Description and Ethnobotany
| Growth Form | A deciduous tree with a girth of up to 1 m and grows to 35 m tall. It is fast growing. |
|---|---|
| Crown | Tree form, umbrella-shaped with an open crown density. |
| Foliage | Leaves are bipinnate, 30-60cm long, with 16-20 pinnae. Each pinna has 20-40 oval leaflets, each 0.8-2.5cm long and 0.4-1.0cm long. Flowers are a bright yellow and grow in clusters on upright stalks. |
| Flowers | Flowers have orange stamens and, each flower has crinkled petals with a reddish brown mark in the centre. It would be fragrant particularly at night. These flower clusters would then develop into seedpods of about 5-10cm long and 2.5cm broad. Trees will flower after 4 years. Flowers may occur throughout the year for younger trees, however, flowering usually occurs from March-May and a second flush of flowers may occur in September-November. |
| Fruits | Seedpods are flat, thin and winged. In the initial stages seedpods are red, and then gradually turning black. |
| Others - Plant Morphology | It prefers light to medium well-drained alkaline soils although it can also tolerate clay soils. |
| Associated Fauna | Its flowers are pollinated by insects. |
| Cultivation | Peltophorum pterocarpum is propagated by seeds, grafting or branch cuttings.Before the transplantation of seedlings to the field, it is best to be raised in the nursery for one year. Grafts and cuttings can be carried out to obtain a better uniformity for roadside trees. |
| Etymology | Greek peltophorum, bearing a shield, referring to the peltate stigma; Latin pterocarpum, winged-fruited, referring to the species’ fruits |
| Ethnobotanical Uses | [Others]: Peltophorum pterocarpum provides wonderful shade and thus makes a great specimen for large landscapes and wide-open spaces such as large lawns or parks. It is also very suitable to be a street tree, however regular pruning is required. The elegant yellow flowers of Peltophorum pterocarpum makes it an ornamental tree. Peltophorum pterocarpum is used for fodder. The bark can also be used as dyes as it contains tannins, giving a light yellow colour to leather. Tannin is also present in leaves and wood. In Java, the dye is used for batik work. |
