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.

"Also, chemical analysis revealed that the sap that formed the amber came from Dipterocarpaceae trees, which are common in tropical forests of Southeast Asia," says Grimaldi.
The amber provides the oldest evidence of tropical forests in Asia, tests having linked it to hardwood trees belonging to the Dipterocarpaceae family, which today make up 80 per cent of the forest canopy in Southeast Asia.
In Indonesia in 1989 it was found that Dipterocarpaceae form ectomycorrhizae with mycorrhizal fungi, among which Scleroderma columnare enhanced the seedling growth efficiently in nurseries and that a small amount of charcoal (2% in volume) stimulated the growth of Shorea species and mycorrhiza formation (Ogawa 2006).

Botanical family of Sal is Dipterocarpaceae. The kernel of its nut contains about 15-18% oil, which is removed and used locally in food or sold to the worldwide confectionery industry.
