Description
editProstanthera teretifolia is an erect to spreading, aromatic shrub that typically grows to a height of 0.3–1 m (1 ft 0 in – 3 ft 3 in) with branches that are densely hairy and glandular. The leaves are greyish green, more or less cylindrical, 5–16 mm (0.20–0.63 in) long and 0.5–0.9 mm (0.020–0.035 in) wide, sometimes with two or three lobes, on a petiole 0.6–1.8 mm (0.024–0.071 in) long. The flowers are arranged in groups on the ends of leafy branchlets, the sepals about 4 mm (0.16 in) long forming a tube 2–2.5 mm (0.079–0.098 in) wide with two lobes, the upper lobe 1.5–2 mm (0.059–0.079 in) long. The petals are bluish-purple, 8–9 mm (0.31–0.35 in) long forming a tube 4.5–5 mm (0.18–0.20 in) long. Flowering usually occurs from August to December.[2][3]
