Unfortunately, the wood of plantation teak is considered inferior to that of wild teak; consequently the wild populations are being decimated. Teakwood is moderately hard, easily worked, and extremely durable; beams said to be over 1,000 years old are still functional. The wood contains an essential oil that resists the action of water and prevents the rusting of iron. The heartwood is resistant to termites. Teak is superior to all other woods for shipbuilding and is also used for furniture, flooring, and general construction. Several other similar woods from unrelated trees are sometimes also called teak. Teak (Tectona grandis) is classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).

(Tectona grandis), a tree of the family Verbenaceae. Teak grows to 40–50 m in height and has large leaves 30–60 cm in length. The small flowers grow in panicles. The fruits are drupelike. Teak grows in deciduous forests of Asia, from India to Indonesia. It is cultivated in tropical regions of Asia for its valuable wood, which is used in the construction of ships, trains, and buildings and in furniture-making.
Teakwood is beautiful and has a narrow white alburnum and a yellowish heartwood that browns as it dries. The wood is very tough and resistant to decay, harmful insects, and chemicals, yet it is easily worked. Oldfieldia africana, a tree of the family Euphorbiaceae that grows in West Africa and yields valuable wood, is called African teak.
