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. South Island: Widespread from Nelson south to Southland
Montane to alpine. In grassland, herbfield and fellfield. Sometimes on rock outcrops
Robust densely branched subshrub forming dense patches up to c.1 m diameter and up to 100 mm tall; branchlets close-set, densely clad in imbricate leaves forming compacted rosettes. Leaves erect, becoming reflexed, sheaths persistent. Lamina 10.0-30.0 × 1•5-3.0 mm, linear to linear-subulate, coriaceous, rather rigid; both surfaces densely clad in short appressed white matted hairs; apex obtuse to sub-acute, sometimes subcucullate or apiculate; slightly narrowed at base to pale membranous sheath ± = lamina, ± clad in deciduous matted hairs. Scape reduced to minute stalk densely clad in floccose hairs, sometimes elongating to c.50 mm at fruiting stage and then hairs sparse or absent, ebracteate. Capitula 10-20 mm diameter or more, at first at least closely subtended by leaves; involucral bracts pale, slender, linear-subulate, up to 12 mm long, ± scarious, pilose (with hairs long-persistent at apex). Ray-florets c.15-17 mm long, white; linear, slightly expanded at tips; disk-florets c. 8 mm long, narrow-funnelform, flaring at 5-toothed apex. Achenes 3-4 mm long, cylindric-compressed; hairs on rather obscure ribs short, rather stiff. Pappus usually white; hairs up to 9 mm long, minutely barbellate
Can only be confused with Celmisia argentea. Celmisia argentea is confined to Otago and Southland. It is mainly distinguished by its smaller size and much shorter leaves (3.0-5.0 × 0.5-1.5 mm cf. 10.0-30.0 × 1.5-3.0 mm).
October - February
November - April
Pappate cypselae are dispersed by wind (Thorsen et al., 2009).
Difficult. Best grown from fresh seed but can be grown from cuttings. Should be planted in a free draining, moist soil. Excellent in a pot in an alpine house, or planted in a south-facing rockery. Dislikes humidity and will not tolerate drying out.
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
sessiliflora: With unstalked flowers
