Teak

Teak (Tectona grandis) is a tropical hardwood tree species placed in the flowering plant family Lamiaceae. Some forms of teak are known as Burmese teak, Central Province teak (CP teak), as well as Nagpur teak. T. grandis is a large, deciduous tree that occurs in mixed hardwood forests. It has small, fragrant white flowers arranged in dense clusters (panicles) at the end of the branches. These flowers contain both types of reproductive organs (perfect flowers). 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 other small wood projects.[2]

Tectona grandis is native to south and southeast Asia, mainly India, Sri Lanka, Indonesia, Malaysia, Thailand, Myanmar and Bangladesh but is naturalised and cultivated in many countries in Africa and the Caribbean. Myanmar's teak forests account for nearly half of the world's naturally occurring teak.[3] Molecular studies show that there are two centres of genetic origin of teak: one in India and the other in Myanmar and Laos.[4][5]

The English word teak comes from Tamil tekku (தேக்கு), Telugu teku (టేకు), Malayalam thekku (തേക്ക്), Sinhala thekka (තේක්ක), and Kannada tega (ತೇಗ) via the Portuguese teca.[6] In Bangladesh and West Bengal, the species is known as segun (সেগুন). Central Province teak and Nagpur teak are named for those regions of India.[7]

Description

Teak is a large, long, deciduous tree up to 40 m (131 ft) tall with gray to grayish brown branches. These are mostly known for their finest quality wood. Leaves are ovate-elliptic to ovate, 15–45 cm (5.9–17.7 in) long by 8–23 cm (3.1–9.1 in) wide, and are held on robust petioles which are 2–4 cm (0.8–1.6 in) long. Leaf margins are entire.[8]

Fragrant white flowers are borne on 25–40 cm (10–16 in) long by 30 cm (12 in) wide panicles from June to August. The corolla tube is 2.5–3 mm long with 2 mm wide obtuse lobes. Tectona grandis sets fruit from September to December; fruits are globose and 1.2-1.8 cm in diameter.[8] Flowers are weakly protandrous in that the anthers precede the stigma in maturity and pollen is shed within a few hours of the flower opening.[9] The flowers are primarily entomophilous (insect-pollinated), but can occasionally be anemophilous (wind-pollinated).[10] A 1996 study found that in its native range in Thailand, the major pollinator were species in the bee genus Ceratina.[9]

Wood

  • Heartwood is yellowish in colour. It darkens as it ages. Sometimes there are dark patches on it. There is a leather-like scent in newly cut wood.[11]
  • Sapwood is whitish to pale yellowish brown in colour. It can easily separate from heartwood.
  • Wood texture is hard and ring porous.
  • Density varies according to moisture content: at 15% mc it is 660 kg/m3.[12]

Botanical history

Tectona grandis was first formally described by Carl Linnaeus the Younger in his 1782 work Supplementum Plantarum.[13] In 1975, Harold Norman Moldenke published new descriptions of four forms of this species in the journal Phytologia. Moldenke described each form as varying slightly from the type specimen: T. grandis f. canescens is distinguished from the type material by being densely canescent, or covered in hairs, on the underside of the leaf, T. grandis f. pilosula is distinct from the type material in the varying morphology of the leaf veins, T. grandis f. punctata is only hairy on the larger veins on the underside of the leaf, and T. grandis f. tomentella is noted for its dense yellowish tomentose hairs on the lower surface of the leaf.[14]

Distribution and habitat

Tectona grandis is one of three species in the genus Tectona. The other two species, T. hamiltoniana and T. philippinensis, are endemics with relatively small native distributions in Myanmar and the Philippines, respectively.[15] Tectona grandis is native to India, Sri Lanka, Indonesia, Myanmar, northern Thailand, and northwestern Laos.[8][9]

Tectona grandis is found in a variety of habitats and climatic conditions from arid areas with only 500 mm of rain per year to very moist forests with up to 5,000 mm of rain per year. Typically, though, the annual rainfall in areas where teak grows averages 1,250-1,650 mm with a 3-5 month dry season.[16]

