Common names for it include Black Wattle, Acácia-negra (Portuguese), Australian Acacia, Australische Akazie (German), Swartwattel (Afrikaans), Uwatela (Zulu). This plant is now known as one of the worst invasive species in the world.[1]
The trees are unarmed, evergreen and grow six to 20 meters high. The branchlets are shallowly ridged; all parts finely hairy; growth tips golden-hairy. Leaves dark olive-green, finely hairy, bipinnate; leaflets short (1.5 - 4 mm) and crowded; raised glands occur at and between the junctions of pinnae pairs. Flowers pale yellow or cream, globular flower heads in large, fragrant sprays. Fruits dark brown pods, finely hairy, usually markedly constricted.[2][3][4]
