Detailed description
Tufted herb. Leaves (100-150-200(-400) x (5-)10(-20) mm, narrow-linear to lanceolate, tapering from sheath to an acute apex, sulcate, and plicate in cross-section, leathery, upper surface dark green, pellicle thin, often fracturing into irregular shards, leaving leaves with a somewhat silvery green, mottled appearance. Lower leaf surface densely clad in silvery white appressed hairs, midrib distinct and glabrescent. Leaf sheath pale, membranous, 60 mm long, nerves distinct, red or dark red, margins clad in floccose hairs. Inflorescence scape stout, long persistent, 200 mm or more in length, pellicled to floccose (cottony). Capitula 20-40 mm diam., phyllaries 20 mm, linear-subulate, acuminate, ciliate, glabrous on upper surface. Ray-florets white, numerous, 20 mm long. Disk florets yellow, 9 mm, funnelform, teeth narrow-triangular. Achenes narrow-cylindric, grooved, glabrescent 6-7 mm, pappus hairs 8 mm, white, slender, somewhat barbellate.
Similar taxa
The taxonomy of northern lowland Celmisia spp. (all allied to the variable C. gracilenta and C. graminifolia complexes) is in need of revision. Accurate distinction of C. major from its allies is difficult, and currently the treatment offered in Allan (161, Flora of New Zealand Vol. 1) will not adequately distinguish this species from other variants within the complex. Within its range, C. major is the only species which occurs within lowland coastal habitats.
Distribution
Endemic. North Island: West Auckland (Muriwai to Cornwallis (formerly Laingholm), Great Barrier Island (near Fitzroy – apparently extinct), Kaikoura Island, Aiguilles Island.
Habitat
Strictly coastal, on rock headlands, cliff faces, and islets, where it usually grows in low turf on peaty or silty soils with Disphyma, Tetragonia and Samolus. Occasionally found in coastal shrublands.
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.

Threats
Habitat loss through the encroachment of taller and faster growing weeds, and coastal erosion. Several accessible populations have been damaged by trampling through human traffic to access popular viewing sites on headlands and near shore islets. Some sites have vanished altogether through, it would seem, overcollecting. Apparently always scarce on Great Barrier Island, this daisy now only persists in that island group in a single site on a very remote northerly location.

Taxonomic notes
Field work and herbarium evidence suggests that C. major is more closely linked to C. adamsii var. rugulosa, which in turn seems to be a later heterotypic synonym for C. graminifolia Hook.f., itself a much misunderstood species. The status of C. major var. brevis, an Mt Egmont endemic is not clear, it is certainly not close to var. major. Further critical study into this matter is urgently needed.

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
