PERKINS THE LEGUMTNOSAE OF PORTO RTCO. 213 



The differences in the pod and secd^ of R, phascoJ aides and R. minima are quite strik- 

 ing. The pod of the former is constricted between the seeda, and the seeds are black 

 I with a Kcarlet-yelluw ring around the liiluni, while the pod of the latter is not con- 

 stricted between the aeeds, is much smaller, and has seeds that are entirely black. The 

 largo brown glands on the under side of the leaves and on the calyx of 7^. minima are ' 

 most noticeable.
