The rambutan (IPA: [ramˈbu.t̪ɑn], Nephelium lappaceum) is a medium-sized tropical tree in the family Sapindaceae, and the fruit of this tree. It is probably native to 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 where the name quite literally means "hairy." In Panama, Costa Rica, and Nicaragua, it is known as mamón chino.
