Olearia stuartii
# Olearia stuartii

Olearia stuartii is a species of flowering plant in the family Asteraceae and is endemic arid parts of inland Australia. It is compact, spreading shrub or undershrub with lance-shaped leaves and blue to mauve and yellow, daisy-like inflorescences.

## Description

Olearia stuartii is a compact, sticky, spreading shrub or subshrub that typically grows to a height of 0.25–1.0 m (9.8 in – 3 ft 3.4 in), the stems woody and covered with soft hairs. Its leaves are lance-shaped with the narrower end towards the base, mostly 4–28 mm (0.16–1.10 in) long, 2–6 mm (0.079–0.236 in) wide and sessile with 2 to 5 pairs of lobes on the edges. The heads or daisy-like "flowers" are arranged singly or in groups of up to four on the ends of branches and are pedunculate with a hemispherical involucre 5–6 mm (0.20–0.24 in) long at the base. Each head has 20 to 50 blue to mauve ray florets, the ligule 6–10 mm (0.24–0.39 in) long, surrounding 30 to 70 yellow disc florets. Flowering occurs from June to September and the fruit is a flattened achene about 3 mm (0.12 in) long, the pappus with 20 to 30 bristles 4–5 mm (0.16–0.20 in) long.

## Taxonomy

This daisy was first formally described in 1859 by Ferdinand von Mueller who gave it the name Eurybia stuartii in Fragmenta Phytographiae Australiae from specimens collected in western inland South Australia by John McDouall Stuart. In 1867 George Bentham changed the name to Olearia stuartii in Flora Australiensis. The specific epithet (stuartii) honours the collector of the type specimens.

## Distribution and habitat

Olearia stuartii grows in woodland on rocky hills, on ranges, near cliffs and rocky creek beds in inland Western Australia, the south of the Northern Territory, the north-west of South Australia and inland Queensland.
