary greatly in color, from red 

 to nearly white. 



The range of this species seems not to be very extensive ; Dr. Coulter records it from 

 New Mexico and Texas but this must refer to F. wislizcni. It is nearest F. wislizeni but 

 the spines are never hooked and the seeds are more shining, with stronger reticulations.

In America this species has long passed under the name of Echinocactus cylindraccus. 

 The above name, however, is much older and we are following Weber in using it. Weber 

 states that it has long been known as such in French collections and we believe that we are 

 justified in taking up the older name. 



It is also found in collections under the name of E. californicus and E. copoldi (Schu- 

 mann, Gesamtb. Kakteen 357. 1898). 



Echinocactus cylindraceus albispinus is in the trade (Grassner).
