Description

Leptospermum petraeum is a spreading, rigid shrub that typically grows to a height of about 3 m (9.8 ft). The bark on older stems is thin and flaky, the younger stems hairy with an indistinct flange. The leaves are aromatic, broadly elliptical with a sharp point on the tip, about 15 mm (0.59 in) long and 5–6 mm (0.20–0.24 in) wide with a distinct petiole. The flowers are borne singly on short side shoots and are white, about 22 mm (0.87 in) wide. There are broad, yellowish-brown bracts and bracteoles at the base of the flower bud. The floral cup is mostly glabrous, about 4 mm (0.16 in) long and the sepals are hairy, 4–6 mm (0.16–0.24 in) long. The petals are about 7 mm (0.28 in) long and the stamens 2.5–3 mm (0.098–0.118 in) long. The flowering period is uncertain but the fruit is a capsule about 7–8 mm (0.28–0.31 in) in diameter, and that remains on the plant until it is burnt. [2] [3]

Taxonomy and naming

Leptospermum petraeum was first formally described in 1989 by Joy Thompson in the journal Telopea , based on plant material she collected in Kanangra. [3] [4] The specific epithet (petraeum) is from a Latin word meaning "growing among rocks", referring to the habitat of this species. [3] [5] [6]

Distribution and habitat

This tea-tree grows is only known from the type population where it grows on an exposed rocky outcrop. [2] [3]
