Current conservation status
The conservation 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). 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.

Endemic. Stewart Island: south of, and including Mt Rakeahua - mostly in the Tin Range
Lowland to subalpine in poorly draining grassland, tussockland, shrubland, mires and similar boggy ground and in seepages within rock crevices
Silvery-white to white solitary, clumped or extensive patch forming herb. Branches slender, variable, clad in persistent leaf-remnants; branchlets densely clad in imbricate, ascending, spreading to recurved leaves. Lamina variable 10-60 × 5-15 mm, narrow-linear, linear to lanceolate, subcoriaceous, upper and lower surfaces silvery-white, upper surface ribbed, pellicle persistent, underside with inrolled margin and raised purplish midrib. Scapes 100–150 mm long, purplish, slender, clothed with fine woolly tomentum; bracts numerous, linear-lanceolate, silvery tomentose, with broad, purplish sheathing bases. Heads 25 mm diameter; involucral bracts brownish, pubescent, spreading at the tips; ray florets white, obcuneate, rounded at the tip. Achenes 3 mm long, linear, pointed at the base, slightly widening towards the tip, silky.
On Stewart Island (where this species is endemic) it is mostly likely to be confused with plants attributed to C. graminifolia and C. alpina. From plants of the C. graminifolia aggregate it differs by the silvery-white mostly narrowly linear to linear, inrolled leaves (rather than mostly flat (or inrolled) leaves which are brownish to brown-green and often patterned above; and by the purplish rather than pale green or white scapes. From C. alpine, C. polyvena differs by the larger size, and broader, less inrolled, silvery-white rather than very narrow, tightly inrolled, brown or grey-green leaves, purple rather than pale scape, and much larger capitula. Celmisia polyvena is part of the C. gracilenta - C. graminifolia complex.
November - December
February - April
Pappate cypselae are dispersed by wind (Thorsen et al., 2009).
Unknown. Probably easy from fresh seed, and plants are likely to require a shaded site, planted within a permanently moist soil.
A naturally uncommon species that does not appear to be actively threatened
celmisia: Apparently named after Kelmis, one of Idaean Dactyls, a group of skilled mythical beings associated with the Mother Goddess Rhea in Greek mythology. Kelmis, whose name means ‘casting’, was a blacksmith and childhood friend of Zeus, son of Rhea and later king of the gods. In Ovid’s ‘Metamorphoses’, Kelmis is described as offending Zeus who turned him into adamant so he was as hard as a tempered blade
polyvena: Many-veined (leaves)
