Description

The most common of two tree daisy species which cover over 50% of North East Island.
Up to c. 8m tall, mostly shorter (due to undermining by titi/muttonbird burrows, which causes a more horizontal growth form.) Diameter up to c.50-60cms.
Leaves covered, above and below, with white tomentum, which wears off on the upper surface. Leaf edges crenate.
Flowering uncommon in 2013, but developing in some patches of forest by mid December. Florets dark purple.

Description

Compound flowers in c. 11 umbels on each main stem. flowers white to mauve. The only Anisotome species growing on the Snares. One of two 'megaherb' species growing on the Snares. It appears that a plant known from the sinkhole area is now absent (Colin Miskelly pers. comm). The South-West Promontory site was not located, although not specifically searched for. Found near the razorback and west coast of the South Promontory near Olearia forest, growing among Poa tennantiana, Poa astonii and Stilbocarpa robusta. Numerous healthy plants at the two sites.

About

Plant species recorded on the Snares Islands (with this in mind has anyone got an image of Histiopteris incisa observed on the Snares?). Moss and liverwort species will be added in 2014, as identifications are completed.
It would be great if people could add observations and images from Broughton Island and Alert Stack, aswell as Poa astonii from Toru and Rua Islets.
