A considerable number of these genera, especially the larger 

 and widely spread ones, are much less systematically isolated, less 

 strictly limited than the American ones. Antidesma, Ostodes, 

 Claoxylon, Mallotus, and perhaps some others are centres round 

 which several others might be grouped, as we have previously 

 shown in Phyllanthus and Exccecaria ; and even several of the 

 smaller apparently isolated ones are more frequently intermediates 

 between or distantly connected with others than in America, 

 although no doubt there are several in Asia as well as in Africa 

 to which no affinity nearer than the general tribual connexion can 

 be traced. 



Analyzing the above list, we have, in the first place, three northern
