Tectona is a genus of tropical hardwood trees in the mint family, Lamiaceae . [1] [2] [3] The three species are often collectively called teak.
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]
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:
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 is in Uttaradit, Thailand. It is more than 1,500 years old. Its height is 47 metres. [ clarification needed ] [7]
The Indomalayan realm is one of the eight biogeographic realms. It extends across most of South and Southeast Asia and into the southern parts of East Asia.
Teak is a tropical hardwood tree species in the family Lamiaceae. It is a large, deciduous tree that occurs in mixed hardwood forests. Tectona grandis has small, fragrant white flowers arranged in dense clusters (panicles) at the end of the branches. These flowers contain both types of reproductive organs. The large, papery leaves of teak trees are often hairy on the lower surface. Teak wood has a leather-like smell when it is freshly milled and is particularly valued for its durability and water resistance. The wood is used for boat building, exterior construction, veneer, furniture, carving, turnings, and various small projects.
Basilicum is a genus of plants in the family Lamiaceae, first described in 1802. It contains only one known species, Basilicum polystachyon, native to Africa, Madagascar, southern Asia, New Guinea, Australia, and various islands of the Pacific and Indian Oceans.
Holmskioldia is a genus of flowering plants in the mint family, Lamiaceae. It is native to the Himalayas but widely cultivated as an ornamental and naturalized in many places It contains only one known species, Holmskioldia sanguinea, commonly called the Chinese hat plant, cup-and-saucer-plant or mandarin's hat.
Aglaia edulis is a tree species of plant in the family Meliaceae. It occurs in Tropical Asia from India to Yunnan and South-Central China. The wood and timber are used for various purposes.
Anisoptera costata is an endangered species of plant in the family Dipterocarpaceae. The specific epithet costata means "ribbed", referring to the prominent venation of the leaf blade. A huge emergent tree up to 65 m high, it is found in evergreen and semi-evergreen lowland tropical seasonal forests of Indo-Burma and in mixed dipterocarp forests of Malesia.
Gmelina is a genus of plants in the family Lamiaceae. It consists of about 35 species in Australia, New Guinea, New Caledonia, Southeast Asia, India and a few in Africa. Some species such as G. arborea have been planted and/or become naturalised in India, Africa and Australia. It was named by Carl Linnaeus in honour of botanist Johann Georg Gmelin.
Anisoptera is a genus of plants in the family Dipterocarpaceae. It contains ten species distributed from Chittagong in southeast of Bangladesh to New Guinea.
Plantation teak is a tropical hardwood tree from the genus Tectona, endemic to Southeast Asia that is exclusively planted for the purpose of forestry management, for either commercial timber plantations or ecological restoration. Although the genus Tectona is native to the tropical regions of Southeast Asia, primarily Indonesia, Myanmar, India, Bangladesh and Thailand, the cultivation of plantation teak is economically viable in other tropical regions such as Central America.

Euphorbia antiquorum, known as antique spurge and "Euphorbia of the Ancients", is a species of succulent plant in the family Euphorbiaceae.

Kaptai National Park is a national park in Bangladesh situated in Rangamati District. It was established in 1999 and its area is 5,464.78 hectares. Prior to the declaration of the national park, it was known as Sitapahar Reserve. The original Sitapahar Reserve area was 14,448.0 acres. Out of this an area of 100 acres have been dereserved for the establishment of the industrial estate at Kaptai. It is about 57 kilometre from Chittagong city. It comprises with two Ranges namely Kaptai Range and Karnaphuli Range. Kaptai National park is managed under CHT South Forest Division. It is historically important because teak plantations in Bangladesh were started from this area. Its forest type is mixed evergreen forest. In 2009 IPAC project started its activities in this protected area.
Ilex umbellulata is an evergreen tree species related to holly, generally four to fifteen metres in height. It is found in Southeast Asia. This tree is most often found growing in forests.
