A genus of deciduous trees and shrubs known for their extremely bitter bark and medicinal …
Mainly inhabiting the coastal and sub-tropical rainforests of eastern Australia, Ailanthus imberbiflora var. imberbiflora grows as a tall, slender tree within dense forest canopies. This variety is recognized for its adaptation to high-humidity environments and well-drained volcanic soils.
It contributes significantly to the structural diversity of the local rainforest ecosystem.
This variety can grow up to 30 meters tall, featuring a smooth, pale grey bark that becomes slightly fissured as it matures. The compound pinnate leaves have leaflets that are distinctly asymmetrical, often falcate, and have a glabrous (hairless) surface.
Key morphological features include:
Flowers from November to January
The lightweight and straight-grained wood has been used historically in cabinet making, joinery, and for producing light packing cases.
It is also planted in forest restoration projects to help rebuild native subtropical rainforest habitats.
The wings of the samara fruit are aerodynamically structured, allowing them to spin and drift significant distances from the parent tree.
Additionally, it serves as a host plant for several native Australian caterpillar species.
