Acacia citrinoviridis

Acacia citrinoviridis, commonly known as black mulga, river jam, milhan or wantan, is a tree in the family Fabaceae. Endemic to Western Australia, it occurs along creeks and rivers in the semi-arid land north of Carnarvon and Meekatharra.

Black mulga grows to a height of about 8 metres (26 ft). It usually has just one trunk. Like most Acacia species, it has phyllodes rather than true leaves. These are a grey-olive colour, and may be up to 12 centimetres (4.7 in) long and about 1 centimetre (0.4 in) wide. The flowers are yellow, and held in cylindrical clusters. The pods are around 8 centimetres (3 in) long and have a lemon-green felty covering. From a distance black mulga is similar to mulga but it can be distinguished by its dark bark.
