Description
editOlearia orientalis is a bushy shrub that typically grows to a height of 0.5–2 m (1 ft 8 in – 6 ft 7 in), its young branchlets often sticky. The leaves are alternately along the branchlets, egg-shaped with the narrower end towards the base, 18–37 mm (0.71–1.46 in) long and 9–14 mm (0.35–0.55 in) wide with two to four pairs of teeth on the edges. The heads or daisy-like "flowers" are arranged singly on the ends of branchlets and are 8–11 mm (0.31–0.43 in) wide on a peduncle 12–55 mm (0.47–2.17 in) long. Each head has 14 to 20 white ray florets, the ligules 3–6 mm (0.12–0.24 in) long, surrounding 16 to 26 yellow disc florets. Flowering occurs in most months and the achenes are flattened, 2.0–2.8 mm (0.079–0.110 in) long, the pappus with 31 to 40 bristles in two rows.[2]
Taxonomy and naming
