Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – an interim threat classification status has not been assessed by the NZTCS panel.

Very low-growing sprawling shrub with densely white-hairy twigs bearing clustered pairs of thick blue-green leaves, hairy white flowers and white fruit inhabiting coastal areas south to Nelson. Leaves 3-6mm long by 2-3mm, underside shiny.
Endemic. North Island: widespread, often common from Three Kings, throughout coastal Northland, thence mostly easterly south to the Wairarapa and south Taranaki. South Island: Tasman Bay (Astrolabe Passage), Marlborough Sounds.
Coastal. Rock outcrops, cliffs, sometimes in scrub.
A small to medium-sized prostrate shrub; stems moderately stout but flexible, up to 300 mm long. Branching notably sympodial with some laterals. Branchlets densely covered by matted white hair. Internodes 1–3 mm long. Older stems slightly hairy, grey-brown. Node buttresses smooth, black, lunate, masked by hair on young stems. Leaves decussate but usually distichously arranged, ascendant on youngest branchlets, patent later. Lamina 3–6 × 2–3 mm, thick, narrow-elliptic to ovate, flat or slightly keeled. Tip usually obtuse. Stomata abundant adaxially, none or rare abaxially. Abaxial surface glistens. Inflorescences 5–7-flowered compact, receptacles very hairy. Involucral bracts 4, similar in size to adjacent leaves. Plants gynodioecious. Flowers small, white, outside very hairy, inside sparsely hairy in upper tube. Calyx lobes opening in salverform fashion or ascendant. Female tube 1.8 mm long, ovary portion wrinkled, 1.5 mm, calyx lobes 1.2 × 1 mm. hermaphrodite tube 3.8 mm long, ovary portion 2.5 mm, calyx lobes 2 × 1.5 mm. Anther dehiscence semi-latrorse. Ovary with a tuft of long hair on summit. Fruits white, fleshy, opaque 5 × 3.5 mm. Seeds broad ovoid 3 × 1.8 mm.

Unknown. Burrows (2009) states: Summer
Probably easily grown from semi-hardwood cuttings and rooted pieces. As with other pimelea seed is probably difficult to germinate.
pimelea: Pimeleoides means “resembling Pimelea’’, a genus in the family Thymelaeaceae (Greek, -oides = resembling, like).
urvilleana: After D’Urville Island, which is named in honour of Jules Sébastien César Dumont d’Urville (23 May 1790 - 8 May 1842) - a French explorer, naval officer and rear admiral, who explored the south and western Pacific, Australia, New Zealand and Antarctica.

Notes on taxonomy
Burrows (2009) offers a very clear (for the first time ever for this species) interpretation of Pimelea urvilleana, and as such splits it into two subspecies. Based on that interpretation he argues that P. urvilleana subsp. urvilleana is close to if not already extinct. However, it is stated that the genome survives in hybrids. No evidence is provided to back that claim up beyond empirical observations and some minor morphological assessments of herbarium material. Subsequent field work has shown that Pimelea urvilleana subsp. urvilleana is widespread, often common and not threatened. The distinctions offered for Pimelea urvilleana subsp. nesica seem dubious especially as specimens with characters of both subspecies can be found on the same plant.
