Acacia quadrimarginea

Acacia quadrimarginea, commonly known as granite wattle or spreading wattle, is a tree in the family Mimosaceae. Endemic to Western Australia, it occurs through arid south-central Western Australia, it is common on granite, but also occurs on sand and clay, and is often seen along creeklines in rocky hills.

Granite wattle grows as a small tree up to six metres high, and often wider than it is high. Like most Acacia species, it has phyllodes rather than true leaves; these are green with a faint red margin, up to ten centimetres long, and slightly curved. The flowers are yellow, and held in cylindrical clusters; the pods are four sided and thick, up to fifteen centimetres long.
