Acacia grasbyi
Miniritchie grows is a shrubby tree to a height of about four metres. It typically has several main stems. These are often twisted, and are always covered in distinctive minni ritchi bark, which peels in small curly flakes. Like most "Acacia" species, it has phyllodes rather than true leaves. These are rigid, round in cross-section with a diameter of about a millimetre, and up to nine centimetres long. The flowers are yellow, and held in cylindrical clusters about three centimetres long and five millimetres in diameter, on stalks about two centimetres long. The pods are brown, up to eleven centimetres long, with tight constrictions between the seeds.
