Abiu is native to the Amazon and is generally about 30 ft high but may reach 100 ft in favorable situations.
The fruit is round, sometimes long-tapering at the base with smooth yellow skin when ripe. The translucent flesh is sweet and fragrant, containing 1 to 4 brown seeds.
Until fully ripe, the fruit is permeated with latex and is gummy and astringent.
