Olearia newbeyi is a species of flowering plant in the family Asteraceae and is endemic to the south-west of Western Australia. It is a shrub with broadly linear to narrowly oblong leaves, and dull purple, daisy-like inflorescences.
Description
Olearia newbeyi is a shrub that typically grows up to {{cvt|30|cm}} high and {{cvt|30–35|cm}} wide, its stems and leaves with a few glandular hairs. The leaves are crowded in bunches pressed against the stems, scattered along older stems, broadly linear to narrowly oblong, {{cvt|2–12|mm}} long and {{cvt|0.8–4|mm}} wide and sessile. Both sides of the leaves are medium green with a few glandular hairs and a heart-shaped base. The heads or daisy-like "flowers" are arranged in panicles on the ends of branches on a peduncle {{cvt|2–20|mm}} long and are {{cvt|5–8|mm}} in diameter with a cup-shaped involucre at the base. Each head has 76 to 85 dull purple ray florets, the ligule {{cvt|1.5–2.0|mm}} long, surrounding 6 to 11 disc florets. Flowering occurs in January and the fruit is an achene {{cvt|0.6–1.1|mm}} long, the pappus with eighteen to thirty barbed bristles.{{cite journal |last1=Lander |first1=Nicholas S. |title=New species of Olearia (Asteraceae: Astereae) from Western Australia. |journal=Nuytsia |date=1990 |volume=18 |pages=100–101 |url=https://florabase.dpaw.wa.gov.au/science/nuytsia/546.pdf |access-date=13 June 2022}}{{FloraBase|name=Olearia newbeyi |id=33622}}
Taxonomy
Olearia newbeyi was first formally described in 2008 by Nicholas Sèan Lander in the journal Nuytsia from specimens collected by Kenneth Newbey in 1985.{{cite web |title=Olearia newbeyi |url=https://biodiversity.org.au/nsl/services/rest/name/apni/631355/api/apni-format |website=APNI |accessdate=13 June 2022}} The specific epithet (newbeyi) honours the collector of the type specimens.{{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=260 |edition=3rd}}
