Detailed description
Sprawling subshrub arising from a multicipital stock and forming mats up to 2 m diameter. Branchlets stout, c. 5 mm diameter, clad in leaf remains and emitting cord-like roots along most of length. Living leaves in rosulate tufts at branchlet tips. Lamina 20-60 × 10-20 mm, oblanceolate, light green sometimes glaucous, tip subacute, base tapering gradually into sheath, margin finely dentate; lower and upper surfaces glabrous except for a narrow and sometimes inconspicuous band of deciduous white hairs along the margin; midrib and one to two pairs of lateral veins prominent. Sheath membranous and glabrous, broad. Scape glandular, sometimes with a few deciduous eglandular hairs in lower part, stout, 120-200 × 2-3 mm; bracts many, foliaceous, glandular, oblanceolate to oblong, midrib and one pair of lateral veins prominent. Receptacle subglobose, c.15 mm diameter. Involucral bracts in several series, loosely imbricate, up to 15 mm long, subulate, acuminate, slightly recurved, densely clothed in stalked glandular hairs, margins fimbriate towards tip. Ray florets up to 25 mm long, limb wide, tube with stalked glandular hairs. In disc florets, corolla tube clad in biseriate eglandular hairs of clavate form. Pappus bristles unequal, up to 7 mm long, 20-30 in number, teeth close and short. Achene 2.5-3.5 × 1.0 mm, compressed, densely clad in long bifid hairs.
Similar taxa
Somewhat similar to Celmisia sinclairii and C. prorepens, species with which it does not grow, and from both of which it differs in leaf lamina colour, shape and venation, by having a narrow band of deciduous white hairs on the lamina margin; by the large bracts on the scape and by the distinctly erect involucral bracts
Distribution
Endemic. South Island: Fiordland National Park in scattered localities between Caswell and Thompson Sounds and inland to Lake Te Anau
Habitat
Subalpine to alpine. Forming mats on steep, damp, rocky bluffs. Favouring base-rich rocks, especially marble and limestone.
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.

Life cycle and dispersal
Pappate cypselae are dispersed by wind (Thorsen et al., 2009).
Propagation technique
Difficult. Can be grown from fresh seed but requires a shaded, permanently moist situation. Does best in a soil that has been enriched in lime, and should be grown amongst limestone or marble rocks
Other information
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