Cultivation

Teak's natural oils make it useful in exposed locations, and make the timber termite and pest resistant. Teak is durable even when not treated with oil or varnish. Timber cut from old teak trees was once believed to be more durable and harder than plantation grown teak. Studies have shown that plantation teak performs on par with old-growth teak in erosion rate, dimensional stability, warping, and surface checking, but is more susceptible to color change from UV exposure.[17]

The vast majority of commercially harvested teak is grown on teak plantations found in Indonesia and controlled by Perum Perhutani (a state owned forest enterprise) that manages the country's forests. The primary use of teak harvested in Indonesia is in the production of outdoor teak furniture for export. Nilambur in Kerala, India, is also a major producer of teak of fine quality, holds the world's oldest teak plantation.[18]

Teak consumption raises a number of environmental concerns, such as the disappearance of rare old-growth teak. However, its popularity has led to growth in sustainable plantation teak production throughout the seasonally dry tropics in forestry plantations. The Forest Stewardship Council offers certification of sustainably grown and harvested teak products. Propagation of teak via tissue culture for plantation purposes is commercially viable.[19]

Teak plantations were widely established in Equatorial Africa during the Colonial era. These timber resources, as well as the oil reserves, are at the heart of the current (2014) South Sudanese conflict.[20][21]

Much of the world's teak is exported by Indonesia and Myanmar. There is also a rapidly growing plantation grown market in Central America (Costa Rica) and South America. With a depletion of remaining natural hectares of teak forests, a growth in plantations in Latin America is expected to rise.[22]

Hyblaea puera, commonly known as the teak defoliator, is a moth native to southeast Asia. It is a teak pest whose caterpillar feeds on teak and other species of trees common in the region of southeast Asia.[23]

Uses

Teak's high oil content, high tensile strength and tight grain make it particularly suitable where weather resistance is desired. It is used in the manufacture of outdoor furniture and boat decks. It is also used for cutting boards, indoor flooring, countertops and as a veneer for indoor furnishings. Although easily worked, it can cause severe blunting on edged tools because of the presence of silica in the wood. Over time teak can weather to a silvery-grey finish, especially when exposed to sunlight.[24]

Teak is used extensively in India to make doors and window frames, furniture, and columns and beams in old type houses. It is resistant to termite attacks and damage caused by other insects. Mature teak fetches a very good price. It is grown extensively by forest departments of different states in forest areas.

Leaves of the teak wood tree are used in making Pellakai gatti (jackfruit dumpling), where batter is poured into a teak leaf and is steamed.[25] This type of usage is found in the coastal district of Udupi in the Tulunadu region in South India. The leaves are also used in gudeg, a dish of young jackfruit made in Central Java, Indonesia, and give the dish its dark brown color.

Teak is used as a food plant by the larvae of moths of the genus Endoclita including E. aroura, E. chalybeatus, E. damor, E. gmelina, E. malabaricus, E. sericeus and E. signifer and other Lepidoptera including Turnip Moth.

Boatbuilding

Teak has been used as a boatbuilding material for over 2000 years (it was found in an archaeological dig in Berenice Panchrysos, a port on the Indian Roman trade).[26] In addition to relatively high strength, teak is also highly resistant to rot,[27] fungi and mildew. In addition, teak has a relatively low shrinkage ratio,[28] which makes it excellent for applications where it undergoes periodic changes in moisture. Teak has the unusual properties of being both an excellent structural timber for framing, planking, etc., while at the same time being easily worked, unlike some other similar woods such as purpleheart,[29] and finished to a high degree.[30] For this reason, it is also prized for the trim work on boat interiors. Due to the oily nature of the wood, care must be taken to properly prepare the wood before gluing.[31]

When used on boats, teak is also very flexible in the finishes that may be applied. One option is to use no finish at all, in which case the wood will naturally weather to a pleasing silver-grey.[32] The wood may also be oiled with a finishing agent such as linseed or tung oil.[33] This results in a pleasant, somewhat dull finish. Finally, teak may also be varnished for a deep, lustrous glow.

