Description
Olearia plucheacea is an erect, open shrub that typically grows to a height of up to 1.5 m (4 ft 11 in), its stems and leaves covered with simple and glandular hairs. The leaves are arranged alternately, scattered along the branchlets, sticky, thread-like to narrowly linear, 12–45 mm (0.47–1.77 in) long and 1–5 mm (0.039–0.197 in) wide. The heads or daisy-like "flowers" are arranged in dense panicles on the ends of branches on a peduncle up to 35 mm (1.4 in) long, the leaves grading to the narrowly conical involucre at the base. Each head is 9.5–13.5 mm (0.37–0.53 in) in diameter with 5 to 7 white ray florets, the ligule 3.5–4.5 mm (0.14–0.18 in) long, surrounding 3 to 5 yellow disc florets. Flowering occurs from August to October and the fruit is an achene 1.7–2.4 mm (0.067–0.094 in) long, the pappus with 25 to 38 bristles.[2][3]
