It is closely related to the narrow-leaved Olearia ilicifolia, with which it shares several characteristics including largely undulating and serrated grey-green leaves. These common characteristics mean the two species are often confused with one another. It is found in lowland to sub-alpine forests from the East Cape of the North Island of New Zealand southwards throughout the South Island and Stewart Island, at {{convert|450|-|1200|m}} in altitude. Olearia macrodonta is a shrub to spreading small tree that grows {{convert|1.5|-|6|m}} tall. Its leaves are {{convert|5|-|10|cm}} long, {{convert|2.5|-|4|cm|abbr=on}} wide, with undulating and coarsely serrated margins, greyish green above. Its daisy-like composite flowers are white with yellow centres and grow in large, rounded, much-branched corymbs.[2]Despite its common name, O. macrodonta is not closely related to the true hollies Ilex. The specific epithet macrodonta means "large-toothed", referring to the leaves.[3] This plant has gained the Royal Horticultural Society's Award of Garden Merit.[4] References1. ^{{cite web |title=BSBI List 2007 |publisher=Botanical Society of Britain and Ireland |url=http://www.bsbi.org.uk/BSBIList2007.xls |format=xls |archive-url=https://www.webcitation.org/6VqJ46atN?url=http://www.bsbi.org.uk/BSBIList2007.xls |archive-date=2015-01-25 |accessdate=2014-10-17 |deadurl=yes |df= }} 2. ^{{cite book|last=Metcalf|first=L.
