Description

Olearia mooneyi is a densely-foliaged shrub that typically grows to a height of up to {{cvt|2|m}} or a tree to {{cvt|4|m}}. Its leaves are arranged alternately, crowded, narrowly to broadly elliptic or egg-shaped with the narrower end towards the base, {{cvt|40–100|mm}} long and {{cvt|15–35|mm}} on a petiole {{cvt|3–12|mm}} long. The upper surface of the leaves is glabrous, green and shiny, the lower surface pale brown and covered with fine woolly hairs. The heads or daisy-like "flowers" are arranged in dense corymbs and are about {{cvt|8|mm}} in diameter, the involucre about {{cvt|3|mm}} long and softly-hairy. Each head has about twelve white ray florets, the ligules about {{cvt|6|mm}} long, surrounding about eight pale yellow disc florets. Flowering occurs from November to January and the fruit is a hairy brown achene, the pappus with about twenty bristles.{{cite web |title=Olearia mooneyi |url=https://profiles.ala.org.au/opus/foa/profile/Olearia%20mooneyi |publisher=Australian Biological Resources Study, Department of Agriculture, Water and the Environment: Canberra |access-date=30 May 2022}}

Taxonomy

Pumpkin bush was first formally described in 1874 by Ferdinand von Mueller who gave it the name Aster mooneyi in Fragmenta Phytographiae Australiae from specimens collected by "Lind" and [https://www.anbg.gov.au/biography/fullagar-james-p.html Fullagar] on the summits of Mount Lidgbird and Mount Gower.{{cite web |title=Aster mooneyi|url=https://biodiversity.org.au/nsl/services/rest/name/apni/537780/api/apni-format |website=APNI |accessdate=30 May 2022}}{{cite book |last1=von Mueller |first1=Ferdinand |title=Fragmenta Phytographiae Australiae |volume=8 |date=1875 |publisher=Victorian Government Printer |location=Melbourne |page=144 |url=https://www.biodiversitylibrary.org/item/7225#page/145/mode/1up |access-date=30 May 2022}} In 1896, William Hemsley changed the name to Olearia mooneyi.{{cite web |title=Olearia mooneyi|url=https://biodiversity.org.au/nsl/services/rest/name/apni/537780/api/apni-format |website=APNI |accessdate=30 May 2022}} The specific epithet honours Thomas Mooney (1842–1873), an early settler of Lord Howe Island who was interested in its plants.
