Description: An Evergreen tree with a narrow, conical outline and spreading branches. When the tree is young, it produces feathery, mid to grey-green, bipinnate leaves with oblong to lanceolate leaflets. As the tree matures it produces larger, lanceolate leaves with a leathery texture (often alongside the bipinnate leaves), and eventually these will be the only leaves produced. Tiny, pale primrose yellow flowers with many prominent stamens are held in globose flowerheads. The flowerheads are held in Racemes and produced along the branches from late winter into mid-spring.

This plant exhibits dimorphism. On juvenile plants, the leaves are mostly bipinnate with feathery, mid-green to grey-green leaflets that are oblong to lanceolate in shape. As the tree matures the leaves become leathery, flat and lanceolate in shape (these leaves are often sparsely produced alongside the juvenile foliage) and the bipinnate leaves are no longer produced. The leaves are Alternately arranged on spreading branches.
