The inflorescences appear in the dry season between January and March in axillary or terminal clusters and are both male and female.
The former develop in clusters of 4-20 units, they are usually red, but some varieties have yellow ones.
Each male flower is about a little over a couple of centimeters large and has 4 petals, with anthers attached to a pistil with only one non-functional stigma. The female flowers occur singly or in groups of maximum 4. They are smaller (4-6 mm), their stigmatic surface is normally enlarged.
Flowers with pistils have rudimentary and non-functional stems. Neither male nor female flowers produce nectar. They are pollinated by the wind or by insects.
The fruit is a green, ovoid berry that turns yellow or red when fully ripe, about 5 cm in diameter. The epicarp is marked by 6-10 furrows that make it look like a small pumpkin.
The fruit contains 4-8 smooth, large ovoid seeds surrounded by a succulent and very sour shell (aril) that makes up the fruit pulp.

Cultivation –
The plant is harvested in the wild for its edible fruit and gum-resin, which has medicinal and various other uses.
The tree is also grown outside its native range, especially in China, Malaysia and the Philippines.
It is a plant typical of hot, humid and tropical climates and grows best in areas where the average annual temperature is between 15 and 30 ° C and the average annual rainfall is 1,500 – 4,000 mm.
This plant grows well on both dry and occasionally flooded soils.
The seed plants start producing after 10-12 years while the grafts, carried out from the third year onwards, will reach the stage of full production at the age of 12-15 years.
Ripe fruits, when they are yellow-orange, fall from the tree or are harvested manually. In India, the fruits ripen between June and July, but in certain areas the fruiting can arrive early as early as April.
The rind is separated for processing immediately after harvesting.
The propagation of this plant can take place by seed that must be sown as soon as it is ripe, although the vitality can be maintained for 1 – 2 months in humid storage at 20 ° C.
