1. DiALiuM KuNSTLERi Prain. A tree 100-130 feet higli with 

 spreading branches, stem 2-3 feet thick ; branchlets slender, pale, 

 rugose glabrous. Leaves alternate, odd-pinnate, 5-6 in. loug ; leaflets 5, 

 rarely 3, alternate or subopposite, ovate-lanceolate, narrowly acuminate, 

 apex entire, base cuneate, 4-5 in. long, 1 '25-1 '5 in. wide, coriaceous, 

 rather dark-green shining above, dull and pale green beneath, glabrous 

 on both surfaces ; lateral nerves ascending 5-6 pairs hardly visible 

 above faint beneath and with there a very faint reticulate intermediate 

 secondary venation ; petiolules stout, very short, -1 in. long, glabrous. 

 Panicles terminal and axillary 4 in. long, 3 in. wide ; branches 2 in. 

 long, glabrous, pedicels (in fruit) '2 in. long. Calyx and stamens not 

 seen. Pod subspherical, hardly compressed, obliquely prominently 

 umbonate at the tip, firm, I'S in. long, 1-35 in. across ; glabrous, very 

 faintly verrucose, black. Seed solitary subrotund, smooth, dark-brown, 

 dull, -6 in. long, '5 in. wide, '2 in. thick.

This very fine species, easily distinguished from all the others by its much 

 larger pods with very pronounced umbonate apex, has been but once reported and 

 then, unfortunately, without flowers. It is perhaps most nearly related to B. indum 

 from which, however, besides differing as to fruits it is also distinguished by its 

 thicker and fewer leaflets. No native nnme has been given for the species.
