Native – Endemic taxon
Category

Structural class
Trees & Shrubs - Dicotyledons
Simplified description
Shrub with erect hairy branches bearing pairs of pointed green thin leaves that are hairy underneath, hairy white flowers and black fruit inhabiting the south to the northern South Island. Leaves 15-25mm long by 3-5mm wide, widest towards base. Flowers cause stem to branch.
Flower colours
White, Yellow
Detailed description
An erect, grey-green, leafy shrub up to 1 m tall. Branches are slender and straight, with prominent leaf scars. Bark orange-brown. Young branchlets have whitish hairs. The grey-green, soft lance-shaped leaves are up to 25 mm long, with pale silky hairs on their undersides. The black fleshy fruits are very conspicuous, terminating the branch ends wherever flowers have been present.
Similar taxa
Pimelea prostrata is a common component of coastal cliffs and shrubland vegetation. It has several variable forms but the leaves are smaller (3 to 6 byƒn1 to 3 mm) than of P. tomentosa, its habit prostrate to sprawling and it has smaller, less conspicuous white fleshy fruits. Sand daphne (Pimelea arenaria) has a similar habit but only occurs in dunes and dune hollows, has shorter, more rounded leaves than P. tomentosa and smaller red fruits.
Distribution
Endemic to New Zealand, occurring throughout the North Island and northern South Island.
Habitat
Open cliff tops, in scrub, frost flats, track sides and other seral habitats.
Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.

Family
Taxonomic notes
New Zealand Pimelea urgently require a full taxonomic revision using modern techniques. The treatments of Burrows (2009a, b et seq.) offer a useful foundation for further revision. Luckily Pimelea tomentosa is a well marked species and is not likely to require taxonomic adjustment.
Endemic taxon
Yes
Endemic genus
No

No
Ecology
Flowering
Flowering specimens may be seen throughout the year.
Fruiting
Fruiting specimens may be seen throughout the year.
Propagation technique
Very easy to grow from fresh fruit and semi-hardwood cuttings. This species forms an attractive small shrub and is tolerant of a wide range of soil types and conditions from drought prone sites to frosty situations. It does best in infertile soils.

Etymology
pimelea: Pimeleoides means “resembling Pimelea’’, a genus in the family Thymelaeaceae (Greek, -oides = resembling, like).
NVS code
