Detailed description
Much-branched shrub up to 1 m tall. Final branchlets compactly arranged, tomentose, produced into slender peduncles with foliaceous bracts bearing solitary to racemed (rarely > 3) capitula on slender bracted glandular-pubescent pedicels, usually so massed as to produce a pseudo-corymb. Leaves close-set, coriaceous; lamina 20-50 x 5-15 mm, narrow to obovate-oblong, obtuse, narrowed into slender tomentose channelled petiole up to 20 mm long; margins distinctly crenate and usually waved; glabrous brownish green above, below clad in closely appressed white tomentum; midrib usually distinct. Capitula up to 20 mm diameter; phyllaries linear to linear-spathulate, acute, glandular-pubescent on back, inner with scarious tips. Ray-florets 10-15; ligules yellow, broad, spreading to recurved. Achenes 3.5 mm long, compressed, finely grooved, hispidulous; pappus-hairs slender, up to 6 mm long, very finely barbellate.

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.
