Description
Spyridium coactilifolium is a small perennial shrub with rusty-coloured short, matted, dense hairs on the branches.  The leaves are oval to egg-shaped, rounded at the base, blunt and notched at the apex,  long and densely covered with soft, star-shaped hairs. The flower petals are velvety-white, usually 4 or 5, entire or notched at the apex and about  long. The bracts are silky, brown, and egg-shaped with small hairs on the margins. Flowering occurs  from December to February and the fruit is a brown capsule, egg-shaped with the narrower end at the base, hard, thin, brittle, smooth except near the base.
