About

Olearia macrodonta (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 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 450–1,200 metres (1,480–3,940 ft) in altitude.

Olearia macrodonta is a shrub to spreading small tree that grows 1.5–6 metres (4 ft 11 in – 19 ft 8 in) tall.
