Description and Ethnobotany

Others - Plant Morphology	Growth Form: Medium-sized tree with a dense, rounded crown that becomes spreading and irregular at maturity. Habitat: Found in lowland forests and river banks. Also, occurs in waste areas and along roadsides. Trunk: Short, low-branching trunk has grey, smooth bark. Foliage: Alternate leaves are pinnately compound with up to 24 pairs of oblong leaflets. Flowers: Flowers are arranged in inflorescences known as racemes. Inflorescences are located at branch tips or in leaf axils. Trees begin to flower at 2 - 3 years of age. Fruits: Fruits are long, flattened pods with numerous ellipsoid seeds. Landscaping: This free-flowering tree species has an attractive rounded crown with fine leaf texture. It is often planted as a roadside or ornamental tree. Cultivation: This species is fast-growing and tolerant of infertile soils, drought and flooding. It does not grow well in shallow soils. Propagation: Propagate by seed. Seeds have a maximum storage life of 3 years. Fresh seeds have a high germination rate, whereas stored seeds should be soaked in concentrated sulfuric acid or boiling water for 10 - 30 min to promote germination. Propagation by stem- or root-cuttings does not work well.
