Description
editProstanthera cruciflora is an erect, strongly aromatic shrub that typically grows to a height of 1.5–2 m (4 ft 11 in – 6 ft 7 in) with branchlets densely covered with glands. Its leaves are greyish green, egg-shaped, 6–20 mm (0.24–0.79 in) long and 8–15 mm (0.31–0.59 in) wide on a petiole 3–10 mm (0.12–0.39 in) long, and densely glandular. The flowers are arranged in groups of about eight, the sepals about 8 mm (0.31 in) long, forming a tube about 3.5 mm (0.14 in) long with two lobes, the upper lobe about 2.5 mm (0.098 in) long. The petals are 6–9 mm (0.24–0.35 in) long and white with yellow streaks on the lower lobe. Flowering occurs from August to December.[2][3]
Taxonomy and naming
editProstanthera cruciflora was first formally described in 1967 by James Hamlyn Willis in the journal Muelleria.[3][4] The specific epithet (cruciflora) is "an allusion to the cross-shaped lower lip of the corolla".[3]
Distribution and habitat
editThis mint bush grows in heath on exposed rock outcrops in the Mount Kaputar National Park and on nearby ranges.[2]
