The rambutan is native to Indonesia, Malaysia, The Philippins, Sri Lanka and elsewhere in Southeast Asia, although its precise natural distribution is unknown. It is closely related to several other edible tropical fruits including the Lychee, Longan, and Mamoncillo. It is believed to be native to the Malay Archipelago, from where it spread westwards to Thailand, Burma, Sri Lanka and India; eastwards to Vietnam, the Philippines and Indonesia. The name rambutan is from the Malay word rambutan, which literally means hairy caused by the 'hair' that covers this fruit, and is in general use in malay and Filipino.
There is a second species regularly for sale at Costa Rican markets which is known as "wild" rambutan. It is a little smaller than the usual red variety and is colored yellow. The outer skin is peeled exposing the fleshy fruit inside which is then eaten. It is sweet, sour and slightly grape like and gummy to the taste. In Costa Rican Spanish it is known as mamón chino (translated “Chinese sucker” )due to the likeness of the edible part with Meliococcus bijugatus and its Asian origin.
Rambutan are non-climacteric fruit - that is, they refuse to ripen unless on the tree.
