Description:
Pond-apple tree is generally semi-decidious.It grows in swamps, is tolerant of saltwater, and cannot grow in dry soil. The trees grow to a height of around 10–12 m. They have thin, gray trunks and sometimes grow in clumps. The leaves are ovate and  alternate.  They are   oblong with an acute tip, 8–15 cm long and 4–6 cm broad.They can be more than 4 in (10 cm) long, and are shiny green on the upper face.The pond apple has flowers with white petals which have a pink base. They are about 1 in (2.5 cm) in diameter. The fruit is oblong to spherical and apple-sized or larger, 7–15 cm long and up to 9 cm diameter, and falls when it is green or ripening yellow. It disperses by floating to new locations, and it is food for many animal species. It is edible for humans, and can be made into jam, although the taste is usually not preferable to Soursop and other related fruits. The flesh is sweet-scented and agreeable in flavor, but it has never attained general popular use.

The pond apple is a rounded fruit that is similar either to a rounded mango, or an apple. This fruit can be up to 4 in (10 cm) long and more, and is yellow-green when ripe. Its flesh is edible and aromatic, even if this fruit is seldom consumed. In fact, this wild fruit is considered to be inferior in quality to its more well-known relatives like cherimoya, atemoya and custard apple. However, the pond apple can be eaten raw, or transformed into juice.


Cultivation:

*Annona glabra requiert les expositions suivantes : lumière,soleil
*This tree can grow in very moist soils.

Experiments in South Florida have been made in an attempt to use it as a superior rootstock for Sugar-apple or Soursop. While the grafts initially appear to be effective a high percentage of them typically fail over time. Soursop on Pond-apple rootstock has a dwarfing effect.

Although tropical, a mature pond apple can withstand brief negative temperatures down to about 28°F/26°F. (-2°C to -3°C) This tree is considered as invasive in many tropical areas.

It is a very troublesome invasive species in Australia. There it grows in estuaries and chokes mangrove swamps, where its seedlings carpet the banks and prevent other species from germinating or thriving.


Constituents:

On a preliminary screening, substantial antimicrobial, antifungal and moderate insecticidal, sporicidal and cytotoxic activities were observed for the hexane extract of the stem bark of Annona glabra L. Chromatographic fractionation of this extract led to the isolation of kaur-16-en-19-oic acid in a large amount as the main constituent, which was found to be largely responsible for the biological activities possessed by the crude extract.

Medicinal Uses:
A recent study suggests that its alcoholic seed extract contains anticancer compounds that could be used pharmaceutically.

Traditional remedy or use: Wood used to make rafts, sharpen blades and bottle corks. Insect repellent and fish poison. Emetic; Used to treat tuberculosis, abdominal cramps, colic, diarrhea, dysentery, jaundice and rheumatism. Tea was used as a vermifuge.

Modern remedy or use: Genus being researched as a treatment for cancer, malaria and H.I.V.
