Seedling and Fruit Characters. 



The following key has been constructed mainly from 

 characters of the s4eds and seedlings. In several instances 

 the number and behaviour of cotyledonary traces would 

 have been of service, but as such' characters cannot be used 

 outside the laboratory those of the fruit have been included 

 as being of more practical importance in determining the 

 identity of species in the forest. 



ENDOSPERM EQUABLE. 

 Cotyledons persistent. 



Seeds flat, thin (2 mm.) ..J D. lianliicri. 



Seeds wedge-shaped. 

 Fruit-calyx large, woody, seg- 

 ments acute, first epicotyledon- 

 ary leaf small, only 2 mm. long/.D. Ebenuni.
