A species never rediscovered and known only from the original im- 
mature specimen secured without certain record of locality 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 possible 
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 § Cylindrocephala, but 
Kunth, who certainly must have had access to the original material, 
grouped it with species of § Subimbricata, where for the present it 
seems best to give it provisional location.
