The pulasan, Nephelium mutabile Blume (family Sapindaceae), is a tropical fruit closely allied to the rambutan and sometimes confused with it.It has various common names, including pulasan in English, Spanish and Malay, kapulasan in Indonesia, ngoh-khonsan in Thailand, and bulala or panungayan in the Philippines.The fruit is ovoid, 5-7.5 cm long, dark red, with its thick, leathery rind closely set with conical, blunt-tipped tubercles or thick, fleshy, straight spines, which are up to 1 cm long.

Within is the glistening, white or yellowish-white flesh (aril) to 1 cm thick, more or less clinging to the thin, grayish-brown seedcoat (testa) which separates from the seed.The flavour is generally much sweeter than that of the rambutan.Filosan Friut plants in keralais now available in our farms.
