isolated specimens, according to a note on the specimen communicated by Capt. Pullen. 
Dr. Schimper’s specimen is from a planted tree, and on its label he queries if it be in- 
troduced. 
Apparently widely spread in Central and Southern Asia. 
2. A.amara, Boivin ; Benth. in Hook. Journ. Bot. 1844, 90. Tree

A. affinis was specifically distinguished by M. Fournier on the ground of its longer 
and broader legume, but our specimens do not support its separation.
