Chrysophyllum cainito is a tropical tree of the family Sapotaceae. It is native to the Isthmus of Panama , where it was domesticated. It has spread to the Greater Antilles and the West Indies and is now grown throughout the tropics, including Southeast Asia. It grows rapidly and reaches 20 meters in height. The fruit has numerous names. The common names cainito and caimito likely come from the Mayan words cab (juice), im (breast), and vitis (sap), via Spanish. It is also called variously tar apple, star apple, purple star apple, golden leaf tree, abiaba, pomme de lait, estrella, milk fruit and aguay. The fruit is globose and typically measures from 2 to 3 inches in diameter. When ripe, it usually has purple skin with a faint green area appearing around the calyx. A radiating star pattern is visible in the pulp. Greenish-white and yellow-fruited cultivars are sometimes available. The skin is rich in latex, and both it and the rind are not edible. The flattened seeds are light brown and hard. It is a seasonal fruit bearing tree. (Source: Wikipedia.org, CC BY-SA)
