I have not seen any specimen, but Spanoghe's character seems to indi- 
cate a Derris allied to D. elegans.

20. D. FERRUGINEA (Benth. in Pl. Jungh. i. p. 252 in adnot.), foliolis 
7-9 obovali-oblongis ellipticisve subacuminatis subtus ad venas elevatas

* Pongamia elongata, n. 5915, is a very doubtful species. With the leaflets 
rather longer than in D. scandens, it has a broad, rather thick pod, with a very 
narrow wing. There are no flowers to the only specimen in the collection.
