A species never rediscovered and known only from the original im- 

 mature specimen secured without certain record of localitj^ by Hum- 

 boldt & Bonpland. The type is in the Museum of Natural History 

 at Paris and a (rather poor) photograph of it, taken by the writer in 

 1905, is now in the Gray Herbarium. From this it has been possiV)Ie 

 to check and verify most of the characters of the original description, 

 and to make reasonably sure that the species is distinct from any 

 other known in Colombia. On the other hand, the precise position 

 in the genus is still doubtful. DeCandolle (whose knowledge of the 

 Compositae of Humboldt & Bonpland has in several other cases proved 

 defective or erroneous) places this species in § Cylindroccphala, but 

 Kunth, who certainly must have had access to the original material, 

 grouped it with species of § Svbhnbricafa, where for the present it 

 seems best to give it provisional location.
