May not be this genus. A bit of a guess. In lakeshore herbfield.
This seems to be a missed species! Growing in wet area on edge of a mountain tarn. Leaves densely tomentose on both surfaces, Capitula 2 mm wide, leaves 1 cm long. Single, short flowerhead, midrib under the leaf visible and rhizomatous habit.
Uphill of Coppermine Saddle at SE corner of Wooded Peak, under low beech/podocarp forest. Abundant at this site.
