Sugar-Apple or sweetsop is the fruit of Annona squamosa, the most widely grown species of Annona and a native of the tropical Americas and West Indies. The Spanish traders of Manila galleons brought it to Asia where its old Mexican name ate may still be found in Bengali ata, Nepalese aati, Sinhalese katu atha, Burmese awzar thee, and atis in the Philippines. It is also known as custard apple in India and (mainly Annona reticulata) in the Philippines. The name is also used in Portuguese as ata.
