Rambutan, a native of Southeast Asia, now grows in tropical climates all over the world. The leaves differ from one variety to another, but the hairy or spiky red (when mature) fruits are unmistakable. Rambut is the Malay word for "hair". Try one next time you're in the tropics! In Costa Rica they are known as "Mamon Chino" or Chinese Sucker for the way the fruit is eaten and that they are like a lychee fruit from Vietnam.
