Description
editOlearia suffruticosa is a sticky shrub or undershrub that typically grows to a height of 40–70 cm (16–28 in) and has a woody base and slender, short-lived glabrous stems with few branches. The leaves are arranged alternately, sessile, linear and grass-like, 3–24 mm (0.12–0.94 in) long and 0.5–0.9 mm (0.020–0.035 in) wide and more or less glabrous. The heads or daisy-like "flowers" are arranged in leafy panicles on the ends of branches, on a peduncle up to 50 mm (2.0 in) long, each head with a bell-shaped involucre at the base. Each head has 12 to 20 white to pink ray florets, the ligule 7–8 mm (0.28–0.31 in) long, surrounding 16 to 22 yellow and pink disc florets. Flowering occurs from January to May and the fruit is an achene about 1 mm (0.039 in) long, the pappus about 2 mm (0.079 in) long.[2][3][4][5][6]
Taxonomy
editOlearia suffruticosa was first formally described in 1985 by David Alan Cooke in the Journal of the Adelaide Botanic Gardens from specimens collected near the Bool Lagoon in 1963.[5][7] The specific epithet (suffruticosa) means "somewhat woody".[8]
Distribution and habitat
editClustered daisy-bush grows in heathland in swampy areas in the far south-east of South Australia, the south-west of Victoria near Glenisla, Casterton and Dergholm, and between Capertee and Wallerawang in New South Wales.[2][3][4][9]
Conservation status
editThis olearia is listed as "endangered" under the Victoria Government Flora and Fauna Guarantee Act 1988[3] and as "vulnerable" in the Department of Sustainability and Environment's Advisory List of Rare Or Threatened Plants In Victoria.[9][10]
