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 southern Marlborough and North Westland south, and becoming more abundant in the southern part of the South Island.
Montane to subalpine. Inhabiting grassland, herbfield, damp seepages within rock outcrops and in damp boulder falls and talus
Stout tufted herb with strict, rigid, coriaceous leaves; leaf-sheaths densely imbricate around stems. Lamina 150-500 × 10-30 mm, linear-lanceolate, acuminate, subpungent; upper surface glabrous, with a stout pair of ribs (sometimes doubled) parallel to rather obscure midrib (often with a further pair ± developed either side); lower surface completely clad in closely appressed white satiny tomentum, midrib and lateral pair evident; margins ± recurved, gradually narrowed to sheath or with very short petiole; sheath 40-80 mm long, coriaceous, finely grooved, midrib prominent, both surfaces clad in deciduous white satiny tomentum. Scape ± 200-500 mm long, stout, clad in dense floccose hairs; bracts narrow-linear; lower with lamina up to c.80 mm long. Capitula 30-40 mm diameter; involucral bracts linear-subulate, acuminate, up to c.17 mm long, pale brown, ± floccose-hairy on back, glabrous within, midrib evident. Ray-florets ± 17-20 mm long, white, tube narrow-cylindric, limb narrow-oblong. Disk-florets 6-7 mm long, tubular, teeth minute. Achenes cylindric, grooved, 2-3 mm long, with minute stiff white hairs on ribs. Pappus-hairs up to c.7 mm long, slender, minutely barbellate
Allied to Celmisia armstrongii and C. lyallii. From Celmisia lyallii it is distinguished by the leaves which lack a sharp tip and which have a stout, parallel pair of veins either side of an obscure central midrib rather than a single prominent midrib. From Celmisia armstrongii, C. petriei differs by the absence of a broad yellow band either side of the midrib on the upper leaf surface.
November - February
December - April
Pappate cypselae are dispersed by wind (Thorsen et al., 2009).
Easily grown in a shaded site, planted within a permanently moist, free draining, acidic soil. Dislikes humidity and will not tolerate drying out. Best grown from fresh seed which should be sown immediately or stratified in a fridge or freezer for 1-3 months
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
petriei: Named after Donald Petrie (1846 -1925), Scottish born Otago botanist
