The Ecuadorian plant mentioned by Bentham is said to have 

 slightly smaller leaves than the original Colombian one. The author 

 has had no opportunity to examine or verify the itlentity of the Ecua-

 cal group it should have further study before its presence in the flora 

 of Ecuador can be regarded as established.
