Buds and young branchlets glabrous. Terminal buds elongate,' at- 
tenuate, curved. Leaves much smaller than those of D. trinervis, oval, 
acute, base subeuneate, 11 to 18 cm long, 6 to 10 cm wide; secondary 
nerves 10 to 14 pairs; petiole one-third to one-fourth the length of the 
blade. Fruit 1 to 2 cm in diameter, the calyx-tube much constricted at 
the top. 
This species presents an appearance extraordinarily like that of D. 
vernicijluus ; from which it differs in its more glabrous leaves and in its 
elongate, attenuate, curved and glabrous terminal buds.
