Olearia quercifolia, commonly known as oak-leaved olearia,[2] is a species of flowering plant in the family Asteraceae, and is endemic to the Blue Mountains in New South Wales. It is a shrub with elliptic to egg-shaped leaves with the narrower end towards the base, and white and yellow daisy flowers.
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described in 1836 by Augustin Pyramus de Candolle in his Prodromus Systematis Naturalis Regni Vegetabilis, from an unpublished description of specimens collected by Allan Cunningham.[3][4] The specific epithet (quercifolia) means "oak-leaved".[5]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]
