has been well observed by Seringe that characters derived from the leaves, unless 

 supported by differences in the fruit, are insufficient to distinguish from one another 

 the species of this difficult genus. Even the fruit seems liable to vary, though within 

 certain limits only, and it will be found to afford the best characters for the discrimi- 

 nation of the species.
