In some regions of the world, custard-apple is another name for sugar-apple, a different plant in the same genus.
The Custard-apple (Annona reticulata), known in English as bullock's heart or bull's heart, and in Hindi as sitaphal or Sita's fruit, is a species of Annona, native to the tropical New World, preferring a low elevation, and a warm, humid climate. It also occurs as feral populations in many parts of the world including India, Australia and Africa. It is a small deciduous or semi-evergreen tree reaching 10 m tall. The leaves are alternate, simple, oblong-lanceolate, 10-15 cm long and 5-10 cm broad. The flowers are produced in clusters, each flower 2-3 cm across, with six yellow-green petals.
The fruit is variable in shape, ranging from a symmetrical globose to heart shaped, oblong or irregular. The size ranges from 7-12 cm. When ripe, the fruit is brown or yellowish, with red highlights and a varying degree of reticulation, depending on variety. The flavor is sweet and pleasant, but inferior to that of the cherimoya or sugar-apple. The latter fruit is sometimes confused with this species.
Fatty-acid methyl ester of the seed oil meets all of the major biodiesel requirements in the USA (ASTM D 6751-02, ASTM PS 121-99), Germany (DIN V 51606) and European Union (EN 14214).
A similar fruit, the sugar-apple (Annona squamosa), is also called the sweetsop or, in Vietnamese, mãng cầu.
In Britain Custard-apple refers to cherimoya (Annona cherimola).
