mafai cheen (Thai), wampi/wampoi (Malay), wampi/huampi (Philippines)
(Clausena lansium — Family Rutaceae)
The wampee is from a Chinese fruit tree which is also cultivated in Southeast Asia and in the West Indies. It is a very distant relative of the citrus fruits and resembles miniature limes.
Growing in clusters, this small yellow-green fruit contains an aromatic, mildly acid pulp which is pleasant to eat raw or as a jam.
Other trees of the same genus have medicinal, rather than edible, properties.
Clausenia excavata has some interesting Malay names: pokok kemantu (ghostly tree) and pokok cerek (diarrhea tree ).
