Evergreen trees, like the warm tropical temperatures (average temperature 25 degrees Celsius), can reach 8m tall but usually tajuknya widened to 4m radius. Leaves pinnate compound leaves with five to nine children, an oval, with variations depending on age, position in the tree, and local races.
Rambutan growth is influenced by water availability. After a period of fruiting is complete, rambutan trees will blossom (flushing) to produce new branches and leaves. This stage is very clearly observed with a light green color of the tree because it is dominated by the young leaves. This growth will stop when water availability is limited and the rest to grow plants.
Flowering and flower

Rambutan flowering season or affected by water availability. Dry period of three months to stop vegetative growth and stimulate flower formation. In the area of northern Sumatra, who knew no rambutan dry season can produce fruit twice a year. In other places, flowers appear usually after a dry period of three months (in Java and Kalimantan, usually in October and November).
Compound interest, arranged in a bouquet, with flowers the size of the unit 5mm in diameter or even smaller. Male flowers do not produce buds. New pansy flowering plants normally produce male flowers, then followed with interest by means of the female (pistil). Pansy flowers (hermaphrodite) have functional stamens and the ovary has two, although if fertilization occurs only one who usually grow up to mature, while others were reduced. Pollination carried out by different types of bees, but most often present is Trigona, small bees without stings the size of a fly.
