Hazel Sterculia The Hazel Sterculia is a large deciduous tree that can reach heights of up to 40 m. Distributed from India, Sri Lanka, Bangladesh to Southeast Asia, it grows in coastal areas and semi-open forests and has a straight trunk with a smooth grey to whitish outer bark and fibrous inner bark. The Hazel Sterculia is dioecious, meaning that the male and female flowers are borne on separate trees. Its flowers lack petals, although they have a red, five-lobed calyx that resembles a set of petals. The flowers have an unpleasant smell. In fact, its scientific name hints at the flower’s pungent aroma – its genus, Sterculia, is named after the Roman god Sterculius or Sterquilinus, the god of manure, and its species epithet, foetida, means ‘foul-smelling’.
