Detailed description
Small stout closely branched shrub up to 60 cm tall. Main branches decumbent at base, ascending; upper branches approximately 10 mm diameter, with pale bark; final branchlets approximately 2.5 mm. diameter, invested with remains of leaf-bases. Leaves very close-set, 20-25 × 1.5-2 mm.

Capitula approximately 30 mm diameter, solitary, terminal on arrested branchlets up to 10 cm long, and bearing numerous leaflike bracts up to 15 × 1 mm Phyllaries approximately 12, approximately 10 mm long; closely subtended by bracts overtopping capitulum in bud; softly tomentose on back, with broad scarious margins. Ray-florets yellow, spreading, approximately 15 mm long, broad-oblong, clawed; achenes 1.5 mm. long, linear-oblong, glabrous, obscurely ribbed; pappus-hairs up to 4.5 mm. long, rather rigid, strongly 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.
