Wiki description:
Description 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. Acacia melanoxylon R. Br. ex Ait. f. foliage and seed pods Acacia melanoxylon R. Br. ex Ait. f. seeds
