Geographic Distribution and Habitat –
Mammea americana is a plant native to the Caribbean, where the tree is also widely cultivated in the tropics and Central America.
This species was then introduced to various regions of the Old World: West Africa, particularly Sierra Leone, Zanzibar, Southeast Asia and Hawaii. In the United States, the species is found only in Hawaii and Florida.
The habitat of this plant is limited to tropical or subtropical climates. In Central America, the species grows up to an altitude of 1,000 m. It thrives best in rich, deep and well-drained soils, but is very adaptable; it also grows on limestone in Jamaica, in the Oolithic limestone of the Bahamas and on ancient coral rocks in Barbados, as well as on coral reefs off the coast of Florida.
Mammea americana is an 18-21 m tall evergreen tree, similar in appearance to Magnolia grandiflora).
The trunk is short and reaches 1.9-2.2 m in diameter.
The erect branches of the tree form an oval head.
It has dark green, rather dense foliage, with opposite, leathery, elliptical leaves. The leaves can reach 10 cm in width and double in length.
The flower is fragrant, has four or six white petals and reaches 2.5–4.0 cm in width when fully blossomed. The flowers are carried singly or in groups of two or three, on short stems. A single flower can have pistils, stamens, or both, so the flowers can be male, female, or hermaphrodite on a tree.
The fruit is a berry, although it is often misinterpreted as a drupe. It is round or slightly irregular, with a brown or gray-brown crust 3 mm thick. In fact, the rind is made up of the exocarp and the mesocarp of the fruit, while the pulp is made up of the endocarp. The stem is thick and short. The fruit has a more or less visible floral residue at the apex.
Its diameter ranges from 10 to 20 cm. When unripe it is hard and heavy, but its pulp softens slightly when fully ripe. Under the skin there is a white, dry membrane, the taste of which is astringent and adheres to the meat. The pulp is orange or yellow, non-fibrous and can have various textures (crunchy or juicy, firm or tender). Generally the smell of the pulp is pleasant and appetizing.
Small fruits contain only one seed, while larger ones can have up to four. The seeds are brown, rough and oval and about 6 cm long. The juice of the seed leaves an indelible stain.
Mammea americana is a plant that can grow to a limited extent in humid to humid tropical or sub-tropical climates. This plant grows best in the lowlands, but can be successful at altitudes of up to 1,000 meters.
It grows best in areas where annual daytime temperatures are between 24 and 30 ° C, but can tolerate 12 – 35 ° C.
In dormant conditions the plant can survive temperatures down to around -2 ° C, but the growth of young seedlings can be severely damaged at 0 ° C.
From the pluviometric point of view, it prefers an average annual rainfall in the range of 1,200 – 1,800 mm, but tolerates 800 – 2,600 mm.
It prefers a location in full sun or light shade and is best suited to deep, rich and well-drained sandy soils, with a pH in the range of 6 – 6.5, tolerating 5.5 – 8.
Trees can produce their first harvest 6 to 10 years after planting.
Good trees can produce 300-400 fruit per year and there are also several varieties.
Propagation can be done by seed. Germination occurs from 60 to 260 days. Grafting is the preferred method of propagation.
Customs and Traditions –
Mammea americana is a widely cultivated tree, especially in courtyards, in the tropics for its edible fruits. With its glossy, dark green leaves and dense foliage, it makes a beautiful ornamental tree and therefore is often planted for shade around homes, parks and along streets.

In the Bahamas the pulp is first put in salted water to remove the bitterness, before cooking it with a lot of sugar to make a kind of jam. The pulp can also be eaten stewed.
The fruit is rich in pectin and therefore good preserves are obtained, these taste remarkably similar to apricot jams.
Unripe green fruit is richer in pectin and can be added to low-pectin fruit when making jellies, jams, etc.
From the fragrant flowers a liqueur is obtained by distillation.
An alcoholic drink is fermented from the sap of the tree.

The plant contains coumarins, in particular mamaina.
The unripe fruits, as mentioned, are rich in pectin and the bark of the trees is rich in tannin.
Various parts of the tree contain insecticidal substances, especially the seed kernel. In Puerto Rico, mama leaves are wrapped around young tomato plants to keep mole crickets and worms away. Similarly, bark gum is dissolved with fat in Jamaica and Mexico, then applied to the feet to repel fleas or fleas on animals. The same effect is also obtained from infusions of semi-ripe fruits.
In the Virgin Islands, tannin from the bark is used to tan leather. The wood of this plant is heavy and hard, but easy to work; it received, however, only limited commercial interest.
