## Description

Tectona is native to south and southeast Asia, mainly India , Pakistan , Bangladesh, Myanmar, 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.[4]

## Systematics

Teak belongs to the family Lamiaceae (in older classifications in Verbenaceae). Sometimes it is included in the subfamily Prostantheroideae.[5] There are three species of Tectona:

* Tectona grandis (common teak) is by far the most important, with a wide distribution in Bangladesh, Sri Lanka, Myanmar, Thailand, China , India , and Pakistan .
* Tectona hamiltoniana (Dahat teak) is a local endemic species confined to Burma, where it is endangered.
* Tectona philippinensis (Philippine teak) is endemic to the Philippines , and is critically endangered according to the IUCN (http://iucnredlist.org/details/32123/0).

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.[6]

## The biggest and oldest teak

The biggest and oldest teak is in Uttaradit, Thailand. It is more than 1,500 years old. Its height is 47 metres.
