Hopea is a genus of plants in the family Dipterocarpaceae. The genus was named after John Hope, 1725-1786, the first Regius Keeper of the Royal Botanic Garden, Edinburgh. It contains about 104 species, distributed from Sri Lanka and southern India to southern China, and southward throughout Malesia to New Guinea. They are mainly main and subcanopy trees of lowland rainforest, but some species can become also emergent trees, such as Hopea nutans.
