This species is represented by a considerable quantity of material, 

 but all is in a much broken condition. It is, of course, hazardous 

 to base species on limited material, since the leaves of existing 

 species are inclined to variability, and in the only fossil species 

 of which I have seen a large quantity of good material, i. e., 

 Gomhretum petraflumenMs Berry ^ from the middle Eocene of the 

 Mississippi embayment, the leaves are extraordinarily variable. 

 There is, however, a generic facies not easily mistaken. Leaves of 

 this type are not uncommon from the Eocene onward; indeed they 

 are foreshadowed during the Upper Cretaceous. Among previously 

 described forms the present species is much like C. incertmn Berry ^ 

 from the Miocene porcellanite of Siparia, Trinidad, British West 

 Indies. 



The genus contains about 150 existing tropical and often coastal 

 species, at least a third of which are natives of South America.
