 species, especially as to the uninbers and size of the leaflets, and hairiness, but geutrally 

 Known by the single pair of pinnse and the axillary spines, which are rarely entirely wanting, 

 Wthough often some branches are without thern. It then resembles some forms of A, stn- 

 ^ow, but the pod is quite different. The following have been distinguished as species, but 

 are connected by too many intermediate foVnis to be separable even as varieties : — 1. J. de-
