Eremophila glabra, commonly known as tar bush, is a plant in the figwort family, Scrophulariaceae and is endemic to Australia.

In spite of its scientific name, not all forms of the plant are glabrous but most have many small, raised glands on the stems, flowers and leaves.

[2][3][4] The flowers are red, orange, yellow or yellowish green, lack spots and are arranged singly or in pairs in the leaf axils on a stalk which is 3–10 mm (0.1–0.4 in) long.

The petals, which give the flowers their colour are 20–30 mm (0.8–1 in) long and joined in a tube with 5 lobes at the end.

Flowering occurs between early autumn and summer (March to December in Australia) and is followed by fruit which are oval to almost spherical, about 4–9 mm (0.2–0.4 in) in diameter, glabrous, dry or fleshy and dark brown.

Subspecies glabra is the most widespread and it occurs in a wide range of soils and vegetation associations, although only in the drier areas of the continent.
