Fruit type  Capsule
Seeds  Seed is a capsule contains many winged seeds
Seed length 
Seed width 
Seed thickness 
Seed weight  26000 (Carlowitz, 1991) to 56400 seeds/kg (Sen Gupta, 1937; Chacko et al., 2002)
Seed dispersal  By wind
Seed Collection  Ripe capsules are collected from the tree by lopping off the branches just before they dehisce (Chacko et al., 2002)
Transportation of seeds  Capsules collected in cotton bags are transported to the processing centre (Chacko et al., 2002)
Seed processing  Capsules are sun dried and when they dehisce the seeds are separated and cleaned by winnowing (Chacko et al., 2002)
Seed storage  Intermediate (CABI, 1998). Seeds are thoroughly dried and stored under cold conditions in airtight containers for three months (Chacko et al., 2002)
Viability period  Seeds retain viability up to three months (Chacko et al., 2002)
Seed emptiness  Moderate (Chacko et al., 2002)
Seed pre treatment  Cold water for soaking for 24 hrs (Chacko et al., 2002)
Germination type  Epigeal (Chacko et al., 2002)
Germination percentage  2 to 50 (Chacko et al., 2002). L. parviflora showed poor germination (4-9%) (Mamta Purohit et al., 1998)
Germination period  15 to 19 days (Kumar and Bhanja, 1992; Chacko et al., 2002)
Nursery technique  Freshly collected seeds are sown in germination trays filled with vermiculite and watered regularly. Seedlings are potted in polythene bags (22.5 x 17.5 cm) filled with potting mixture (Chacko et al., 2002)
Method of propagation  By seeds
Vegetative propagation 
Pests  Very low (Chacko et al., 2002)
Diseases  Very low (Chacko et al., 2002)
Medicinal properties 
Uses  Wood is used for posts, beams and rafters. It is also used for agricultural implements, constrution work etc. (Chacko et al., 2002). The bark yields a fibre of inferior quality and bark and leaves contain tannin (Bose et al., 1998)
Wood properties  Wood very hard, grey or greyish brown, often almost red, darker coloured near the centre, hard. Larger pores and no distinct annual rings. Medullary rays fine, very numerous, inconspicuous. Pores are conspicuously visible on a longitudinal section (Gamble, 1922)
