Abiu is an evergreen tree with a dense crown that grows to a height of 6 to 24 meters; in favorable conditions, as high as 35 meters. Leaves are elliptic to oblong, varying in size from 10 to 20 centimeters in length, 3.5 to 65 centimeters in width. Fruits vary in shape, from spherical to oval; vivid yellow when ripe, containing one to four ovate seeds. Seeds are covered by a thin layer of pulp. Flesh of the fruit is transluscent, with a creamy or custard-like texture, with a flavor hinting of rambutan. Not fully ripe fruits yield a latex that stick to lips. Flowers are hermaphroditic, arising singly or in clusters from leaf axils, borne by slender, elongated shoots. Petals are small, four to five, cylindrical, white to greenish in color. Flowers blossom in the morning and staying open for about two days.

• Radical Scavenging Activity / Leaves: Study evaluated various extracts of leaves of Pouteria caimito for radical scavenging activity. The aqueous extract showed the highest total phenol and proanthocyanidin contents (173.6 µg/mL) and highest radical scavenging activity (ED50=38.1 µg/mL. A hexane extract yielded spinasterol. There was a high correlation between total phenolic and proantocyanidin content and radical scavenging activity. (1)
• α-Amylase and α-Glucosidase Inhibitory Activity / Antidiabetic Potential: In a study of several Brazilian plant cerrado species. Pouteria caimito was one of five plant extracts that showed strong α-amylase (IC50=13.6 µg/mL) and α-glucosidase in (IC50=2.50 µg/mL) inhibitory activity.
