Detailed description
Stock and bases of petioles clad in long pale buff hairs. Leaves: lamina 30–150 × 20–60 mm, oblong to broad-oblong or suborbicular, obtuse, cordate to truncate at base, sub-membranous, clad when young on both surfaces in dense white sub-appressed tomentum, sometimes becoming nearly glabrous above when mature. Petioles 30–150 mm long, clad in dense soft white tomentum, finally nearly, glabrous. Scapes up to 350 mm long, usually slenderly branched above, clad in dense tomentum of soft whitish hairs mingled with glandular ones, becoming nearly glabrous with age; lower bracts spathulate, floral bracts linear. Capitula 20–40 mm diameter, ligules yellow, up to 20 mm long; phyllaries tomentose on back, linear, obtuse. Pappus-hairs up to 5 mm long, barbellate. Achenes approximately 4 mm long, linear.
Distribution
New Zealand: Endemic. South Island (mostly east of the Main Divide from Arthur’s Pass to the Blue Mountains).
Habitat
Lowland to subalpine grassland.
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.

Taxonomic notes
Cheeseman (Man. N.Z. Fl. 1906, 368) remarked of the genus in New Zealand: “The herbaceous species are exceedingly variable, and some of them difficult to determine; but the shrubby varieties are remarkably distinct.” The complex of forms found in the herbs with leaves in rosettes and scapose inflorescences is still far from resolved, especially as to how far the linking forms are due to hybridism and how far to true-breeding varieties. There is good evidence that hybrids occur of the origins B. haastii × B. southlandica. It is probable that detailed study of the occurrences of glandular hairs and of trichomes would yield evidence of “introgression”, as Wall’s examination of the populations on Banks Peninsula (T.N.Z.I. 50, 1918, 198) suggests.
