Detailed description
Woody-based perennial herb arising from a multicipital stock. Leaf lamina linear, rigid but recurved, 50-150 × 3-5 mm; upper surface grooved, dark green, clad in a thick pellicle which becomes golden on drying; lower surface clad in thick appressed white tomentum, midrib prominent; margins entire, often revolute. Sheath 30-60 mm long, membranous, yellow-orange and clad in a thin pellicle. Scape 100-150 mm × 2-3 mm, bracts few. Involucral bracts erect, linear-oblong to subulate, acute, up to 12 mm long, inner narrower than outer; margins fringed with long white hairs, particularly near the base; surface almost glabrous; venation simple. Receptacle obconic, upper surface alveolate. Ray florets up to 20 mm long, limb linear and glabrous, tube narrow with a few eglandular hairs near top. In disc florets, corolla tube gradually narrowed from apex to base, glabrous or sparsely hairy with long biseriate hairs; stamen tip acute, anther tails short; style bifid, the arms differentiated into a lower parallel-sided papillose portion and an upper short-triangular portion bearing short collecting hairs. Pappus bristles unequal, up to 4 mm long, with closely spaced short teeth. Achene 2.0-3.0 × 0.5 mm, fusiform, compressed, strongly ribbed and clad in bifid hairs.
Similar taxa
Could be confused with Celmisia insignis a Marlborough endemic from which it differs its smaller achenes that are covered in bifid hairs rather than glabrous, by its shorter pappus, by the disc florets which have fewer corolla hairs and by its shorter, darker green and more distinctly grooved leaves. In addition, Celmisia insignis lacks the distinctive pellicle characterising dried specimens of C. vespertina. The species is similar to C. petriei and C. polyvena from both of which it differs by its intermediate size and leaf and by its distinctive pellicle and sheath colour.
Distribution
Endemic. South Island: Mostly west of the Main Divide of the Southern Alps, from near the Taramakau Valley southwards to near Mount Aspiring. Otherwise known in the east only from the Ben Ohau Range
Habitat
Alpine grassland and associated fell 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.

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
