Olearia hectori
Encyclopedia
Olearia hectori is a species of flowering plant
in the Asteraceae
family.
It is found only in New Zealand
.
Olearia hectorii, also known as Hectors tree daisy, is one of the most threatened of New Zealand's eight olearia species, all of which are part of a national recovery plan.
Olearia hectorii or Hectors tree daisy is deciduous, up to 9.5m tall, with deeply furrowed, cork-like bark on the trunk and older branches. Young branches and branchlets are smooth-barked and bronze-red with four ribs that produce a squarish cross-section.
Leaves are arranged in clusters of opposite pairs. They're a pale moss-green colour and roughly oval in shape. Flowers are in clusters of two to six, any time between October to early December, and can begin before the new leaves appear.
Olearia hectorii primarily occupies wet, cold valley floors and hill slopes, often where mountain and hill-country streams disgorge onto the plains.
Total population size is approximately 4500 individuals, from approximately 90 sites. The largest population occurs in Marlborough's Clarence catchment, where approximately 2000 plants are known.
