Detailed description
An erect much-branched shrub up to 0.8 m tall and 500-60 mm wide. Branching mainly sympodial and semi-fastigiate. Young branchlets densely covered in appressed white hairs; internodes 1-2mm long. Older stems glabrate, darker brown to black. Node buttresses small (0.3mm long) lunate, masked by hairs on young branchlets, not prominent on leafless stems. Leaves decussate, ascending, loosely imbricate, on very short petioles (0.3 mm) or sessile. Lamina broad elliptic or broad ovate, 5.0-8.0 × 2.5-5.0 mm, densely covered on both surfaces with appressed, short, white hairs, adaxially concave, mid-vein obscure, acute, base cuneate. Stomata on both adaxial and abaxial surfaces. Inflorescences terminal, 5-10-flowered, sometimes in small groups. Receptacle with dense, short hairs. Involucral bracts 4, larger than adjacent leaves (to 7 × 3 mm). Plants gynodioecious. Flowers white, scented, on short (0.2 mm) pedicels, very hairy outside, internally glabrate. Female tube 3.5 mm long, ovary portion 2 mm, calyx lobes 1.2 × 1.2 mm; hermaphrodite tube 6 mm long, ovary portion 2 mm, calyx lobes 3.0 × 1.5 mm. Anther dehiscence introrse. Ovary with a tuft of hairs at summit. Fruits fleshy, (white) or red, ovoid 4.2 × 3.5 mm. Seeds 2.5 × 1.7 mm.
Similar taxa
Pimelea concinna is endemic to the north-eastern South Island within which area is easily recognised by its upright growth habit (reaching up to 0.8 m tall) and red fruits. Within that area it could only be confused with Pimelea aridiula subsp. olga, which is superficially similar but has longer, and narrower leaves (6-15 × 2-3 mm cf. 5.0-8.0 × 2.5-5.0 mm in P. concinna), which are less distinctly hairy, and with the hairs are notably longer. Pimelea aridula subsp. olga has dry brown fruits while those of P. concinna are fleshy and coloured red
Distribution
Endemic. South Island: Inland Nelson, Marlborough and North Canterbury (extending just into the Waiau-uha catchment)
Habitat
Lowland to montane. Inhabiting dry, rocky hillsides with short grassland and scrub.
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.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – these interim threat classification statuses has not been assessed by the NZTCS panel.

Threats
Pimelea concinna is not listed by de Lange et al. (2011). Burrows (2011) also concludes that the while species is not as yet threatened it is “declining” through land development, with topdressing, oversowing, burning and beef cattle grazing, it is moderately abundant, still, in undeveloped areas, particularly on very rocky hillsides. The threat status of Pimelea concinna may need to be re-evaluated

Propagation technique
Easily grown from semi-hardwood cuttings. Does best in a free draining, sunny site, planted within a rich. fertile soil. Dislikes competition from taller plants and humidity. Will not long tolerate being shaded out. An excellent pot plant or small shrub for a rockery.
