Tectona is a genus of tropical hardwood trees in the mint family, Lamiaceae.[1][2][3] The three species, often collectively called teak, are native to south and southeast Asia, mainly India, Pakistan, Bangladesh, Burma, Indonesia and Thailand, and are commonly found as a component of monsoon forest vegetation. They are large trees, growing to 30–40 m (90–120 ft.) tall, deciduous in the dry season. Tectona grandis is an economically important species which is the source of most commercial teak wood products.


Teak belongs to the family Lamiaceae (in older classifications in Verbenaceae). Sometimes it is included in the subfamily Prostantheroideae.[4] There are three species of Tectona:

The genus Tectona is a conserved name against the earlier homotypic synonym Theka Adans.[2] The genus was originally described by Carl Linnaeus the Younger in 1782.[5]
