Olearia ferresii is a species of flowering plant in the family Asteraceae and is endemic to central Australia. It is an erect, aromatic shrub with elliptic to lance-shaped leaves and white and yellow, daisy-like inflorescences.
Description
Olearia ferresii is an erect, aromatic shrub that typically grows to a height of up to about {{cvt|1.5|m}} and has prominently ribbed stems. The leaves are elliptic to lance-shaped, sometimes with the narrower end towards the base, {{cvt|40–115|mm}} long, {{cvt|5–30|mm}} wide and sessile. The leaves are covered with glandular hairs and the edges of the leaves sometimes have small teeth. The heads or daisy-like "flowers" have white, rarely pale pink or pale purple ray florets surrounding yellow disc florets. Flowering occurs in most months and the fruit is a hairy achene about {{cvt|3–4|mm}} long.{{cite web |title=Olearia ferresii |url=http://eflora.nt.gov.au/factsheet?id=620 |publisher=Northern Territory Government |access-date=7 April 2022}}{{cite web |title=Olearia ferresii |url=http://www.flora.sa.gov.au/cgi-bin/speciesfacts_display.cgi?form=speciesfacts&name=Olearia_ferresii |publisher=State Herbarium of South Australia |access-date=7 April 2022}}{{FloraBase|name=Olearia ferresii|id=8135}}
Taxonomy
This daisy bush was first formally described in 1862 by Ferdinand von Mueller who gave it the name Eurybia ferresii in Fragmenta Phytographiae Australiae from specimens collected by John McDouall Stuart in the MacDonnell Ranges.{{cite web|title=Eurybia ferresii|url= https://id.biodiversity.org.au/instance/apni/529884|publisher=APNI|access-date=7 April 2022}}{{cite book |last1=von Mueller |first1=Ferdinand |title=Fragmenta Phytographiae Australiae |volume=3 |date=1862 |publisher=Victorian Government Printer |location=Melbourne |page=18 |url=https://www.biodiversitylibrary.org/item/7220#page/19/mode/1up |access-date=7 April 2022}} In 1867, George Bentham changed the name to Olearia ferresii in Flora Australiensis.{{cite web|title=Olearia ferresii|url= https://id.biodiversity.org.au/instance/apni/533011|publisher=APNI|access-date=7 April 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=487 |url=https://www.biodiversitylibrary.org/item/41807#page/495/mode/1up |access-date=7 April 2022}} The specific epithet (ferresii) honours John Ferres, the Victorian Government Printer at the time.{{cite book |last1=Sharr |first1=Francis Aubi |last2=George |first2=Alex |title=Western Australian Plant Names and Their Meanings |date=2019 |publisher=Four Gables Press |location=Kardinya, WA |isbn=9780958034180 |page=198 |edition=3rd}}
