Leguminosae
Common names
Myall.
Description
Small tree with rounded crown and drooping branchlets; grows
up to 6 m. Narrow silvery grey leaves, 1 to 1.5 cm long and 0.3 to 0.9
cm wide and somewhat curved. Flowers in small heads in short axillary racemes,
yellow wattle type. Pods are winged, flat, and about 1.25 cm wide and 2.5
to 7.5 cm long.
Distribution
Occurs mainly south of the Tropic of Capricorn in Australia:
on the western plains of Queensland and New South Wales on heavy brown
and grey clays which are occasionally inundated, it is often pure stand.
Its roots forage widely and crops cannot grow near the trunk. Regenerates
from seed; seedling growth is rapid, young trees reaching 1.3 m in four
years. The young plants are relished by sheep and cattle and should be
protected until they are 45 cm high. The tree is attacked by gregarious
bag caterpillars (family Liparidae) which often defoliate much of the tree
(Stannard and Condon, 1958).
