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.

Raoulia mackayi Buchanan, Gnaphalium traversii var. mackayi (Buchanan) Kirk, Gnaphalium mackayi (Buchanan) Cockayne, Euchiton mackayi (Buchanan) Anderb.


Endemic. North Island: Ruahine and Tararua Ranges; South Island: throughout Stewart Island: Mt Anglem only


Montane to alpine bogs, herbfield and grassland, often in wet sites and commoner in wetter areas


Perennial herb with much-branched stems terminating in leafy rosettes and usually forming mats, 10-70 mm tall. Leaves mostly in basal rosettes; basal leaves cuneate to short petiole, densely white-tomentose on both surfaces including mid-vein but usually excluding petiole on upper, plane, elliptic to broad-elliptic or spathulate, usually obtuse, sometimes acute, mucronate, 3-20 × 2-6 mm; cauline leaves 1-few, apetiolate, reduced upwards and becoming ovate-triangular to linear, amplexicaul and finally scalelike. Capitula c.2-4 mm diameter, usually solitary, very rarely 2 together; subtending leaves < capitula; scape terminal, simple, erect, amongst leaves at flowering, usually elongating somewhat at fruiting. Involucral bracts elliptic-oblong, obtuse to subacute, 4.5-6.0 mm long; stereome green or tinged reddish purple at apex; lamina pale brown, with darker band at base; gap and margins clear or tinged reddish purple. Achenes glabrous, c.1.2 mm long

Similar Taxa

Both Argyrotegium mackayi and A. nitidulum 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.
