Clausena lansium, also known as wampee (Clausena wampi),[1] is a species of strongly scented evergreen trees 3–8 m tall, in the family Rutaceae, native to southeast Asia.
Its leaves are smooth and dark green. White flowers in late March are white, with four or five petals, about 3–4 mm in diameter. The fruit is oval, about 3 cm long and 2 cm in diameter, and contains two to five seeds that occupy ~40-50% of the fruit volume. The tree reaches a maximum height of 20 meters. It grows well in tropical or subtropical conditions, and is susceptible to cold. Wampee trees grow well in a wide range of soil, but will grow best in rich loam.[2]
The wampee is cultivated for its fruit, which looks like a grape. The tree is popular in China, Vietnam, the Philippines, Malaysia, and Indonesia. Less frequently, it is grown in India, Sri Lanka, and Queensland; occasionally, it is cultivated even in Florida and Hawaii.[3]

This small tree was photographed in my native place in Karanprayag, Chamoli (Uttarakhand). It is a planted species here. Fruits are sour and eaten.
Based on Flora of India vol-4 by BSI it appears as Clausena lansium (Lour.) Skeels.
