Description
Acacia dealbata
is a large shrub to tall tree with an erect stem usually ranging in height from
2-15 m, but attaining 30 m in parts of Tasmania and Victoria, Australia. It
often is seen as a spreading shrub but where space allows it has a rounded
crown. Bark is brown grey to dark grey, often mottled white (due to lichen
growth). Young stems and new growth are smoother and lighter in colour. A. dealbata produces root suckers and
coppices easily. A. dealbata has
silvery green to dark green densely hairy bipinnate leaves 6-11 cm long. Leaves
have 7-26 pairs of pinnae which are 15-30 mm in length. There are 20-50 pairs
of leaflets on each, linear oblong, 2-5 mm long and 0.4-0.7 mm wide. The glands
are prominent with one on the petiole and a raised gland at the junction
between pairs of pinnae. A. dealbata
exhibits a diurnal rhythm of pinnule movement in which the leaves open by day
and close by night. Flowers are normally golden yellow but sometimes are lemon
or pale yellow in colour with 25-35 flowers in globular heads on peduncles ca.
6 mm long found in the terminal, axillary racemes and panicles. Pods are bluish
glaucous, oblong in shape, 58-80 mm long and 8-12 mm wide, margins slightly
thicker and raised and irregular with constrictions between seeds. The seed is
black and oblong 4-6 x 2-3 mm, arranged longitudinally in the pod with a short
seed stalk and a cap-like aril. Seeds are shed and remain viable in the ground
for many years (Cabi, 2019).
