The two preceding species are remarkable for tlieir inflores- 

 cence; but not having seen their fruit, I cannot be certain as 

 to their being correctly placed near the Aleticidosa-, with which 

 they appear to have considerable affinity in other respects.

In this group I include all the unarmed species with one 

 pair of pinnae and several pair of leaflets, and a racemose in- 

 florescence, which have neither the stellate hairs of the i^/'/- 

 dotcB, nor the reversed strigse of the Ohstriijoscp. The spe- 

 cies, mostly Brazilian, are numerous and very difficult to 

 arrange in the present state of our acquaintance with them. 

 It is probable that when the fruit of more species is known, 

 these and the Pectinatce may be broken up into better char- 

 acterized and more natural series ; but at present I cannot 

 discover any collateral character to distinguish those which 

 have the articulate pod from the inarticulate ones, witliout 

 seeing the pod itself. Of the five following groups, derived 

 chiefly from the foliage, the first two contain certainly species
