The first 5 species here included are so alike that they require 

 care to sort : C. Iria, on the other hand, is placed by both Kunth 

 and Boeckeler with C. eleusinoides, which appears to me to differ 

 widely. Though the difference in inflorescence between C. Iria 

 and C. diformis distinguishes average examples readily, I have 

 met with large numbers of these two species cross-named m 

 herbaria ; and there are extreme forms of each species between 

 which the difference is merely one of very small degree. At all