Teak is also used extensively in boat decks, as it is extremely durable and requires very little maintenance. The teak tends to wear in to the softer 'summer' growth bands first, forming a natural 'non-slip' surface.[32] Any sanding is therefore only damaging. Use of modern cleaning compounds, oils or preservatives will shorten the life of the teak, as it contains natural teak-oil a very small distance below the white surface. Wooden boat experts will only wash the teak with salt water, and re-caulk when needed. This cleans the deck, and prevents it from drying out and the wood shrinking. The salt helps it absorb and retain moisture, and prevents any mildew and algal growth. Over-maintenance, such as cleaning teak with harsh chemicals, can shorten its usable lifespan as decking.[27]

Alternatives to teak

Due to the increasing cost of teak, various alternatives have been employed. These include purpleheart, iroko, and angelique.

Propagation

Teak is propagated mainly from seeds. Germination of the seeds involves pretreatment to remove dormancy arising from the thick pericarp. Pretreatment involves alternate wetting and drying of the seed. The seeds are soaked in water for 12 hours and then spread to dry in the sun for 12 hours. This is repeated for 10–14 days and then the seeds are sown in shallow germination beds of coarse peat covered by sand. The seeds then germinate after 15 to 30 days.[34][35]

Clonal propagation of teak has been successfully done through grafting, rooted stem cuttings and micro propagation. While bud grafting on to seedling root stock has been the method used for establishing clonal seed orchards that enables assemblage of clones of the superior trees to encourage crossing, rooted stem cuttings and micro propagated plants are being increasingly used around the world for raising clonal plantations.[36]

World's largest living teak tree

Ministry of Environmental Conservation and Forestry (Myanmar) found the world's two biggest living teak trees on 28 August 2017 in Homalin Township, Sagaing Region, Myanmar. The biggest one, named Homemalynn 1, is 27.5 feet (8.4 m) in girth and 110 feet (34 m) tall. The second biggest one, named Homemalynn 2, is 27 feet (8.2 m) in girth.[37]

Previously, the world's biggest recorded teak tree was located within the Parambikulam Wildlife Sanctuary in the Palakkad District of Kerala in India, named Kannimara. The tree is approximately 47.5 metres (156 ft) tall.

In 2017, a tree was discovered in the Ottakallan area of Thundathil range of Malayattoor Forest Division in Kerala with a girth of 7.65 metres (25.1 ft) and height of 40 metres (130 ft).[38] A teak tree in Kappayam, Edamalayar, Kerala which used to be considered the biggest, has a diameter of only 7.23 meters.[38]

Teaknet

The International Teak Information Network (Teaknet) supported by the Food and Agriculture Organization (FAO) Regional office for Asia-Pacific, Bangkok, currently has its offices at the Kerala Forest Research Institute, Peechi, Thrissur, Kerala State in India. Teaknet is an international network of institutions and individuals interested in teak. Teaknet addresses the interests of all the categories of stakeholders related to teak, whether they are growers, traders, researchers or other groups with a profound interest or concerned with teak. From time to time, the organisation formulates action plans focusing on the short term and long term needs of the global teak sector. The TEAKNET website[39] provides information to all those concerned with research, conservation, growing, management and utilisation of teak. Grades of teak include First European Quality (FEQ).

Anaimalai Hills

The Anaimalai or Anamala Hills, also known as the Elephant Mountains, are the range of mountains that form the southern portion of the Western Ghats and span the border of Tamil Nadu and Kerala in Southern India. The name animala is derived from the Tamil word anai or ana, meaning elephant, and malai or mala, meaning hill — thus Elephant Hill.

Anamudi Peak (8,842 feet [2,695 metres]) lies at the extreme southwestern end of the range and is the highest peak in southern India. Palakkad Gap divides the Western Ghats to the north. The lower slopes of the hills now have coffee and tea plantations as well as teak forests of great economic value. Dense monsoon forests including rosewood, sandalwood, teak, and sago palms cover most of the region, which helps the coffee and tea plantations and teak plantations grow.

