Current conservation status
The threat classification 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. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Distribution
Endemic. South Island from Central Otago east to Fiordland.
Habitat
Alpine (> 1300 m a.s.l.), usually amongst rocks, on cliff faces or in fell field, and on gently sloping, rock strewn ridge summits
Features
Woody, gyndioecious, perennial herb forming compact mats up to 30 mm thick in patches up 1 m wide. Rhizomes densely packed together, crowded, more or less horizontal and ascending at tips, completely obscured by leaves; branches single or in 2-3-clustered and diverging aggregates, usually spaced at 5-30 mm intervals; living leaves densely imbricate on the upper 5 mm of stem; lower parts covered with dead persistent leaves. Short shoots absent. Roots arising from basal parts of stems, slender but firm, more or less woody up to 5 mm diameter. Leaves sessile, palmately divided, curved around stem, 4-6 x 4-5 mm; blade 3 mm long, dark green, falcate, firmly coriaceous, with scattered short eglandular hairs; margins lobed up to 7 times, these linear, subteret, acute to acuminate, cut to top of broad leaf base. Peduncles more or less equal to or > leaf length, up to 70 mm long, ebracteate or with 1 small bract, pilose hairy. Capitula not or just emergent from mat surface, 2-4 mm diameter; surface convex; involucre hemispherical; involucral bracts subequally biseriate, elliptic or oblong, membranous, dark-green with a wide, pale keeled midrib, glabrous with broad scarious margins. Pistillate capitula with 10-15 involucral bracts and 20-45 florets; florets 2.25 mm long, straight, yellow-red, corolla twice as long as wide, dentition equal. Staminate capitula with 8-12 involucral bracts, 0-8 pistillate florets and 10-35 staminate. Cypsela 1.3 x 0.65 mm, golden-brown, glossy, compressed, smooth or slightly wrinkled.
Similar taxa
The stout woody stems, mat forming habit and imbricate palmatifid leaves are unique to this species and set it apart from any other in the genus.

Life cycle
Papery cypselae are dispersed by wind and possibly attachment (Thorsen et al., 2009).
