Olearia speciosa is a species of flowering plant in the family Asteraceae and is endemic to Victoria in Australia. It is a straggly, open shrub with egg-shaped to elliptic leaves, and white and yellow or brownish, daisy-like inflorescences.
Description
[edit]Olearia rudis is a straggly, open shrub that typically grows to a height of up to about 1 m (3 ft 3 in), its branchlets densely woolly-hairy with white to fawn or pinkish hairs. It has egg-shaped to elliptic leaves 20–80 mm (0.79–3.15 in) long and 8–40 mm (0.31–1.57 in) wide on a petiole up to 1 mm (0.039 in) long. The edges of the leaves have irregular teeth and the lower surface is densely woolly-hairy. The heads or daisy-like "flowers" are arranged in loose corymbs on a peduncle 10–50 mm (0.39–1.97 in) and are 22–35 mm (0.87–1.38 in) in diameter. Each head has 4 to 7 white ray florets, the ligule 9–13 mm (0.35–0.51 in) long, surrounding 10 to 14 yellow or brownish disc florets. Flowering occurs from November to January and the fruit is a glabrous achene, the pappus 4.5–6.0 mm (0.18–0.24 in) long.[2][3]
Taxonomy
[edit]Olearia speciosa was first formally described in 1907 by John Hutchinson in The Botanical Magazine from plants raised from seed collected in the Botanic Gardens, Melbourne in 1888.[3][4] The specific epithet (speciosa) means "showy".[5]
Distribution and habitat
[edit]This olearia grows in scattered locations in cool, moist forest in southern Victoria.[2]
Conservation status
[edit]Olearia speciosa is listed as "poorly known in Victoria" on the Department of Sustainability and Environment's Advisory List of Rare Or Threatened Plants In Victoria.[6]