The Western Ghats and Anaimalai Sub-Cluster, including the Anaimalai Hills, are currently under consideration by the UNESCO World Heritage Committee for selection as a World Heritage Site.

Asterids

In the APG IV system (2016) for the classification of flowering plants, the name asterids denotes a clade (a monophyletic group). Common examples include the forget-me-nots, nightshades (including potatoes, eggplants, tomatoes, peppers and tobacco), the common sunflower, petunias, morning glory and sweet potato, coffee, lavender, lilac, olive, jasmine, honeysuckle, ash tree, teak, snapdragon, sesame, psyllium, garden sage, table herbs such as mint, basil, and rosemary, and rainforest trees such as Brazil nut.

Most of the taxa belonging to this clade had been referred to the Asteridae in the Cronquist system (1981) and to the Sympetalae in earlier systems. The name asterids (not necessarily capitalised) resembles the earlier botanical name but is intended to be the name of a clade rather than a formal ranked name, in the sense of the ICBN.

Baikiaea plurijuga

Baikiaea plurijuga, known as African teak, Mukusi, Rhodesian teak, Zambian teak or Zambesi redwood, is a species of Afrotropical tree from the legume family, the Fabaceae from southern Africa.

Butea monosperma

Butea monosperma is a species of Butea native to tropical and sub-tropical parts of the Indian Subcontinent and Southeast Asia,

ranging across India, Bangladesh, Nepal, Sri Lanka, Myanmar, Thailand, Laos, Cambodia, Vietnam, Malaysia, and western Indonesia. Common names include flame-of-the-forest and bastard teak.It is a medium-sized dry-season deciduous tree, growing to 15 m (49 ft) tall. It is a slow-growing tree: young trees have a growth rate of a few feet per year. The leaves are pinnate, with an 8–16 cm (3.1–6.3 in) petiole and three leaflets, each leaflet 10–20 cm (3.9–7.9 in) long. The flowers are 2.5 cm (0.98 in) long, bright orange-red, and produced in racemes up to 15 cm (5.9 in) long. The fruit is a pod 15–20 cm (5.9–7.9 in) long and 4–5 cm (1.6–2.0 in) broad.In West Bengal, it is associated with spring, especially through the poems and songs of Nobel Laureate Rabindranath Tagore, who likened its bright orange flame-like flower to fire. In Santiniketan, where Tagore lived, this flower has become an indispensable part of the celebration of spring. The plant has lent its name to the town of Palashi, famous for the historic Battle of Plassey fought there.In the state of Jharkhand, palash is associated with folk tradition. Many folk literary expressions describe palash as the forest fire. The beauty of dry deciduous forests of Jharkhand reach their height when most trees have shed their leaves and the Palash is in its full bloom. Palash is also the State Flower of Jharkhand.

It is said that the tree is a form of Agni, the God of Fire. In Telangana, these flowers are specially used in the worship of Lord Shiva on occasion of Shivaratri. In Telugu, this tree is called Modugu chettu.

In Kerala, this is called plasu and chamata. Chamata is the vernacular version of Sanskrit word samidha, small piece of wood that is used for agnihotra or the fire ritual. In most of the old namboodiri (Kerala Brahmin) houses, one can find this tree because this is widely used for their fire ritual. Tamil Brahmins have a daily agnihotra ritual called Samidha Dhanan, where barks of this tree is a main component for agnihotra, and this ritual is very essential for brahmacharis during the first year of brahmacharya.

In Theravada Buddhism, Butea monosperma is said to have used as the tree for achieved enlightenment, or Bodhi by Lord Buddha called Medhankara – මේධංකර. The plant is known as කෑල in Sinhala.

Gmelina arborea

Gmelina arborea, (in English beechwood, gmelina, goomar teak, Kashmir tree, Malay beechwood, white teak, yemane ), locally known as gamhar, is a fast-growing deciduous tree, occurring naturally throughout greater part of India at altitudes up to 1,500 meters. It also occurs naturally in Myanmar, Thailand, Laos, Cambodia, Vietnam, and in southern provinces of China, and has been planted extensively in Sierra Leone, Nigeria, Malaysia, and on experimental basis in other countries as well. It is also planted in gardens and avenues.

