Remark: Use: Young shoots are eaten as a vegetable. The leaves are further used as a fodder for cattle but should be used only in a mix with other species, also used as an insecticide. The stem produces tannin, and a resin from the stem can produce a gum. All parts of the plant are medicinal, with anti-cancer properties. The pounded bark is used as a fish poison, and seed as a pesticide against rodents. Thon has good soil-binding capacity and ability to rehabilitate degraded soils by nitrogen fixing. A good shade tree or a wind and firebreak.
Active ingredients: Leaves contain a high fibre and lignin content indicating poor indigestibility.
Harvesting: Yield, densities: Access rules: Sustainability: Conservation status: Processing: Quality criteria: Marketing: Market prospects: Propagation: By seed is usually done. Fresh seed does not need any pre-treatment, stored seed should be treated before sowing by soaking seed in boiling water for 5 seconds and soaked in cool water overnight and sown immediately. Alternatively the seed-coat can be nicked with a nail clipper or sharp knife before boiling the seed.
Description: Tree up to 15-30 m tall and 70 cm in DBH. Leaf rachis 10-30 cm long, pinnae 2-5 pairs, 12-120 cm, leaflets 5-11 pairs, opposite, 3-4.5 by 1.2-2.2 cm, ovate. Panicles up to 30 cm long, with 2-5 peduncles in clusters, ca. 1.5-2 cm long, bearing heads of ca. 20 sessile flowers, ca. 7 mm large. Pods, 17 by 2.5 cm, flat, paperlike, brown, with distinct mark over the seeds, dehiscent. Seed, 6-12 in a pod, 7.5 by 4.5 mm, obovate-elliptic, flat.
Distribution & Ecology: Allover SE Asia, except Malay Peninsula. Found in open areas and deciduous, but also in semi-evergreen forests. If an area is not burned, this fast-growing tree will colonize Imperata cylindrica grassland. During the dry season the tree becomes almost leafless for a short time. Grows best on fertile well-drained alluvial loamy or clay soils, but tolerates shallow soils and acidity.
