The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

Current conservation status
The threat classification status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS) – more information about this can be found on the NZTCS website This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley. Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – a suggested threat classification status has not been assessed by the NZTCS panel.

Alpine (1300-1600 m a.s.l.). On skeletal soils and associated peat within rocky herbfield.
Woody-based herb with short branchlets arising from a sparsely multicipital stock, usually just below the soil surface; living leaves in rosettes at the tips several rosettes. Leaf sheaths densely imbricate and compacted into a pseudostem. Leaf lamina 40-120 × 20-50 mm, coriaceous, at first erect but later decumbent, cordate to ovate; upper surface often sulcate, concolorous, yellowish to glaucous-green, glabrous or with scattered white hairs when young; lower surface thickly clad in felted, dull, deep buff to dark chocolate brown hairs: tip acute; margins entire, slightly to moderately recurved, often with a rim of ferrugineous hairs; base prominently cordate; petiole up to twice lamina length, purple, covered in floccose ferrugineous hairs. Scape purple, clad in dense ferrugineous tomentum, up to 350 mm long; bracts numerous, erect, linear, monocephalous. Capitula up to 60 mm diameter. Phyllaries in several series, linear-subulate, erect, glabrous in lower part and densely brown-tomentose towards tip. Ray florets c. 25, ligulate, the limb linear-lanceolate, white. Disc florets c. 110, funneliform, yellow; tube with eglandular biseriate hairs. Achene fusiform cylindric, ribbed, 4-5 mm long, glabrous. Pappus unequal, 5-6 mm long, of 25-30 bristles.
Could be confused with Celmisia traversii which is common south of the Wairau River. From that species Celmisia cordatifolia differs by its shorter leaves which are distinctly cordate, and yellowish- or glaucous-green rather than bright green. Celmisia cordatifolia var. similis, a doubtfully distinct taxon differs from var. cordatifolia by its thinner and more pointed leaves whose lamina margins are prominently rather than weakly recurved, and by the tomentum of lower surface which is closely appressed, lustrous, and coloured pale buff rather than rather thickly felted, dull, and coloured deep buff to chocolate brown. Celmisia cordatifolia var. similis is known only from a few gatherings all made from Mt Richmond in the Wairau Mountains. Celmisia cordatifolia var. brockettii differs by the lanceolate-cordate rather than cordate-ovate leaf. Very little is known about var. brockettii which was not regarded as distinct by Given (1984) but seems every bit as distinctive as var. similis which he did accept.
October - January
December - April
Pappate cypselae are dispersed by wind (Thorsen et al., 2009).
Unknown. Probably easy from fresh seed that has been cold treated. However, like many Celmisia probably difficult to maintain in warm or humid climates.
A Naturally Uncommon, narrow range endemic which though extremely localised is common in its few known localities and under no obvious human induced threats.
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
