The Tembusu (Fagraea fragrans) is a large evergreen tree in the family Gentianaceae. It is native to Southeast Asia. Its trunk is dark brown, with deeply fissured bark, looking somewhat like a bittergourd. It grows in an irregular shape from 10 to 25m high. Its leaves are light green and oval in shape. Its yellowish flowers have a distinct fragrance and the fruits of the tree are bitter tasting red berries, which are eaten by birds and fruit bats. Source: Tembusu, Wikipedia
