Hopea
Hopea is a genus of plants in the family Dipterocarpaceae. It contains some 113 species, distributed from Sri Lanka and southern India to the Andaman Islands, Myanmar, southern China, and southward throughout Malesia to New Guinea. They are mainly main and subcanopy trees of lowland rainforest,[1] but some species can become also emergent trees, such as Hopea nutans.
