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.

Endemic. South Island: Vicinity of Ngakawau (Ngakawau River Gorge, Haggard Creek, Blackwater River)
Lowland to montane. Riparia, in damp seepages and wet spots in rock talus above rivers and creeks, and on shaded, wet cliff faces along river gorges
Woody-based herb with branchlets arising from a multicipital stock, usually close to soil surface; living leaves in large rosettes at the tips of branchlets, the whole plant forming irregular patches of numerous rosettes; leaf sheaths densely imbricate and compacted, forming a pseudo-stem. Leaf lamina 150-350 × 18-30 mm, subcoriaceous or flaccid, older leaves weakly patent, lanceolate to oblong; upper surface finely sulcate, concolorous, dark green, glabrate or with a thin, scurfy greenish pellicle; lower surface densely covered in glistening appressed tomentum, midrib prominent and sometimes purple; tip acute; margins entire, slightly revolute; base ± gradually narrowed to a purple, ribbed petiole up to 80 mm long. Sheath up to 60 × 25 mm, purple (rarely greenish), clad in floccose, white hairs or glabrate. Scape purple, thinly clad in floccose, white hairs, slender, up to 300 mm long; bracts several in upper ½, erect, linear; monocephalous. Ray florets c.40, ligulate, the limb narrow-linear, white. Disc florets c.50, 6 mm long, funneliform, yellow, tube with long eglandular biseriate hairs. Achene fusiform, grooved, 3.0-4.5 mm long, glabrous or slightly hairy; hairs short, appressed, bifid. Pappus unequal, c.6 mm long, of c.30 barbellate bristles.
Celmisia morganii is allied to Celmisia dubia, C. monroi, and C. semicordata. From these species it is most likely to be confused with C. monroi from which it differs by the floppy rather than erect growth habit, leaves whose lamina is glabrate or with a scurfy, greenish rather than leaden pellicle.
September - July
October - August
Easily grown in a shaded site, planted within a permanently moist, free draining, soil. Dislikes humidity and will not tolerate drying out. Best grown from fresh seed which should be sown immediately or stratified in a fridge or freezer for 1-3 months
A Naturally Uncommon, narrow range endemic that is abundant within its few known locations. Although there are known major active threats the main population is located within a river system under investigation for a hydroelectric dam
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
Where To Buy
Occasionally available from specialist native plant nurseries.
Notes on taxonomy
Celmisia morganii is considered by some New Zealand botanists as indistinct being in their view simply a westerly outlier of C. monroi
