Olearia persoonioides is a species of flowering plant in the family Asteraceae and is endemic to Tasmania. It is a shrub with oblong or egg-shaped leaves and heads of dairy-like flowers.

Description

Olearia persoonioides is a bushy shrub that typically grows to a height of 1.0–1.5 m (3 ft 3 in – 4 ft 11 in). Its leaves are arranged alternately, oblong or egg-shaped with the narrower end towards the base, 19–38 mm (0.75–1.50 in) long with a rounded tip. They are shiny green on the upper surface and covered with silvery hairs on the lower side. The heads or daisy-like "flowers" are arranged in leafy panicles with 3 to 8 white ray florets surrounding 10 to 12 disc florets. Flowering occurs in January. ^{[2] [3] [4]}

Taxonomy

This species was first formally described in 1836 by Swedish botanist Augustin Pyramus de Candolle who named it Eurybia persoonioides in his book Prodromus Systematis Naturalis Regni Vegetabilis from specimens collected at a height of 4,100 ft (1,200 m) on Mount Wellington. ^{[5] [6]} In 1867, the species was transferred to Olearia as O. persoonioides by George Bentham in his Flora Australiensis . ^{[3] [7]}
