Detailed description
Small subshrub with woody, often multicipital, stock; branches close-set, clad in persistent, imbricate leaf-remnants; living leaves rosulate at tips of branchlets. Lamina coriaceous, not or only slightly viscid, 25-50 × 2-6 mm, linear to linear-spathulate; upper surface clad in thin ± deciduous pellicle; lower in appressed somewhat soft to satiny white tomentum; midrib pale, usually evident; apex obtuse to subacute; margins entire or minutely denticulate. Base suddenly expanded into sheath ± 15 × 5-6 mm, glabrous, transculent, longitudinal veins fine. Scape slender, viscid, up to c. 150 mm long; bracts linear-subulate, remote, lower with lamina c.20 mm long. Capitula 20-40 mm diameter. Involucral bracts c.10 mm. long, linear-lanceolate, indurated towards base and pale brown, with very prominent midrib; upper half thin, floccose on margins and ± viscid. Ray-florets c.16 mm long, white, linear, ± glandular, limb much recurved when dry, apex 3-4-toothed. Disk-florets c.6 mm long, very narrow-funnelform, teeth c.1 mm long, ovate-triangular. Achenes c.3 mm long, cylindric, ribs densely clad in rather long ascending silky hairs. Pappus-hairs up to c.5 mm long, white, slender, very finely barbellate.
Similar taxa
Allied to Celmisia viscosa from which it differs by the scarcely ribbed, smaller leaves (25-50 × 2-6 mm cf. 60-150 × 6-9 mm) which are not or only slightly viscid.
Distribution
Endemic. South Island: Easterly from south Marlborough to Otago
Habitat
Montane to alpine in grassland, fell field and at the base of stable talus and scree slopes
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.

Unknown. Probably best grown from fresh seed and like many Celmisia this species will probably dislike high humidity and drying out

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
angustifolia: From the Latin angustus ‘narrow, constricted’ and folius ‘leaf’, meaning narrow-leaved
