Eremophila cuneifolia, commonly known as pinyuru, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to the north-west of Western Australia. It is a spreading, sticky shrub with wedge-shaped leaves, coloured sepals and usually deep purple flowers.
The plant is a spreading shrub growing to a height of between 0.4 and 1.8 metres (1 and 6 ft) with hairy branches and with branches and leaves that are thickly covered with sticky, shiny resin. The leaves are arranged alternately and clustered near the ends of the stems, mostly 5–16 millimetres (0.2–0.6 in) long, about 3–14 millimetres (0.1–0.6 in) wide, wedge-shaped or heart-shaped but with a distinct small point at the tip. They are thick and stiff and the top surface of the leaves is glabrous while the lower surface is hairy.
The flowers are borne singly in leaf axils on hairy stalks 1–3.5 millimetres (0.04–0.1 in) long. There are 5 cream-coloured to pale reddish-purple, slightly overlapping, egg-shaped sepals differing in size from each other but mostly 8.5–26 millimetres (0.3–1 in) long. The petals are 16–26 millimetres (0.6–1 in) long and joined at their lower end to form a tube. The petal tube is usually deep purple on the outside, sometimes paler, and white inside with purple spots. There are scattered hairs on the outside of the tube and on the lobes but the tube is filled with long, soft hairs. The 4 stamens are fully enclosed within the tube. Flowering occurs mostly from June to October and is followed by fruits which are oval to cone-shaped, shiny and 5.5–9 millimetres (0.2–0.4 in) long.
