Eremophila scaberula is a heath-like shrub which grows to a height of between . Its branches have prominent ridges leading down from the leaf bases and are slightly sticky due to the presence of
resin. The leaves are arranged in
whorls of 3 or 4 along the branches and are linear in shape, mostly long, about wide, rough to the touch and slightly sticky. The flowers are borne singly in leaf axils on short,
glabrous, sticky stalks long. There are 5 tapering egg-shaped, glabrous, sticky
sepals which are about long with some narrower than others. The
petals are long and are joined at their lower end to form a tube. The petal tube and lobes are dark lilac-coloured to purple and white with brown to purple spots inside the tube. The inside and outside surfaces are glabrous except that the middle part of the lower lobe and the inside of the tube are hairy. The 4 stamens are fully enclosed in the petal tube. Flowering occurs between July and October and is followed by fruits which are small, dry, woody, cone-shaped, long and have a glabrous, papery covering. ==Taxonomy and naming==
