It is restricted to a few areas in the north of the state.Eremophila pentaptera is a shrub with speading branches and which grows to a height of 40 cm (20 in). The older branches are greyish-white and are often grooved. The leaves are lance-shaped with the narrower end towards the base, succulent, mostly glabrous, mostly 12–29.5 mm (0.5–1 in) long and 3–7 mm (0.1–0.3 in) wide. They are usually dished on the upper surface and convex on the lower side.The flowers are borne singly in leaf axils on a glabrous stalk 3.5–6.5 mm (0.1–0.3 in) long which has 5 distinct ribs, especially near the outer end. There are 5 mostly glabrous, lance-shaped sepals which are 9–12.5 mm (0.4–0.5 in) long. The sepals are often tinged purple and are triangular in cross-section. The petals are 22–32 mm (0.9–1 in) long and are joined at their lower end to form a tube. The petal tube is light purple to reddish-violet on the outside and the inner half of the lowest petal lobe and inside of the tube are cream-coloured with faint lilac spots. Both surfaces of the petal tube and lobes are glabrous except the middle of the lower lobe and the inside of the tube which have long, soft hairs. The 4 stamens are about the same length as the petal tube. The fruits are oval-shaped to bottle-shaped, usually 6–9 mm (0.2–0.4 in) long and have eight prominent ribs.
