Description
Olearia pannosa is a spreading undershrub or shrub that typically grows to a height of up to and forms a root suckers. The branchlets are covered with woolly, Y-shaped hairs. The leaves are arranged alternately, egg-shaped or heart-shaped, long and wide on a petiole up to long, the upper surface becoming glabrous and the lower surface covered with hairs similar to those on the branchlets. The heads or daisy-like "flowers" are arranged singly on the ends of branches and are wide on a peduncle long, the involucre hemispherical and woolly-hairy. Each flower has 8 to 24 white ray florets and 18 to 50 yellow disc florets. Flowering occurs from September to November and the achenes are long, the pappus long.Taxonomy
Olearia pannosa was first formally described in 1852 by William Jackson Hooker in his Icones Plantarum from specimens collected near the Murray River in South Australia.In 1853, Ferdinand von Mueller described Eurybia cardiophylla in the journal Linnaea from specimens collected on Mount Remarkable in South Australia, but in 1986, David Cooke reduced this species to Olearia pannosa subsp. cardiophylla D.A.Cooke. That name, and that of the autonym are accepted by the Australian Plant Census.
