fig. 86-99. A lofty tree up to 80 ft. high, exuding a whitish latex ; 
trunk straight, 1-2 ft. in diam. at the base, bare below up to two- 
thirds of its height, loosely branched above; branches spreading 
horizontally or slightly deflected, long and strong, tortuous ; young 
branchlets dark-purple, glabrous. Leaves elliptic or ovate-elliptic, 
shortly and obtusely pointed at the apex, rounded and oblique at 
the base, usually about 3-8 in. long and 144 in. broad, coriaceous, 
some (probably from young and vigorous shoots) unequally cordate 
at the base, up to 17 in. long and 7} in. broad, and then thinly 
chartaceous, all glabrous, reddish-brown when dry ; lateral nerves 
in the smaller leaves about 6 on each side of the midrib, arcuate, 
looped within the margin, prominent below, in the larger leaves 
up to about 15 on each side of the midrib ; tertiary nerves and veins 
loosely reticulate below; petiole }-} in. long; stipules caducous, 
lanceolate, acute, 4 in. long, submembranous, often minutely 
puberulous outside. Flowers dicecious. Male heads axillary, very 
shortly pedunculate, globose or slightly ellipsoid, 14-2} in. in diam. 
when the anthers are ripe, beset with peltate densely crowded 
puberulous scales between which the anthers emerge. Perianth 
usually 2-fid ; lobes erect, ciliolate, closely embracing the filaments. 
Stamens 2-4, when 2, then often the third inclined to be rudimentary, 
similarly when 3 some of the flowers have 4 stamens and the anther 
of the fourth is often much smaller than the others; filaments 
stout and glabrous; anthers 1-14 lin. long. Fruit a syncarp, 
more or less globose, as large as to twice as large as a man’s head. 
yellowish outside when ripe, very rough with the knob-like tops of 
the perianth-segments; style with two exserted lobes, slender,
