Flora of the Malayan Peninsula. 
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 -1 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. Gorolla-tiobe 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 
calyx '75 in. across, its lobes auriculate ; albumen of seed not

(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 flowers unknown. Female flowers - 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 diarn., glabrous ; the accrescent 
calyx embracing its base deeply 5-lobed, plicate.
