Zieria adenodonta is a dense, bushy shrub which grows to a height of and has warty branchlets. The leaves are composed of three leaflets with the central one, long and wide with a stalk long. The leaflets are dark green and warty on the upper surface, light green and not wary on the lower side. The edges of the leaflets are slightly rolled under and have small teeth. They have an unpleasant smell when crushed. The flowers are white and are arranged in upper leaf
axils, usually in groups of five to eight, but sometimes as many as 27. The groups are usually shorter than the leaves. There are four more or less hairy, triangular
sepal lobes less than long. The four
petals are about long and slightly hairy. In common with other zierias, there are only four
stamens. Flowering occurs from May to September and is followed by the fruit which is a yellow-brown, egg-shaped
capsule containing one black seed. ==Taxonomy and naming==
