Nephelium hypoleucum
Korlan is an evergreen tree in the rambutan genus, found wild in tropical Southeast Asian forests and not commercially cultivated. Its key to growing is a warm, humid tropical climate and well-drained fertile soil.
Nephelium hypoleucum, the korlan, is an evergreen tree in the family Sapindaceae. It is in the same genus as the rambutan and also closely related to several other tropical fruits including the lychee, longan, and guinep. The plant is native to Southeast Asia and lives wild in the jungles of the region.
Nephelium hypoleucum will only grow in fertile sandy soil at high altitudes of up to 1200 meters (about 3937 ft), This species is mainly found in rainforests as well as savannah in a hilly country. It prefers to be in a tropical climate with high temperatures and high humidity.
The fruit is commonly eaten fresh off the tree. Only the pulp is eaten due to the seed being poisonous and is described to have a sour taste. Unlike the other similar fruits in this family, the korlan is picked by the locals to be sold in small quantities due to it not being cultivated. Nephelium hypoleucum cannot be grown commercially and there is not a lot of information on the growth rate of this tree. The fruit is sometimes peeled and eaten with salt and chili powder, or fish sauce and sugar. Korlan is believed to have medicinal qualities such as reducing stress, regulating blood sugar, helping with digestion, and increasing resistance to the flu, viruses, colds and herpes, although these claims have not been evaluated by medical studies.
