White Meranti
White Meranti (Shorea cochinchinensis)

Family: Dipterocarpaceae

Common names: Lun, Lun puteh, Melapi, White Meranti

Distributed in: Cambodia (Oceania and S.E. Asia)

Distribution overview: The geographical range of the White meranti group of Shorea spp. includes India in the north and west through the Malayan Peninsula to the Philippines and the Celebes in the east.

Common uses: Beams, Boat building, Building construction, Cabin construction, Canoes, Concrete formwork, Construction, Decks, Decorative plywood, Decorative veneer, Domestic flooring, Excelsior, Factory construction, Figured veneer, Flooring, Form work, Foundation posts, Framing, Heavy construction, Joinery, Joists, Lifeboats, Light construction, Parquet flooring, Plywood, Porch columns, Rough construction, Shipbuilding, Sub-flooring, Veneer

Product sources: Shorea spp. is a major timber source in international trade. The species are abundant, and supplies are plentiful, especially in the form of veneers. This popular wood is priced in the inexpensive range. Many species in the Shorea genera are also a source of other economically important non-timber products. Seeds of some species yield fat which is used in the manufacture of chocolate. Others produce nuts, the most common of which is the illipe nuts of commerce produced by S. gysbertisiana . The nuts yield a fat which is similar to cocoa-butter in some of its properties. Shorea trees are also tapped for oleo-resin, and typical dammar is obtained from S. wiesneri which grows in Java and Sumatra. The tree of S. robusta produces dammar which is used as a disinfectant and as incense in religious ceremonies in India. Other non-timber products from Shorea are reported to include tannin and fibers.
