Botanical description of mango:

The habit of growth: The mango trees make attractive landscape specimens and shade trees. They are erect and quickly developing with adequate warmth, and the canopy can be wide and rounded, or more upright, with a generally slender crown.
Tree: Generally, the mango tree is evergreen with a symmetrical, rounded canopy that ranges from low and dense to upright and open. It is medium to large 10 to 40 m in height.
Foliage: In general, mango leaves are dark green above and pale underneath. The leaves are substitute, without any stipules, simple, leathery, elongated-lanceolate to linear.
Root: The tree establishes a long unbranched long taproot (up to 6 to 8 meters and more) in addition to a dense mass of superficial feeder roots.
Flowers: Mature terminal branches bear pyramidal flower panicles that have a few hundred white flowers that are about 0.6 cm wide when open. A large portion of flowers work as males providing pollen, however, some are bisexual and set fruit. Pollination is done by flies, wasps, and bees.
Inflorescence: It is a branched panicle borne at shoot terminals, 6.4 to 40.6 cm, having numerous tiny (4 mm) greenish-white or pinkish flowers. 
Fruits:  The mango fruit is a sporadically egg-shaped and somewhat compacted enormous fleshy drupe. It differs in size, shape, color, presence of fiber, flavor, taste, and a few different characters relying upon the variety.

Note: Each mango has a single compressed-ovoid seed encased in a stony endocarp, varying in size/shape with two fleshy cotyledons. Basically, the seed is large, flattened, the kidney-shaped central stone contains one or more large, starchy embryos, producing several seedlings that are identical but not always true to the parent type and can constitute up to 20% of fruit weight.
