The characters of the only two species of this genus hitherto 
published, as given by De Candolle, for I have no opportunity of 
consulting Cassini's original descriptions, are too brief for me to 
ascertain whether or not any of my four might be referred to one 
or other of them. The genus is very closely allied to Clibadium.
