Mr. Harvey distinguished this plant from Pterygodium in à letter to Sir 
W. Hooker under the expressive name of Hippopodium (atratum) ; but 
I had already received it from Prof. Lehmann, with Ecklon's name of Ce- 
ratandra, which priority requires that I should adopt. The specific name 
atratum is best suppressed, as it is common to the whole genus, and the 
black colour when dried is one of the marks by which it is generally dis- 
tinguished from Pterygodium. Thunberg describes his P. atratum as 
having a crenulated labellum ; but I have seen no specimen which an- 
swers to that description.
