Description

Carica papaya is a fast-growing, soft-wooded, evergreen tree-like herb, usually 2–10 m tall, with a single, hollow, unbranched stem marked by prominent leaf scars. Leaves are large, simple, palmately lobed, 30–70 cm wide, borne on long hollow petioles, and clustered near the stem apex. The species may be male, female, or hermaphroditic.

Fruits are large, fleshy berries, spherical to oblong, green when immature and turning yellow to orange when ripe, containing numerous small black seeds embedded in a gelatinous pulp.
