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.

Brief description
Low growing sprawling shrub with densely hairy dark twigs bearing pairs of slightly overlapping oval leaves that have hairs on the underside, hairy white flowers and red fruit inhabiting rocky areas of the northern South Island. Leaves 5-8mm long by 2-3mm wide, hairs glisten, straight.
Distribution
Endemic. New Zealand: South Island (western Nelson, central and eastern Marlborough, north Canterbury (head of the Clarence River)
Habitat
Montane to alpine. A component of tall tussock grassland and also on rock outcrops and cliffs, especially marble, limestone and sandstone (occasionally on ultramafics).
Detailed description
Robust, much-branched, procumbent, decumbent or sometimes semi-upright shrubs up to 250 mm tall; stems usually stiff, up to 400 mm long. Branching mainly sympodial. Young stems brown, densely covered in short, white to greyish or yellowish, fine to coarse, appressed to ascending hairs. Internodes 1-2 mm, densely hairy. Older stems thick (to 12 mm), glabrate, dark grey-brown. Node buttresses lunate, 0.2 mm long, smooth, brown, usually not very prominent on leafless stems. Leaves decussate, ascending, loosely imbricate, on short (0.5 mm), red petioles. Lamina 5-8 × 2-3 mm, medium to dark green, ovate to broadly ovate, slightly keeled; tip sharply acute; base cuneate; abaxial surface densely to moderately densely covered by short, straight, appressed, glistening white, straight hairs; stomata on both adaxial and abaxial surfaces. Inflorescences terminal, 3-7-flowered. Involucral bracts wider than adjacent leaves (5.0-6.0 × 3.5-3.9 mm). Receptacles with dense short hairs. Plants gynodioecious. Flowers white, on short (0.3 mm) pedicels, densely covered outside with short hairs; inside hairless. Female tube to 3.5 mm long, ovary portion 2 mm, calyx lobes 1.5 × 1.0 mm; hermaphrodite tube to 6 mm long, ovary portion 2 mm, calyx lobes 2.0 × 1.5 mm. Anther dehiscence introrse. Ovary with a cluster of long hairs at summit and sparse, short hairs to base. Fruits ovoid, fleshy, red, 5.0 × 3.5 mm. Seeds 2.5 × 1.8 mm.
Similar taxa
Pimelea nitens subsp. nitens is distinguished from subsp. aspera by the dark grey-brown colour of the older stems, mostly ovate to broad-ovate leaves with mostly sharply acute (rarely blunt) apices, which are abaxially furnished with shorter mostly appressed, straight, glistening white hairs.
Flowering
December - February
Flower colours
White
Fruiting
February - April
Propagation technique
Unknown. Probably easily grown from semi-hard and hardwood cuttings.
Threats
Burrows (2011) offers little information noting that Pimelea nitens subsp. nitens is not well known but that it (p. 87) “seems to be relatively common in western Nelson, but that a thorough survey of its situation is needed. No attempt to provide a threat status using the New Zealand Threat Classification System (see Townsend et al. 2008) was made but it seems clear from the little information provided that an interim threat assessment of “Data Deficient” is probably appropriate.
Etymology
pimelea: Pimeleoides means “resembling Pimelea’’, a genus in the family Thymelaeaceae (Greek, -oides = resembling, like).
