Olearia macrodontia (Mountain Holly or Arorangi in New Zealand or New Zealand Holly elsewhere) is a small sub-alpine evergreen tree endemic to New Zealand, from the plant family Asteraceae. 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 means the two species are often confused with one another. It is found from lowland to sub-alpine forests from the East Cape of the North Island of New Zealand southwards throughout the South Island and Stewart Island, from 450–1,200 metres (1,480–3,900 ft) in altitude.
Olearia macrodontia is a shrub to spreading small tree that grows 1.5–6 metres (4 ft 10 in–19 ft 8 in) tall. Its leaves are 5–10 centimetres (2.0–3.9 in) long, 2.5–4 cm (0.98–1.6 in) wide, with undulating and coarsely serrated margins, greyish green above. It's flowers are white with yellow centres and grow in large, rounded, much branched corymbs.[1]
