Description edit
Olearia quercifolia is a shrub that typically grows to a height of 2 m (6 ft 7 in). It has scattered elliptic to egg-shaped leaves with the narrower end towards the base arranged alternately along the stems, the leaves 10–50 mm (0.39–1.97 in) long and 7–25 mm (0.28–0.98 in) wide on a petiole up to 7 mm (0.28 in) long. The edges of the leaves are lobed and the lower surface is covered with yellow, woolly hairs. The heads or daisy-like "flowers" are arranged in leaf axils on a peduncle up to 50 mm (2.0 in) long, each head 21–30 mm (0.83–1.18 in) in diameter with 7 to 15 white ray florets and 18 to 29 yellow disc florets. Flowering occurs from July to December and the achenes are glabrous, the pappus with 27 to 42 long bristles.[2]
Taxonomy and naming edit
Olearia quercifolia was first formally described in 1836 by Augustin Pyramus de Candolle in his Prodromus Systematis Naturalis Regni Vegetabilis, from an unpublished description of specimens collected by Allan Cunningham.[3][4] The specific epithet (quercifolia) means "oak-leaved".[5]
Distribution and habitat edit
Oak-leaved olearia grows in swampy places in the Blue Mountains of eastern New South Wales.[2]
