Acacia melanoxylon

ACACIA MELANOXYLON                    Mimosaceae

Large erect tree to 30 metres with dense crown and dark furrowed bark on trunk. Phyllodes are dull grey-green, elliptical, straight or curved 4-10 cm long,, 10-25 mm wide, with 3-5 prominent longitudinal veins; glands near base. Dense pale yellow heads, globular, of 30-50 flowers on stout stalks 5-10 mm long, solitary or in short racemes of 2-8 heads. Pods flattish, curved or coiled 4-12 cm long, 6-10 mm broad, margins thickened, slightly constricted between seeds. Suckers readily from damaged roots; young leaves bipinnate. A valuable commercial timber which is used extensively for furniture making, panelling and for craftwork. Note: In recent times it's been discovered that the "powder" formed when
working this wood, can be carcinogenic.  Therefore special care, such as using a mask, needs to be taken at that time. Once the wood is made up and sealed, it is perfectly safe.

Flowering August - October. Widespread, in wet gullies and forests.

Silver Wattle

Tree to 30 m tall with grey mottled smooth bark and felty or hoary branchlets, flowering when very small. Leaves bipinnate, minutely hairy, blue-green, with 10-20 pairs of pinnae, raised glands at base of each pair; smallest leaflets in 30-40 pairs, linear, crowded 4-6cm long.

Pods light purplish-brown, oblong, smooth, 5-8cm long, 8-10 mm broad, in good seasons forming conspicuous masses. Flowering
July-August.Widespread from coast to mountains, largest in moist valleys and colonising after fires or other disturbances in eucalypt forests.

Acacia verticillata

ACACIA VERTICILLATA                  Mimosaceae
Prickly Moses

A wattle with stalked ovoid heads, widespread especially in damp areas, gullies and along creeks. Usually a straggling bush up to 3 m but a small tree in favourable conditions. The
arrangement of the spiky phyllodes (apparent leaves) in rings gives the name verticillata.
These vary in width from 1-4 mm in different forms. The dark green phyllodes and golden flowers make an attractive display along river banks in early Spring.
Flowering September to November. Widespread in damp areas.

ACACIA LEPROSA var. GRAVEOLENS                        Mimosaceae               Varnish Wattle
(previously A. verniciflua)

Attractive, profusely flowering shrubby tree to about 5 m. favouring damp habitats and clearings. The phyllodes are light green, narrow and lance-shaped with two prominent veins, shiny and often sticky. Yellow flowers in dense globular heads on short stalks, 2 or 3 per leaf axil.  Pods elongated, leathery, constricted between seeds. Flowering early Spring.  Propagation from scarified seed.

Acacia leprosa var graveolens

ACACIA MUCRONATA var MUCRONATA            Mimosaceae
Acacia mucronata

Found only in Tasmania.  Variable shrub in height and phyllode form.

Phyllodes may be narrow to lanceolate up to 20 cm.

Profuse creamy-yellow flowers in Spring.

Propagation from scarified seed.

Very hardy.

ACACIA GENISTIFOLIA                    Mimosaceae
Acacia genistifolia (upright form)
(Upright form)
This spreading wattle heralds the arrival of Spring, being one of the earliest wattles to flower. It has gone through many name changes including A. diffusa, cuspidata and prostrata.  Its current name refers to the phyllodes (flattened leaf stalk which takes the function of a leaf, the true leaf blade being suppressed) having some similarity to a species of broom, probably Genista anglica.

Acacia genistifolia is a native of Tasmania, NSW and Victoria. It’s a plant that grows in dry sclerophyll habitats and has brilliant yellow ball flowers.  Winifred Curtis, the famous botanist, called it A. diffusa and described it as a variable shrub 2-3m high, but it can be either prostrate or upright. The prostrate form has a spread of about 2m. The form comes true from cuttings. The leaves have pungent points, something to remember when pruning or weeding nearby.
