Detailed description
Large tufted herb with leaves all radical, sheaths imbricate around stout stem. Lamina 120–300 × 25–65 mm, coriaceous, oblong-to elliptic-lanceolate; upper surface glabrous; lower surface densely clad in closely appressed white satiny tomentum, midrib prominent, dark; apex acute to subacuminate, usually distinctly apiculate; margins flat, rather distantly denticulate, narrowed to base or very short broad petiole. Sheath ± 40 × 15 mm, coriaceous, glabrous, ribbed. Scape stout to rather slender, angled or flattened, ± 180–600 mm long. Bracts linear-subulate, c. 25–35 mm long (outer up to 50 mm). Capitula 50–70 mm diameter, subtending bracts similar to upper scape-bracts. Involucral bracts 10–25 mm long; inner narrow, glabrous, glandular-pubescent; outer broader, lanceolate, tomentose without. Ray florets numerous, c. 25 mm long, narrow; limb gradually widening to obtuse 3-toothed apex. Disk florets tubular to funnelform, c. 7–8 mm long. Achenes 5–6 mm long, obovoid-compressed to subfusiform, densely clad in short ascending hairs. Pappus hairs c. 5–7 mm long, white to sordid-white, becoming rufous.
Distribution
Endemic. New Zealanbd: South Island (Fiordland).
Habitat
Coastal to lowland to lower subalpine rocky places, grassland, herb-field.
Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2022-2023 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website. This report includes replaces all previous NZTCS lists for vascular plants. Previous assessments can be found here.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – these interim threat classification statuses has not been assessed by the NZTCS panel.

Cultivation
Occasionally available from specialist native plant nurseries.
Etymology
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
