tion of the radicula is of no importance towards distinguish- 
ing the divisions of the same order, nor even probably of 
distinguishing divisions into natural genera. Whether 
more dependence can be placed on the number of parts, or 
in the presence or absence of an arillus, is not yet ascer- 
tained. Under these circumstances, as Decandolle includes 
only twenty-five species in the whole of this division, he 
probably would have acted more judiciously, in considering 
the whole as a genus, rather than as a natural order, ex- 
cluding only the Eheherga, which consists of one species, 
more nearly, perhaps, allied to the Aurantiacetje^ than to 
the MeliacecE.
