7.Botanical name: Albizia
lebbeck Benth
Family:
Mimosaceae
Common name:
Lebbek
Vernicular
name: শিৰিষ /স্বৰ্ণচূড়া
Description: Lebbek is a deciduous, perennial medium-sized legume
tree. It reaches 3-15 m in plantations and up to 30 m in the open. Its dense
shade-producing crown can be as large as 30 m in diameter. Leaves are bipinnate
with 3-11 pairs of bright green, oblong leaflets, 1.5-6.5 cm long x 0.5-3.5 cm
broad. Inflorescences are globular clusters of 15-40 white fragrant flowers.
The fruits are 10-30 cm long x 3-6 cm broad, reddish-brown pods that contain
5-15 flat rounded, free moving seeds. They produce an incessant rattle in the
wind, reminding women's chatter, hence the name "women's tongue" (FAO, 2010; Orwa et al., 2009; Lowry et al., 1992).
Distribution
Lebbek is
native to tropical Africa, Asia and Northern Australia. It is widely
naturalized within sub-humid, semi-arid tropics and subtropical areas where
there is a marked dry season and a reliable rainy season. It is found from sea
level up to an altitude of 1800 m (Cook et al., 2005; Lowry et al., 1992; Duke, 1983).
Optimal growth
conditions are average day temperatures ranging from 19°C to 35°C, annual
rainfall between 500 mm and 2500 mm and fertile, well-drained loamy soils. It
may, however, withstand lower and more irregular rainfall conditions. It can
also grow on a wide diversity of soils such as acid, alkaline or saline soils,
eroded soils and laterites except heavy clays (Orwa et al., 2009; Lowry et al., 1992). It is tolerant of heavy grazing and
fire (Lowry et al., 1992). Seedlings are sensitive to frost and
heavy browsing but older plants can survive (NAS, 1980).
Uses: Good for fire
wood. It is generally planted as shade tree in tea and coffee garden (Orwa et al., 2009; Duke, 1983)..
Its provide shelter for birds and varieties of inspect. Due to rapid growing
nature of the plant, people prefer to plant it in public places for shade. Lebbek is a multipurpose tree. As a fodder tree, its
foliage, twigs, flowers and immature pods are relished by different classes of
livestock (camels, cattle, small ruminants and rabbits) (FAO, 2010). It is also
used planted as timber yielding plant. Lebbek is suitable for agroforestry
regimes in which the benefits of animal production are combined with wood
production (Lowry et al., 1998).
