It has fragrant white flowers alone or in whorls of 6 units about 5 cm wide, 5 petals and 20-25 yellow stamens. The small fragrant hermaphrodite flowers, white or purple, produce nectar for insect pollination.

The fruit, which can be round or oval, is 6.5 to 9.5 cm wide, and its color varies from orange to yellow according to its maturity. Anatomically, the fruit consists of two distinct regions: the pericarp, also called the skin, skin or skin; and the endocarp, or pulp and juice bags.

The skin consists of a waxy epidermis with numerous small aromatic oil glands that give it a particular scent. The amount of wax depends on variety, weather conditions and growth rate.
