The pods of the Burmese species (=Z>. rufa and multijuga, Grah.) differ 

 a good deal from those figured by Roxburgh, and they are much narrower. 

 The pods of the Assam plant are unknown to me, but Mr. Simons calls 

 it " a large tree 30 to 40 feet high." The matter requires further inquiry.

1. D. spnsrosus, (Dalbergia spinosa, Roxb. Fl. Ind. III. 233 ; Hf. 

 Ind. FL II. 238) 



Hab. Frequent in the tidal forests along the coasts from Chittagong 

 down to Tenasserim. — Fl. May, June ; Fr. OS. 



This and the following are referred by Bentham to Dalbergia, but the 

 pods are not winged and the cell-cavity extends from suture to suture. 

 Strictly speaking the pods of Dalbergia cannot be called winged, for 

 the broad thin margins of the pod are simply consolidated so as to leave 

 (as in Dterocarpus) only a central cavity for the seed. 



2. D. monospebmijs, (Dalbergia monosperma, Dalz. in Kew. Journ. 

 Bot. II. 36 ; Miq. Fl. Ind. Bat. I. 132. t. 3. f. D. ; Hf. Ind. Fl. II. 237). 



Hab. Tidal forests of Upper Tenasserim (Falconer). — FL March.
