Rambutan. The rambutan, nephelium lappaceum, is a close relative of the lychee. It distinguishes itself from the lychee by its soft, red hairy rind.
Rambutan is called the hairy lychee and it derives its name from the Malaysian word for hair, "rambut."
The Rambutan grows in clusters on large trees native to tropical Malaysia. Its flesh tends to be white and contains one seed. It is juicy and sweet like the lychee, but less acidic in flavor.
