About
Nephelium ramboutan-ake, the pulasan, is a tropical fruit in the family Sapindaceae. It is closely related to the rambutan and sometimes confused with it. Other related soapberry family fruits include lychee and longan. Usually eaten fresh, it is sweeter than the rambutan and lychee, but very rare outside Southeast Asia.
The name pulasan comes from Malay: pulas 'to twist' (cognate to Visayan pulas 'to take off, remove' and Tagalog pilas 'to rip, tear'). by how the fruit is opened twisting it with both hands, hence pulasan.
Where it grows
The pulasan is native to Malay Peninsula and other parts of tropical Southeast Asia. Wild trees are infrequent in lowland forests around Perak, Malaysia but abundant in the Philippines at low elevations from Luzon to Mindanao. The tree has long been cultivated in the Malay Peninsula and Thailand; is rarely domesticated in the Philippines. Ochse reported that there were extensive plantings in Java only around Bogor and the villages along the railway between Bogor and the capital Jakarta.
