Highly variable. May be a shrub to around 2 metres in height or a tree to 12 m. Leaves are typically oblong shaped and may have serrated margins (though this is mostly found in juvenile plants). The upper surface is dark green, while the lower surface is white and hairy. The cylindrical, pale yellow inflorescences may reach 10 centimetres in length. Seed is contained in ‘follicles’ which form along this inflorescence. These typically open within 12 months and discharge winged seeds.
