Species about 20, in tbe tropics of tlie Old World, rare in Africa, absent fron^ 

 Annrica. 



Tbe genus Excoeearia, ns here understood, is distinguisbed from Sapium by 

 baviiig only lateral inflorescences. Tbe solitary Tropical African species lias, bowever, 

 been reterretl by Pax and K. HofFipanii, as a distinct section, to Spirostachys, 

 Sond., from wliicli it differs in baving free tilanients. Miiller lias included botli 

 Sapium n\\(\ Spirostacfiys \\\\i\k:v Exc(jecaria; Kiint/.e ba3 included bolb .EjrccecariVt 

 and Spirostachys under Sapium. Benibani, wbile including Spirostachys under 

 Exccecaria, lias kept tbe latter genus apart from Sapium because in Excaecaria, as 

 understood by bim, tbe calyx is more deei)ly lobeil tiian it is in Sapium.
