Detailed description
Small shrub or subshrub with rather stout procumbent to ascending branched woody stems up to c.20 mm long; branchlets stiff, rather close-set, more or less 50 mm long. Leaves densely imbricate, erect, finally reflexed. Lamina c.5.0-10.0 × 1.5-2.0 mm, linear-oblong to subulate, coriaceous; upper surface glabrous or nearly so, pale green; lower surface densely clad in soft white tomentum obscuring midrib; margins strongly revolute, studded with minute papillae (these mingled with a few rather stout hairs); apex obtuse, more or less trigonous-cucullate; base passing into broad pale membranous glabrous sheath more or less = lamina, with distinct midrib. Scape c.50 mm long, slender, densely glandular-pubescent; bracts few, distinctly widened toward base, more or less 5 mm long, linear. Capitula 20-25 mm diameter; involucral bracts c.5 mm long, linear-oblong, acute to subacute, densely glandular-pubescent. Ray-florets linear oblong, 15 mm or longer, 2 mm broad, obtuse, thickened and incurved at the tip, disk-florets narrow-tubular, c.5 mm long. Achenes c.3-4 mm long, narrow-cylindric, obscurely ribbed, with a few hairs. Pappus-hairs fine, white to sordid-white, up to c.4 mm long, very minutely barbellate
Similar taxa
One of a small group of subshrub Celmisia which includes C. brevifolia, C. gibbsii, C. rupestris, C. lateralis and C. walkeri. From these species C. ramulosa is distinguished by the scape which is 100-400 mm long; by the lamina which is 5.0-10.0 x 1.5-2.0 mm, and by the leaf undersides which is clad in soft white tomentum. Celmisia ramulosa var. tuberculata differs from var. ramulosa by the leaf margin which is distinctly papillate-hairy rather than entire and glabrous
Distribution
Endemic. South Island: Central Otago (mainly in the east)
Habitat
Upper montane to subalpine rocky places and fellfield
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.

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
