Mueller Daisy-bush

Walsholaria muelleri is a compact or spreading shrub that typically grows to a height of 0.4–1.5 m (1 ft 4 in – 4 ft 11 in) and has sticky branchlets and leaves. The leaves are arranged alternately, scattered along the branchlets, spatula-shaped to egg-shaped with the narrower end towards the base, 5–14 mm (0.20–0.55 in) long and 2–8 mm (0.079–0.315 in) wide sometimes with toothed or wavy edges. The heads or daisy-like "flowers" are arranged singly on the ends of branches and are more or less sessile or on a peduncle up to 10 mm (0.39 in) long. There is a bell-shaped involucre at the base with four to eight rows of sticky bracts. Each head has seven to thirteen white ray florets, the ligule 4–15 mm (0.16–0.59 in) long, surrounding twelve to eighteen yellow disc florets. Flowering occurs from August to October and the fruit is a silky-hairy achene, the pappus with forty to fifty bristles.

Walsholaria muelleri grows in mallee woodlands or spinifex communities and is widespread in the south-west of Western Australia, the south of South Australia, north-western Victoria and the far south-west of New South Wales.
