Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

NVS Species Code


The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

Dicotyledonous Herbs - Composites


Gnaphalium nitidulum Hook.f., Euchiton nitidulus (Hook.f.) Anderb.


Indigenous. South Island, Marlborough and near Arthurs Pass. Present in Australia


Alpine, favouring open stony ground within tussock grassland, herbfield. Also on scree.


Stoloniferous perennial with much-branched, densely packed stems terminating in leafy rosettes and usually forming compact cushion or ball-like mats, 20-40 mm tall. Leaves mostly in basal rosettes, imbricating, initially erect then reflexing with age, basally scarious to almost glabrous though usually with a few floccose hairs near junction with stem, upper portion clad in appressed, sericeous, glossy brown tomentum; basal leaves slightly narrowed to broad sheathing petiole, densely sericeous on both surfaces including mid-vein but not petiole, keeled toward apex, lamina narrow-oblong to spathulate, obtuse, 5-12 × 2-4 mm; cauline leaves 1-2, narrow. Capitula solitary, subsessile or sessile c.5-8 mm diameter; subtending leaves < capitula; scape terminal, simple, erect, amongst leaves at flowering, elongating only to just above leaves at fruiting. Involucral bracts scarious, narrowly elliptic-oblong, subacute, 6.9-8.0 mm long; stereome yellow-green; lamina very pale brown, sometimes darker at base; gap and margins clear to mid-brown. Achenes 1.0-1.2 mm long, with scattered appressed hairs, becoming glabrous. Pappus of c.30-36 filiform hairs, c.6.0-6.2 mm. long.

Similar Taxa

Both Argyrotegium nitidulum and A. mackayi are mat-forming species with solitary terminal flowers. Argyrotegium nitidulum is distinguished from A. mackayi by the leaf hairs which are more or less straight, antrorse, appressed and glossy rather than tangled and white.


November - January


December - February

Propagation Technique

Difficult. Should not be removed from the wild.


While not actively threatened this is a very uncommon plant in New Zealand. To ensure its long term security it is important that all populations are routinely monitored. Some populations are especially vulnerable to plant collectors and to a lesser extent the spread of weeds.
