It is an open, straggly shrub with linear to narrowly egg-shaped leaves with irregular teeth or lobes on the edges, and white flowers in clusters of 3 to 15.

Commersonia rugosa is an open, straggly shrub that typically grows to 2 m (6 ft 7 in) high and wide, its new growth covered with brownish, star-shaped hairs.
