On account of the somewhat imperfect material I am doubtful as to the true 
affinity of this species. In appearance it resembles C. amabdilis, Mill. Arg-, sso 
which, and indeed trom all the other African species known to me, it may be re 
guished at once by the orbicular unfringed scales on the upper surface of the 
leaves.
