Olearia teretifolia is a species of flowering plant in the family Asteraceae and is endemic to south-eastern Australia. It is a bushy shrub with lance-shaped, egg-shaped or elliptic leaves arranged in opposite pairs, and white and yellow, daisy-like inflorescences.
Olearia viscosa is a bushy shrub that typically grows to a height of up to about 3 m (9.8 ft) and has more or less glabrous, sticky branchlets. The leaves are arranged in opposite pairs, lance-shaped to narrowly egg-shaped or elliptic, 40–110 mm (1.6–4.3 in) long and 10–40 mm (0.39–1.57 in) wide on a short petiole. The upper surface is sticky or covered with resin glands, the lower surface whitish or yellowish and densely hairy. The heads or daisy-like "flowers" are arranged in moderately dense groups on the ends of branches, each head 8–15 mm (0.31–0.59 in) in diameter with a narrowly conical involucre 3.5–5 mm (0.14–0.20 in) long at the base. Each head has one or two white ray florets, the ligule 3–7 mm (0.12–0.28 in) long, surrounding 3 to 5 yellow disc florets. Flowering occurs in November and December and the fruit is a ribbed, cylindrical achene 3–4 mm (0.12–0.16 in) long, the pappus 5–8 mm (0.20–0.31 in) long. [2] [3]
This daisy was first formally described in 1867 by Jacques Labillardière who gave it the name Aster viscosus in his book Novae Hollandiae Plantarum Specimen . [4] [5] In 1867, George Bentham changed the name to Olearia viscosa in Flora Australiensis . [6] The specific epithet (viscosa) means "abounding in bird lime", that is "sticky" or "viscid". [7]
