Tree to 20 m. high; branches light gray, fissured. Leaves crowded at branchlet tips; petioles yellow or yellow-green, pubescent to glabrous, 1.5-5 cm. long; blades pubescent to glabrous, dark green, somewhat shining above, glaucous below, coriaceous, ovate or obovate-oblong, 10-30 cm. long and 3-20 cm. broad, the base cuneate or obtuse, the apex acute or obtuse or obtusely acuminate, the lateral nerves up to 10 pairs, elevated beneath, the venation yellow. Inflorescence of axillary subterminal panicles, densely pubescent, many-flowered, with deciduous bracts. Flowers small (6-7 mm. long, 0.5-1.5 mm. in diameter), fragrant, tomentose, with yellow-green pedicels up to 5 mm. long; perianth yellow-green or light yellow, the lobes unequal, the outer 3 mm. long, the inner 6 mm. long, persistent; stamens of ser. I & II 2.5-3.5 mm. long, those of ser. III longer, with extrorse anthers; staminodia short-stiped; gynaecium 4-5.5 mm. long, the ovary pubescent, the stigma discoid. Fruit large, pear-shaped, globose, or oval, 7-20 X 7-10 cm., the pulp fleshy, thick, juicy, oily, the seed large, 2.5-5 cm in diam-eter, globose.
Tree to 15 (–20) m high. Young growth covered with appressed, whitish hairs. Leaves alternate, simple: lamina elliptic to obovate-oblong, (5–) 10–30 (–40) cm long, (2.5–) 4–10 (–19) cm wide, coriaceous, upper surface glossy dark green and glabrous or with sparse hairs (visible with lens), lower surface glaucous and sparsely hairy; secondary veins prominent, reticulum coarsely areolate; petiole 2–7 cm long.

A small to medium sized tree. It grows 8-10 m high. Trees can grow to 25 m high. The leaf stalk is 1.5-5 cm long. Leaves are entire, oval and 5-40 cm long. Flowers are greenish, small and on the ends of branches. Clusters of flowers may contain 200-300 flowers. Normally only 1-3 fruit develop from each cluster. The fruit is pear shaped or round. It can be 7-20 cm long. The fruit are greenish-yellow with some red coloration. The fruit has greenish yellow flesh and a large round seed. There are 3 named races-West Indian, Guatemalan and Mexican.
