Blackwood - ''Acacia melanoxylon'' is a common tree in South-eastern Australia, It is named for the dark heartwood of the tree which produces a timber much favoured in furniture making.
+
The '''Australian Blackwood''' (''Acacia melanoxylon (Leguminosae)'') is an [[Acacia]] [[species]] native in eastern [[Australia]]. The species is also known as '''Sally Wattle''', '''Lightwood''', '''Hickory''', '''Mudgerabah''', '''Tasmanian Blackwood''' or '''Black Wattle'''. This tree species grows fast and tall, up to 45 m height. It has a wide ecological tolerance, occurring over an extensive range of soils and climatic conditions, but develops better in colder climates. Control of its invasion of natural vegetation, commercial timber plantations and farmland in several host counties incur considerable costs, but its timber value and nursing of natural forest succession provides a positive contribution.

''Acacia melanoxylon (Leguminosae)'' grows as an unarmed, evergreen tree 8-15 (sometimes up to 45) m high, with a straight trunk and dense and pyramidal to cylindrical  crown , sometimes with heavy spreading branches. The leaves are [[bipinnate]] (feathery) on seedlings and coppice shoots turn into [[phyllode]]s. Phyllodes are 7-10 cm long, greyish turning dark dull-green, straight to slightly curved, with 3-7 prominent longitudinal veins and fine net-veins between; often bipinnate on young plants and coppice shoots. Pale yellow, globular flower heads are followed by Reddish-brown pods, narrower than phyllodes, slightly constricted, twisted; flat roundish shiny black seeds 2-3 mm long, seeds almost encircled by pinkish-red seed stalks (aril)" (Henderson, 1995. In PIER, 2002). It has a shallow root system with dense, surface feeder roots.

The Australian Blackwood (Acacia melanoxylon (Leguminosae)) is an Acacia species native in eastern Australia. The species is also known as Sally Wattle, Lightwood, Hickory, Mudgerabah, Tasmanian Blackwood or Black Wattle. This tree species grows fast and tall, up to 45 m height. It has a wide ecological tolerance, occurring over an extensive range of soils and climatic conditions, but develops better in colder climates. Control of its invasion of natural vegetation, commercial timber plantations and farmland in several host counties incur considerable costs, but its timber value and nursing of natural forest succession provides a positive contribution.

Acacia melanoxylon (Leguminosae) grows as an unarmed, evergreen tree 8-15 (sometimes up to 45) m high, with a straight trunk and dense and pyramidal to cylindrical crown , sometimes with heavy spreading branches. The leaves are bipinnate (feathery) on seedlings and coppice shoots turn into phyllodes. Phyllodes are 7-10 cm long, greyish turning dark dull-green, straight to slightly curved, with 3-7 prominent longitudinal veins and fine net-veins between; often bipinnate on young plants and coppice shoots. Pale yellow, globular flower heads are followed by Reddish-brown pods, narrower than phyllodes, slightly constricted, twisted; flat roundish shiny black seeds 2-3 mm long, seeds almost encircled by pinkish-red seed stalks (aril)" (Henderson, 1995. In PIER, 2002). It has a shallow root system with dense, surface feeder roots.

Blackwood (Acacia melanoxylon) is a common tree in South-eastern Australia, It is named for the dark heartwood of the tree which produces a timber much favoured in furniture making.

The tree can grow to 30m in height and has very dense dark green foliage. As a young tree it shows typical Acacia foliage, with bipinnate leaves, but these are quickly replaced by expanded leaf stalks known as phyllodes that resemble simple parallel-veined leaves.
