Dipterocarpaceae

a family of dicotyledonous choripetalous plants. There are about 330 species making up 17 genera (16 in tropical Asia and one in tropical Africa). Almost all the representatives of this family are evergreen trees attaining a height of 60-70 m. The leaves are alternate and with stipules; the flowers are regular, bisexual, and gathered into spikes, racemes, or panicles. There are five sepals and five petals, from five to 15 or more stamens, and one pistil with a three-celled ovary. The fruit is a monospermous nut surrounded by a calyx whose sepals become enlarged and help spread the fruit. Economically important are species of the genera Shorea, Dipterocarpus and Drioblanops, which yield valuable timber, dammar, balsam, camphor, and refractory fats.

Large emergents rise high above the main canopy in all the world's main rainforest regions, but different taxa dominate in different places: in southeast Asia large dipterocarp trees are particularly important emergents, but in other regions the emergents mainly belong to other families.
