Description

Pityrodia spenceriis an erect shrub that has its branches densely covered with woolly, ash-coloured, branched hairs. The leaves are arranged inwhorls of three or scattered, heart-shaped to egg-shaped with a point on the end, mostly 10–20 mm (0.39–0.79 in) long and 5–8 mm (0.20–0.31 in) wide on a short petiole, or more or less sessile. The leaves are densely covered with branched, ash-coloured hairs. The flowers are sessile and arranged singly in leaf axils. There are leaf-like bracts and linear bracteoles 3.5–5 mm (0.14–0.20 in) long at the base of the flowers. The sepals are 7–8 mm (0.28–0.31 in) long and joined at the base forming a bell-shaped to top-shaped tube with five lance-shaped lobes 4–5 mm (0.16–0.20 in) long. The five petals are white, 8–10 mm (0.31–0.39 in) long and joined at the base to form a more or less cylindrical tube with two "lips". The upper lip is about 3 mm (0.12 in) long and the other four are narrowly egg-shaped or oblong and about 2 mm (0.079 in) long. The fruit is oval, softly-hairy and 3–4 mm (0.12–0.16 in) long. [2]
