Description and Ethnobotany

Growth Form It is a tree, up to 12 m tall, with spreading dome-shaped crown and drooping branches. It may be deciduous in the monsoonal regions.
Foliage Leaves are odd-pinnate (imparipinnate) and in alternate arrangement. Leaflets are glossy and broadly ovate to elliptic shaped.
Flowers Flowers occurs in a branched cluster (panicle) or a raceme. The flowers are bright yellow, pea-shaped and reportedly fragrant. Flowering is seldom observed in Singapore.
Fruit Fruits have yet to be observed in Singapore.
Similar It is smaller in stature and more pendulous than Pterocarpus indicus
Associated Fauna It is prone to being attacked by leaf-mining caterpillars of a moth (Neolithocolletis pentadesma).
Cultivation Low-branching and pendulous branches can often reach the ground. Prune the branches periodically for pedestrian access or vehicular clearance when needed. It thrives in moist sandy loam or clay loam soil, and can tolerate compacted clayey soils found in urban sites. Like Pterocarpus indicus , it is prone to being attacked by leaf-mining caterpillars of a moth (Neolithocolletis pentadesma). During severe infestation, the leaves may become unsightly and even completely defoliated. The use of systemic soil drench or trunk-injection pesticides may help to control the caterpillar infestation. The tree may also be susceptible to fusarium wilt, caused by the Fusarium oxysporum fungus.
Etymology The genus ‘Pterocarpus’, in Greek, means winged seed. The species epithet 'indicus' refers to India, one of the places where it occurs naturally.
Ethnobotanical Uses Others: The bark may produce red sap when cut.
