Type locality: Near Quito, Ecuador. 



Distribution: Ecuador. 



As observed by Dr. Rose in Ecuador in 191 8, this species is very variable in habit, 

 for when grown in the open it is low and bushy with rather small joints, but when grow- 

 ing in thickets it becomes tall and has large joints. About Huigra, where it is very 

 common, it is often spineless, and when the spines are present they are few and weak. 

 In southern Ecuador there is a plant which has small, red flowers Uke this species, but 

 the joints have stout subulate spines. 



Figure 194 represents a joint of a plant obtained in 1901 for the New York Botanical 

 Garden from M. Simon, of St. Ouen, Paris, France.
