Description

Phebalium lowanense is a slender shrub that typically grows to a height of 0.6–0.8 m (2 ft 0 in – 2 ft 7 in) and is more or less covered with silvery or rust-coloured scales. The leaves are linear, 3–12 mm (0.12–0.47 in) long and about 1 mm (0.039 in) wide but with the edges strongly rolled under, so that they appear cylindrical. The upper surface of the leaves is glabrous and slightly scaly, and the lower surface is covered with silvery scales. The flowers are yellow and arranged in umbels on the ends of branchlets with up to six flowers, each flower on a thick pedicel 3–7 mm (0.12–0.28 in) long. The sepals are 3–4 mm (0.12–0.16 in) long and joined for about half their length, and densely covered with silvery scales and star-shaped hairs. The petals are egg-shaped, about 5 mm (0.20 in) long and 2.5 mm (0.098 in) wide, covered with silvery and rust-coloured scales on the back. Flowering occurs August to September. [3] [4] [5] [6]

Taxonomy and naming

Phebalium lowanense was first formally described in 1957 by James Hamlyn Willis in The Victorian Naturalist from specimens he collected near the border between South Australia and Victoria in 1948. [7]

Distribution and habitat

Lowan phebalium grows in open heathy mallee woodland in a restricted area in the Murray Darling Depression biogeographic region near the South Australia-Victoria border. [2]

Conservation status

This phebalium is classified as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 . The main threats to the species are changed fire regimes, weed invasion, and clearing of roadsides and tracks. [2]
