“Gurjun-tree,” Chittagong. “Kanyin-ni,’ Burma. Not grega- 
rious, but scattered in mixed forests, generally taller than the 
trees associated with it. Yields large quantities of wood-oil. 
Roxburgh describes the leaves as smooth on both sides, but 
I agree with Dyer and King that petioles, branchlets, and the 
underside of leaves are often pubescent. There is also a certain 
variation in the nervation of the larger wings of the fruiting- 
calyx. The original fruits upon which Gaertner based his 
species have penniveined wings, the two lateral nerves not 
extending much beyond half their length. Dyer (Journ. Bot. 
1874, tab. 143. fig. 13) represents three basal nerves extending 
through the entire length of the wings, with two shorter lateral 
nerves. One of Hamilton’s specimens, preserved in the British 
Museum, is remarkable for its strong pubescence on petioles, 
underside of leaves, and wings of fruiting-ealyx, as well as for the 
three longitudinal nerves of the calyx-wings. Hamilton calls the 
pubescent form D. turbinatus, and the glabrous form D. levis.

Through the entire Eastern Peninsula, but not at present known 
north of 20? N.lat. In places gregarious on laterite and sandy soils 
in Pegu and Martaban, ascending to 3000 feet, taking the place 
of D. tuberculatus at higher elevations. In Cochinchina and 
Cambodia very common and gregarious.
