Collected by J. N. Rose and George Rose at Huigra, Ecuador, August to November 

 1918 (No. 22127). 



This species is very common on the dry hills both below and above Huigra, Ecuador, 

 ranging from about 3,500 to 6,000 feet, where it is the most conspicuous plant in the land- 



scape 



It is associated with a Furcraea, several 



species of Opuntia, a Batthinia, and a Zanthoxylum. 

 It is frequently overrun by vines, such as species 

 of Passiflora and Ipomoea. 



It overlaps the lower range of an undescribed 

 species of Trichocercus and has been frequently 

 confused with that species. (See page 135.) 



This plant is named for Dr. F. W. Coding, 

 United States Consul-General at Guayaquil, 

 Ecuador, a well-known entomologist, who assisted 



Dr. Rose in his botanical explorations in Ecuador.
