Leucopogon pilifer, commonly known as thready beard-heath,[2] is a species of flowering plant in the heath family Ericaceae and is endemic to south-eastern Australia. It is a low-lying, dwarf, often mat-forming shrub with long branches, oblong to lance-shaped leaves and crowded, white spikes of densely bearded flowers arranged in groups of between 4 and 9.

Description

[edit]

Leucopogon pilifer is a low-lying, dwarf shrub with branches up to about 30 m (98 ft) long, and that often forms mats, its young branchlets densely covered with soft hairs. The leaves are more or less erect, oblong to lance-shaped, 3.1–7.3 mm (0.12–0.29 in) long and 0.7–1.3 mm (0.028–0.051 in) wide on a petiole up to 0.5 mm (0.020 in) long. The leaves are more or less glabrous, with 3 to 5, more or less parallel veins visible on the lower surface. The flowers are erect and arranged on the ends of branches and in upper leaf axils in groups of between 4 and 9 with white bracteoles 0.9–1 mm (0.035–0.039 in) long. The sepals are egg-shaped, 1.4–1.6 mm (0.055–0.063 in) long, and the petals are white, 0.9–1.2 mm (0.035–0.047 in) long and joined at the base, forming a tube, with densely bearded lobes about 1.0 mm (0.039 in) long. Flowering occurs from October to February, and the fruit is a glabrous, slightly ridged drupe 1.5–2.0 mm (0.059–0.079 in) long.[2][3][4]

Taxonomy

[edit]

Leucopogon pilifer was first formally described in 1859 by Norman Arthur Wakefield in The Victorian Naturalist from specimens collected by James Hamlyn Willis on the Bogong High Plains in 1947.[4][5] The specific epithet (pilifer) means "bearing hairs".[6]

Distribution and habitat

[edit]

Thready beard-heath grows in heath and shrubland at higher altitudes from near Barrington Tops in north-eastern New South Wales to the higher eastern ranges of Victoria, and on the Central Plateau of Tasmania.[2][3][7]
