faintly reticulate, quite glabrous, shining ; main-nerves 16 to 18 pairs, 

 spreading, little curved, interarching boldly at a little distance from the 

 edges, prominent on the lower surface, depressed on the upper ; midrib 

 very bold on the lower surface, depressed on the upper ; length 7 to 9 

 in., breadth 3 to 3-75 in. ; petiole -4 in., very stout. Male flowers about 

 •5 in. long, salver-shaped, in short axillary cymes, coriaceous, sub- 

 sessile, "5 in. long. Calyx and corolla everywhere adpressed-tomentose. 

 Calyx shorter than the corolla, campanulate, cleft to near the base into 

 5 oblong, blunt, sub-erect lobes. Corolla-tube narrow, not constricted at 

 the throat ; limb with 5 large broad rotund lobes with recurved edges. 

 Stamens 10, united in pairs by the bases of their filaments, the inner 

 ones smaller, all inserted on the base of the calyx- tube. Female flowers 



1 to 5 together, -25 to '3 in. long, with 5 deep ovate-oblong auriculate 

 sub-plicate lobes. Corolla '35 in. long, densely hairy outside, deeply 

 lobed ; staminodes 5 ; ovary 10-celled, rusty-hairy. Fruit sub-globose, 

 sub-truncate at base and apex, glabrous when ripe ; the hispid accrescent

 (1882). A tree 20 to 30 feet high ; young branches half as thick as a 

 goose-quill, pale puberulous, the bark dark. Leaves alternate, coriaceous ; 

 elliptic or elliptic-oblong, sub-acute or obtuse, the base broad or sub- 

 acute ; the upper surface dark olivaceous-brown when dry, glabrous 

 except the depressed puberulous midrib, the reticulations minute but 

 distinct ; lower brown, glabrescent but puberulous on the rather stout 

 midrib and nerves ; main-nerves 10 to 12 pairs, rather faint, spreading, 

 horizontal, interarching boldly about "25 in. from the edge ; length 5-5 

 to 7*5 in., breadth 2-5 to 3'25 in. ; petiole -4 to "5 in., stout, pubescent. 

 Male floivers unknown. Female floioers '5 in. long, axillary, solitary or 



2 together, sessile. Calyx coriaceous, densely pubescent inside and 

 out, deeply divided into 5 broadly oblong, sub-acute lobes, accrescent, 

 and becoming concave along the midribs of the lobes. Corolla some- 

 what longer than the calyx, sericeous externally ; the tube short, the 

 limb-lobes deep, broadly oblong, blunt ; staminodes few, flat. Ovary 

 broadly ovoid, densely sericeous-tomentose. Fruit ovoid-ellipsoid, 

 nearly 1 in. long, and slightly less in diam., glabrous ; the accrescent 

 calyx embracing its base deeply 5-lobed, plicate.
