Since I proposed the division of tbis vast genus into three sections or subgenera, I have seen the ripe 



unknown : and 



culate and continuous valves, which I had already been obliged to give up in respect of some species of 



group MeticuloscB 



of the section 



articulate 



Habbasia. In some cases the pod (within the constantly continuous persistent margin) 



otherwise 



be group of Spicifl^ 

 Habbasi(B. with the 



Ameriaj and the isomerous stamens of Eumimosa. I have therefore been obliged to reduce the number of 



distingu 



or twice that of the 



divisions of the corolla — a character which I have found absolutely constant, except perhaps in a single 



(M, 



Habbasia and Ameria, and the new lisrhts thrown 



■ 



many species by the numerous additional specimens brought under examinationj as well as a considerable 



number of new species, have occasioned several modifications in the subordinate groups I had proposed. 



It may be therefore useful to prefix to the detailed enumeration of species the following general summary 



of the groups or series, neglecting occasional exceptions, to be specially mentioned in the course of the 

 enumeration. 



Sect. 1. Eumimosa. Stamina numero petalorum agualia. — Species 1-130.
