Turpentine bush (Eremophila clarkei)

Description

Eremophila clarkei is an erect shrub growing to a height of between 0.6 m (2 ft) and 4 m (10 ft) wide with branches that are flattened near their tip, glabrous and very sticky due to the presence of resin. The leaves are dark green, widely spaced and arranged alternately along the stems, linear to narrow elliptic in shape and mostly 16–45 mm (0.6–2 in) long and 3–6.5 mm (0.1–0.3 in) wide. The leaf margins may be smooth, wavy or toothed. The flowers are borne singly in leaf axils on an s-shaped, flattened stalk which is 15–27 mm (0.6–1 in) long. There are 5 linear, green to purple sepals differing slightly in length, 10–15.5 mm (0.4–0.6 in) long and lance-shaped. The petals are 20–40 mm (0.8–2 in) long and joined at their lower end to form a tube. The petal tube is white, pink, mauve or purple. The outside of the tube and petal lobes are hairy while the inner surface of the lobes is glabrous and the inside of the tube is filled with woolly hairs. The lowest petal lobe covers the opening of the petal tube. Flowering occurs from March to October and is followed by fruits which are dry, woody oval to cone-shaped and 5.5–9 mm (0.2–0.4 in) long.
