Location: Campus Masjid area, Rauza
Characters: Teak is a large deciduous tree up to 40 m tall with grey to greyish-brown branches, known for its high quality wood. Its leaves are ovate-elliptic to ovate, 15–45 cm long by 8–23 cm wide, and are held on robust petioles which are 2–4 cm long. Leaf margins are entire. The longest teak bridge in the world at 1.2 km. Fragrant white flowers are borne on 25–40 cm long by 30 cm wide panicles from June to August. The corolla tube is 2.5–3 mm long with 2 mm wide obtuse lobes. fruits are globose and 1.2–1.8 cm in diameter. 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. Heartwood is yellowish to golden-brown. It darkens as it ages. There can be a large variation based on which region the Teak is from. Old growth has much tighter rings than new growth. There is a leather-like scent in newly cut wood.
General use: 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 finishings. Although easily worked, it can cause severe blunting on edged tools because of the presence of silica in the wood. Teak is used extensively in India to make doors and window frames, furniture, columns and beams in homes. 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. 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 colour.Teak is used as a food plant by the larvae of moths of the genus Endoclita.
