10 cm. long; flowers light yellow, small; fruit globose, i to 1.5 cm. long, dry; seeds corky. 



Type locality: Brazil, according to Haworth, 

 but erroneously. 



Distribution: Western Argentina. It has also 

 been referred to Brazil and Chile, but surely not 

 found in Brazil, and we should not expect it to 

 inhabit Chile. 



The plant figured by Nicholson (Diet. Gard. 

 2* f- 755) as O. platyacantha hardly belongs here. 



O. glomerata, which is common on the dry 

 hills about Mendoza, is very variable, especi- 

 ally as to whether it is spine-bearing or not; 

 while the spines — which are really not spines but 

 thin ribbon-like processes — vary much as to their 



irkinsrs. and leneth. These variations

species. Dr. Rose, who visited the region m 

 which this species grows, found wide variation in 

 the size of the joints, as well'as in the absence or 

 presence of spines.

Opuntia polymorpha Pfeiffer (Enum. Cact. 103. 1837), and Opuntia turpinii poly- 



Dyck. 1849. 71. 1850) are usually given as synonyms 

 of Opuntia diademata, but none of them was actually published. Opuntia polymorpha 

 Pfeiffer was used by Pfeiffer as a synonym for Cereus artic 



Tephrocactus andicolus, T. calvus, and T. platyacanthus, 

 without descriptions, are referred here by inference.
