Acacia melanoxylon is certainly a weed here in California. These compound flower clusters (axillary racemes) generally contain only 2-8 of the small globular flower clusters. The tree belongs to the Plurinerves section of Acacia and is one of the most wide ranging tree species in eastern Australia and is quite variable mostly in the size and shape of the phyllodes. Proceedings of the National Synthesis Symposium on the ecology of biological invasions [edited by Macdonald, I.A.W. 5-Year Review: Summary and Evaluation : US Fish and Wildlife Service.48 pp. 80 pp. Acacia melanoxylon is one of the most wide-ranging tree species in eastern Australia and considerably variable, particularly in phyllode size and shape in which the variation is continuous (Farrell & Ashton 1978; Playford et al.

ACIAR Monograph No. They are densely arranged into small rounded clusters (5-10 mm across), each containing numerous (30-56) flowers. Tree Characteristics. On young plants, partially formed phyllodes can be seen which bear twice-compound (bipinnate) leaves at their tips. The flower clusters are borne on stalks (peduncles) 5-14 mm long and are alternately arranged on a short branch (6-40 mm long) emanating from a 'leaf' fork (phyllode axil). Biocontrol agents against alien invasive plants in fynbos. ACIAR Monograph. It may be nailed or screwed with ease, but gluing may produce variable results. Large trees can be killed by ring barking (Tunison, 1991). Blackwood (Acacia melanoxylon) is often confused with other native wattles, particularly lightwood (Acacia implexa) and western coastal wattle (Acacia cyclops).
