Description edit

Leptospermum grandiflorum is a densely-branched shrub that typically grows to a height of 1.5–5 m (4 ft 11 in – 16 ft 5 in) or more and has rough bark on older branches and whitish young stems. The leaves are thick, greyish green, elliptical to broadly egg-shaped with the narrower end towards the base, mostly 10–15 mm (0.39–0.59 in) long and 4–8 mm (0.16–0.31 in) wide, tapering to a short, often twisted petiole. The flowers are arranged singly on short side branches on a pedicel about 1 mm (0.039 in) long and are about 20 mm (0.79 in) in diameter. The floral cup is dark and wrinkled, about 3 mm (0.12 in) long and more or less glabrous. The sepals are broadly egg-shaped to round, 2.5–3.5 mm (0.098–0.138 in) long and fall off as the fruit develops. The petals are white, about 8 mm (0.31 in) long and the stamens 4–5 mm (0.16–0.20 in) long. Flowering occurs from February to April and the fruit is a capsule 9–12 mm (0.35–0.47 in) wide that remains on the plant.[2]

Taxonomy and naming edit

Leptospermum grandiflorum was first formally described in 1821 by the British nurserymen Joachim, George and William Loddiges in their journal, The Botanical Cabinet.[3][4]

Distribution and habitat edit

This tea-tree grows on granite rocks in eastern Tasmania, mostly on or near the Freycinet Peninsula.[2]
