Characteristics:
Bark is rough and fissured. Phyllodes (modified leaves) resemble needles from 1.5 - 4.5 inches long. They are flat and end in softly curved innocuous tips. The phyllodes are spaced ½ inch apart, giving each branch a “loose” appearance. Flowers are small yellow puffs- 2 to 5 clustered together in the leaf ails. Fruits are legumes, 3-4 inches long, and papery with a width of about 1/4 inch. They are flat and constricted between the seeds. The seeds are small, black, and very hard.

Cultivation Notes:
A combination of events must occur for seedlings to establish: high late-summer rains, sheeting water flows which scarify the seeds (and presumably flush out ants that carry off the seeds and destroy them), shallow burying of seeds, follow-up rains that encourage seedlings, and low herbivore populations. In Western Australia, these events only occur together on average every 20 years.
Ethnobotany:
The wood of Acacia papyrocarpa was used by the Aborigines for musical instruments and tools. The blue, cloud-like appearance of the Western Myall is often used in landscaping as a focal point, but needs plenty of room to spread.
