Lebbek (Albizia lebbeck)

Family: Leguminosae

Common names: Acacia, Acacia amarilla, Algarrobo de olor, Amor platonico, Aroma, Barba de Caballero, Bengha, Beymada, Black ebony, Cabello de venus, Chichola, Chinchula, Darshana, Dirasana, Dormilon, East Indian walnut, Frywood, Gachoda, Garso, Gokiru, Harreri, Hirih, Indian albizzia, Kal baghi, Kat vage, Kat vaghe, Kinhi, Kokko, Langil, Lebbeck, Lebbek, Lega, Mai-kokko, Mara, Pedda duchirram, Pruek, Samkesar, Sirai, Sirin, Siris, Siris tree, Sirisha, Sirsul, Tama-kai, Tibet, Tinia, Vaga, Vagei, Vaghe, Weru, West Indies ebony, Woman's tongue, Womans tongue tree, Womens tongue, Ye-ho-shu

Asia)

Distribution overview: Indigenous to South-East Asia and Australia (including several regions in India, Bangladesh, the lower hill forests in Burma, and dry regions in Sri Lanka). It has been widely cultivated and is now pantropical. It grows well in areas with 600-2500 mm rain/year but tolerates as little as 300 mm. The altitudinal range is 0-1800 m and mean annual temperature 20-35￿C. Grows well on fertile, well-drained loamy soils but poorly on heavy clays. It tolerates acidity, alkalinity, heavy and eroded soils, and waterlogged soils. It is nitrogen-fixing, tolerant to drought and older trees can survive grass fires and intense night frost. While fire and frost will kill off aboveground growth of young trees, new growth will normally follow. A. lebbeck is also an introduced species elsewhere in the tropics, and can be found growing wild in Nigeria.
