Olearia gravis is a species of flowering plant in the family Asteraceae and is endemic to south-eastern Australia. It is a shrub with elliptic or egg-shaped leaves and white and yellow, daisy-like inflorescences.
Olearia gravis is a shrub that typically grows to a height of up to . Its leaves are arranged alternately along the branchlets, elliptic or egg-shaped, long and wide on a petiole up to long and with small point along the edges. The heads or daisy-like "flowers" are arranged singly on the ends of branches, and are in diameter on a peduncle up to long. Each head has 20 to 22 white ray florets surrounding 17 to 49 yellow disc florets. Flowering occurs from August to November and the fruit is a glabrous achene, the pappus with 31 to 39 bristles.[1]
This daisy-bush was first formally described in 1865 by Ferdinand von Mueller who gave it the name Aster gravis in his Fragmenta Phytographiae Australiae from specimens collected near Tenterfield.[2] [3] In 1867, George Bentham changed the name to Olearia glandulosa in Flora Australiensis.[4] The specific epithet (gravis) means "heavy" or "weighty".[5]
Olearia gravis grows in forest in mountain areas from south-east Queensland to the Blue Mountains in New South Wales.[6]
