Detailed description
Decumbent, annual or rarely short-lived perennial herb, forming small circular patches on open ground. Rosette-leaves 15 × 5 mm long (sometimes more), lamina obovate or broadly spathulate, obtuse, petiole broad; upper surface hairy except towards base, undersurface almost or quite glabrous, hairs of upper leaf surface tapering to soft ± flexuous tips; spreading. Lateral branches up to 8, decumbent, 30–150 mm long, usually branched, internodes usually less than leaves. Stem-leaves similar to rosette-leaves near base, becoming sessile above, bracts ovate to broad-oblong, distichous, exceeding internodes, diminishing in size, the lowest up to 10 × 5 mm. Cymes usually simple, few- to many-flowered, bracteate throughout; internodes usually less than bracts, sometimes very short; pedicels much smaller than calyx, very hairy. Calyx 3–5 mm long, usually lobed to halfway, lobes subacute; hairs long and ± retrorse short, not stiff or hooked. Corolla 3.0 mm diameter, cream to lemon-coloured, tube 2–3 mm long, cylindric, lobes narrow with obtuse tip; filaments very short, anthers < 1 mm long, wholly included, tips occasionally reaching level of scales; style less than calyx in length, stigma capitate. Nutlet 1.1–1.7 × 0.8–1.0 mm, ovate to ovate-elliptic, black, usually well immersed within calyx remnant.
Distribution
Endemic. North Island, South Island, Stewart Island/Rakiura and Campbell Island/Motu Ihupuku. From Mt. Hikurangi south through the main axial ranges to Fiordland, also on Banks Peninsula on the high points of Stewart Island. Evidently very uncommon on Campbell Island/Motu Ihupuku.
Habitat
Subalpine to alpine. Usually on stable scree, fellfield, stony ground and at the bases of rock tors in places subject to frequent immersion.
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.

Regional conservation statuses
The regional threat classification system leverages off the national assessments in the NZTCS, providing information relevant for the regional context. Otago conservation status information is sourced from the “Regional conservation status of indigenous vascular plants in Otago” Jarvie S et al. (2024) report.
