Large spreading tree, the wood reddish, the branchlets glabrous, with short internodes; 



stipules lance-oblong, about 3.5 cm. long, filiform-attenuate, glabrous; petioles about 2 mm. 



long; leaf-blades obovate or rhombic-obovate, 34-44 cm. long, 13.5-25 cm. wide, narrowed from

glabrous, the costa and lateral veins impressed, paler and reddish beneath, obscurely puberulent 



when young, the venation prominent, the lateral veins slender, about 20 on each side, nearly 



straight, the secondary veins numerous, parallel, distinct, the ultimate veinlets prominulous, 



reticulate, the margin plane; fruit (probably immature) globose, 5.5 cm. in diameter, glabrous,

 within; petioles very thick, 1 cm. long or shorter; leaf-blades obovate, oblong-obovate, rhombic- 

 obovate, or oblong, 14—35 cm. long, 5.5-19 cm. wide, attenuate to an acute base, acute or ob- 

 tusely short-acuminate at the apex, sometimes rounded and apiculate, chartaceous or sub- 

 coriaceous, lustrous above, glabrous, or puberulent along the veins, the venation plane or 

 subimpressed, lustrous and glabrous beneath or dull and densely short-pilose, the lateral veins 

 prominent, 10-13 on each side, subarcuate, the secondary veins irregularly reticulate, the