Hong Kong Dragon Boat Festival in New York

The Hong Kong Dragon Boat Festival in New York is an annual sporting and multicultural event held in August on Meadow Lake in Flushing Meadows–Corona Park in Queens, New York to celebrate the fifth moon (or the fifth month) of the lunar calendar. In addition to providing audiences with traditional Chinese foods and performances, the festival, now in its 18th year, hosts over 150 dragon boat teams from across North America, making it one of the largest dragon boat festivals in the United States. Depending on the competitive division, teams compete for cash prizes or airline tickets.

In 1986, the Hong Kong Tourism Bureau donated traditional teak wood boats to several cities including New York. In 1990, the locally based Hong Kong Economic and Trade Office promoted and organized the inaugural Hong Kong Dragon Boat Festival in New York, which was held on the Hudson River in Battery Park City. Several of the original organizers are still involved with the festival, including Henry Wan, who now serves as the festival's chairman.

The festival is now an independent non-profit company organized under the laws of the State of New York and receives its funding through sponsorships by various companies. The Hong Kong Economic and Trade Office continues to be a substantial supporter of the festival.

In addition to the change in corporate structure, the festival's fleet of dragon boats has grown from 4 teak wood dragon boats to over 30 dragon boats. Many of the boats are made of fiberglass. All the boats are approved by the International Dragon Boat Federation for international dragon boat racing.

Intsia bijuga

This article is about ipil (Intsia bijuga), for the ipil-ipil tree, see Leucaena leucocephala.Intsia bijuga (commonly known as Borneo teak, Johnstone River teak, Moluccan ironwood, Pacific teak and scrub mahogany) is a species of flowering tree in the pea family, Fabaceae, native to the Indo-Pacific. It ranges from Tanzania and Madagascar east through India and Queensland, Australia to the Pacific islands of Fiji and Samoa. It grows to around 50 metres (160 feet) tall with a highly buttressed trunk. It inhabits mangrove forests.

The tree has a variety of common names including ipil, merbau and kwila. In the Philippines, it also known in some areas as taal.

Iroko

Iroko is a large hardwood tree from the west coast of tropical Africa that can live up to 500 years. The tree is known to the Yoruba as ìrókò, logo or loko and is believed to have supernatural properties. Iroko is known to the Igbo people as oji wood. It is one of the woods sometimes referred to as African teak, although it is unrelated to the teak family. The wood colour is initially yellow but darkens to a richer copper brown over time.

It is yielded mostly (probably) by Milicia excelsa. In much of the literature on this timber the names of the trees that yields it are given as Chlorophora excelsa and Chlorophora regia.The tree is feared in some cultures where it originates and hence is shunned or revered with offerings. Yoruba people believe that the tree is inhabited by a spirit, and anybody who sees the Iroko-man face to face becomes insane and speedily dies. According to the Yoruba, any man who cuts down any iroko tree causes devastating misfortune on himself and all of his family, although if they need to cut down the tree they can make a prayer afterwards to protect themselves.They also claim that the spirit of the Iroko can be heard in houses which use iroko wood, as the spirit of the Iroko is trapped in the wood. In Nigeria the iroko wood is of much lower quality due to soil conditions as well as root-rot. Some Westerners refer to the wood as "poor man's teak".

Kerala Forest Research Institute

Hundreds of Empire ships were employed by the Government of the United Kingdom. They were acquired from a number of sources: many were built for the government; others obtained from the United States; still others were captured or seized from enemy powers. Empire ships were mostly used during World War II by the Ministry of War Transport (MoWT), which owned the ships but contracted out their management to various shipping lines; however, some ships requisitioned during the Suez Crisis were also named as Empire ships. Most Empire ships have since been lost or scrapped; however a few still remain in active service or preserved.
