Description:  "Trees in southern Florida have broad tops, with some aerial roots and few multiple trunks. The twigs are up to 0.7 cm thick, pubescent, with elongated lenticels. The bark is green or light silvery-gray. The terminal buds are plump, prominent, 3.6 cm long, up to 0.8 cm thick at the base, puberulent on the surface and on the margins of stipules, and tawny or reddish brown. The entire, glabrous leaves are alternate, equilateral, oval, up to 25 cm long and 15 cm broad, with a rounded or bluntly acuminate apex and a broad, rounded base. Venation is prominent, the midrib flanked at the base by 2 pairs of veins, 1 pair much larger than the other, forming a conspicuous angle or "V". There are 5 to 9 pairs of laterals. The texture is coriaceous to subcoriaceous. The surface is green and glossy above, but lighter-colored below. The petioles are up to 11.5 cm long and 0.7 cm broad, somewhat flattened, hardly (or indistinctly) channeled above, green or pink, and puberulent. The figs are axillary, sessile, and mostly geminate. They are spherical, up to 1.5 cm in diameter, pubescent at first, becoming smooth and glabrous, commonly scarlet, and almost devoid of exterior markings. The basal bracts are prominent, and yellowish to pink. The umbilicus is fairly prominent, scarcely 0.4 cm across, with the scales almost concealed or sunken in a pore-like depression. The interior is white" (Condit, 1969; pp. 206-207).

Habitat/ecology:  Large tree, shading out plants beneath. Can establish itself as an epiphyte on other trees, strangling them when it gets larger. Also can establish itself on wall, buildings, bridges, etc.

Propagation:  Seed. Pollination is by a species-specific wasp.

Native range:  Asiatic tropics, from the Himalayas in India to Burma and Malaya.
