Description

Leaves are bipinnately compound, silvery pubescent or glabrescent. Flowers are creamy white, fragrant and in pendulous racemes of up to 300 mm in length. The bark is toxic, rich in alkaloids and tannins and used for tanning leather. Pulverised bark is thrown into water to paralyse fish.

Uses

If cut from the heartwood, it produces durable, insect-resistant timber with a moderately fine, wavy grain which is dark brown to reddish brown, and is used for parquet flooring and fine cabinet and furniture work.

Food plant

The foliage is browsed by the larvae of two Saturniidae moths, Rohaniella pygmaea and Imbrasia forda.
