﻿358 MR. G. BENTHAM ON THE MIMOSE^E. 



r 



may "be referred the absolute identity of a few tropical species in the New and the Old 



World. 

 I now proceed to the enumeration of the genera and species of Mimosese more or less 



known to me, with short diagnoses of the more essential distinctive characters, referring, 

 for more details as to genera, to our ' Genera Plantarum,' vol. i. pp. 462 and 588, and, as 

 to species, to the various works quoted under each. I have, however, given the post- 

 Linnean synonymy as complete as I have been able to ascertain it, and added fuller 

 descriptions to the several species now first established as new.
