Olearia persoonioides

Olearia persoonioides is a bushy shrub that typically grows to a height of {{cvt|1.0–1.5|m}}. Its leaves are arranged alternately, oblong or egg-shaped with the narrower end towards the base, {{cvt|19–38|mm}} 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.{{cite book |last1=Rodway |first1=Leonard |title=The Tasmanian Flora |date=1903 |publisher=Tasmanian Government Printer |location=Hobart |page=74 |url=https://www.biodiversitylibrary.org/page/37374840#page/132/mode/1up |access-date=28 June 2022}}{{cite book |last1=Bentham |first1=George |last2=von Mueller |first2=Ferdinand |title=Flora Australiensis |volume=3 |date=1867 |publisher=Lovell Reeve & Co. |location=London |page=471 |url=https://www.biodiversitylibrary.org/item/41807#page/479/mode/1up |access-date=28 June 2022}}{{cite web |last1=Jordan |first1=Greg |title=Olearia persoonioides |url=https://www.utas.edu.au/dicotkey/dicotkey/AST/ast/sOlearia_persoonioides.htm |publisher=University of Tasmania |access-date=28 June 2022}}

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 {{cvt|4100|ft}} on Mount Wellington.{{cite web |title=Eurybia persoonioides |url=https://biodiversity.org.au/nsl/services/rest/instance/apni/531254 |publisher=Australian Plant Name Index |access-date=16 March 2025}}{{cite book |last1=de Candolle |first1=Augustin P. |title=Prodromus Systematis Naturalis Regni Vegetabilis |volume=5 |date=1836 |publisher=Sumptibus Sociorum Treuttel et Würtz |location=Paris |page=267 |url=https://www.biodiversitylibrary.org/item/7154#page/272/mode/1up |access-date=16 March 2025}} In 1867, the species was transferred to Olearia as O. persoonioides by George Bentham in his Flora Australiensis.{{cite web |title=Olearia persoonioides |url=https://biodiversity.org.au/nsl/services/rest/instance/apni/534889 |publisher=Australian Plant Name Index |access-date=16 March 2025}}
