Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Intsia palembanica or commonly known as Borneo Teak is a tree growing up to 50 m tall with trunk diameter of up to 120 cm. It can be found in forests in East Asia. Young seeds are edible. The bark and wood yields brown and yellow dyes used for coloring mats and clothes. The wood is heavy, hard, strong, durable and resistant to fungi, wood borers, and termites. It is used for high-grade construction work, interior finishing, panelling, parquet flooring, furniture, etc.

Bark and leaves are used medicinally[310].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

Other Uses: Brown and yellow dyes are obtained from the bark and wood[46 , 310 ]. They are used for colouring mats and clothes[46 ]. The heartwood is orangey-brown, becoming dark red-brown or dark brown when exposed to the light; it is clearly demarcated from the 5 - 8cm wide band of white or pale yellow sapwood. The texture is coarse but even; the grain interlocked or wavy. The wood is heavy; hard to very hard; strong; durable, being resistant to fungi and dry wood borers, and moderately resistant to termites and ocean water. It seasons slowly, with only a slight risk of checking and distortion; once dry it is stable in service. The wood works well but has a fairly high blunting effect, stellite-tipped and tungsten carbide tools are recommended; nailing and screwing are good, but require pre-boring; gluing is correct; the wood takes a very fine polish. It is used for high-grade construction work, interior finishing, panelling, parquet flooring, furniture, railroad ties and beams[46 , 661 , 848 ].

Cultivation details

A tree of the moister lowland tropics, it is found most commonly near sea level, though it can succeed at elevations up to 450 metres[303 ]. It grows best in areas where the minimum temperature does not fall below 17?c and the maximum is no higher than 33°c[303 ]. It is susceptible to frost[303 ]. It tolerates an annual rainfall in the range 1,500 - 2,300 mm[303 ]. The following notes are taken from Intsia bijuga, and are likely to be more or less true for this species. Prefers a position in full sun[307 ]. Prefers a very well-drained soil[307 ]. Plants are very tolerant of saline soils and salt-laden winds[303 , 307 ]. Established plants are moderately drought tolerant[303 ].
