The jackfruit (Artocarpus heterophyllus)[6] is a species of tree in the fig, mulberry, and breadfruit family (Moraceae).[7] The jackfruit is the largest tree fruit, reaching as much as 55 kg (120 pounds) in weight, 90 cm (35 inches) in length, and 50 cm (20 in) in diameter.[7][8] A mature jackfruit tree produces some 200 fruits per year, with older trees bearing up to 500 fruits in a year.[7][9] The jackfruit is a multiple fruit composed of hundreds to thousands of individual flowers, and the fleshy petals of the unripe fruit are eaten.

Custard apple, (genus Annona), genus of about 160 species of small trees or shrubs of the family Annonaceae, native to the New World tropics. Custard apples are of local importance as traditional medicines, and several species are commercially grown for their edible fruits. The fruit of the common custard apple (Annona reticulata), also called sugar apple or bullock’s-heart in the West Indies, is dark brown in colour and marked with depressions giving it a quilted appearance; its pulp is reddish yellow, sweetish, and very soft (hence the common name). Soursop, or guanabana (A. muricata), sweetsop (A. squamosa), and cherimoya (A. cherimola) are widely cultivated worldwide. Alligator apple, or corkwood (A. glabra), a native of South America and West Africa, is valued for its roots, which serve the same purposes as cork; the fruit is not usually eaten fresh but is sometimes used for making jellies.

Algumas pesquisas indicaram o crescente número de consumidores adeptos da graviola, que a consomem deliberadamente acreditando em um "poder curativo" de algumas doenças como o câncer e o Mal de Parkinson. Esse frisson deve-se ao fato de muitos experimentos terem sido realizados in vitro e in vivo em animais cobaias, sem a total comprovação dos efeitos da substância anonacina neles. Em humanos esses experimentos nunca foram realizados, ao menos não oficialmente. Outro uso que alimenta a economia e o comércio é a elaboração de medicamentos utilizados na medicina popular, com ação antifúngica, antimalárica e citostática.

Annonaceae is the Custard Apple family.
It has over 100 genera with over 2,000 species.

Most are evergreen or deciduous trees with some shrubs. Young shoots are often zigzag.
Leaves, on short stalks, are in 2 ranks, with a simple blade that is pinnately veined.

The usually solitary flowers appear to be axillary or leaf opposed but, due to the way the
    shoots grow are probably terminal.
Flowers can also arise from the trunk which is known as cauliflory.
Some species have bracts at the base of the stalk.

The receptacle (the top of the stalk holding the flower parts) may be enlarged, elevated or flat and there is a
    disk (a disc-like structure at the base of the ovary formed from the receptacle or stamens).

The usually pendulous flowers have a thick, fleshy perianth composed of tepals
    (undifferentiated sepals and petals) or with distinct sepals and petals.
The perianth is usually in 3 whorls of 3 but can be 1 or 2 whorls.

There are up to 100 or more short stamens with the outer ones maturing first.
They are typically spirally arranged.
The anthers open via a longitudinal slit or valve that is directed outwards.
There is an anther appendage and sometimes staminodes (infertile stamens).

The superior ovary can have 10 to 100 or more carpels each with 1-10 ovules.
The carpels are usually separate and spirally arranged.
Each has a short, thick style and a papillate stigma.

To prevent self pollination all (or most of) the flowers are in the staminate phase in the morning and
    the pistillate stage later in the day or the next morning.

The fruit is fleshy with quite large seeds.
Several genera produce edible fruit such as Annona and Uvaria.

Probably Annona muricata (also know as soursop or guanabana). Many thanks to gravitywave for helping with identification.
