Booyongs develop into tall canopy trees with dark coloured scaly bark and pronounced buttressing. Buttresses assist in supporting the trees and their presence is a characteristic of tropical and subtropical rainforests.
The richest soil in the the rainforest is at ground level. Trees such as the Booyong, which have shallow roots, take advantage of the abundant leaf litter.
The palmate leaf structure (leaflets radiating from a central point) is an easily recognisable features. You can observe the leaves when you look into the crown of the Booyong of the seventh span on the Tree Top Walk.
Booyongs flower in autumn and in a good year their white flowers carpet the rainforest floor.
The brown, woody seed of the Booyong has a broad wing attached that spins like a helicopter rotor as is it carried along by the wind.
