Description

Leionema elatius is a shrub that grows to 2–5 m (6 ft 7 in–16 ft 5 in) high with either smooth stems or with star-shaped hairs. The leaves are flat, lance-shaped, oblong or narrowly oval to spoon-shaped, 1.5–3.5 cm (0.59–1.38 in) long, 3–10 mm (0.12–0.39 in) wide, upper surface shiny and smooth with a distinctive midrib below. The inflorescences are at the end of branches crowded by the leaves, pedicels and peduncles both slim. The calyx lobes are wide-triangular shaped and fleshy. The flower petals are white to light yellow, 3–4.5 mm (0.12–0.18 in) long and glandular. The fruit are about 4 mm (0.16 in) long and furrowed. Flowering occurs in spring. [2]

Taxonomy and naming

Tall phebalium was first formally described in 1859 by Ferdinand von Mueller, who gave it the name Eriostemon elatior in Fragmenta phytographiae Australiae from specimens collected near Tenterfield. [3] [4] In 1998, Paul G. Wilson changed the name to Leionema elatius and the change was published in the journal Nuytsia . [5] [6] The specific epithet (elatius) is derived from the Latin meaning "taller". [7]

Wilson described two subspecies and the names are accepted by the Australian Plant Census:

Distribution and habitat

Leionema elatius grows mostly on the ranges north of Bulahdelah and far south-eastern areas of Queensland. [6]
