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.

Brief description
Poorly known small bushy subalpine shrub. Leaves leathery, tapering to a narrow tip, dark green with a white margin and white furry underneath. Flowers in loose clusters at tips of twigs, white furry body with an orange tip.
Distribution
Endemic. South and Stewart Islands (possibly an Outlier on Mount Taranaki, North Island as described by Armstrong 1879). Most of South Island, commonly west of main divide.
Habitat
Lowland to higher montane forest and scrub.
Features
Compactly branched shrub up to 3 m tall. Branchlets ribbed, clad as are inflorescence-branchlets in appressed whitish tomentum. Leaves 50-100 × 30-50 mm, on grooved petioles up to 50 mm long, elliptic, narrowed towards apex and base, subcoriaceous, glabrous and shining above, veins evident; below clad in appressed silvery-white to greyish tomentum, midrib rather prominent. Panicle up to 250 mm long, laxly branched, lower bracts foliaceous; pedicels up to 20 mm long, woolly-tomentose. Capitula campanulate, up to 10 mm diameter, discoid; phyllaries linear-oblong, subcoriaceous, subacute to obtuse, woolly-tomentose on back. Female flower up to 5, disk-florets numerous. Achenes 2.5-3 mm long, striate, rough-pubescent; pappus-hairs 3-5 mm long, finely barbellate.
Similar taxa
Similar to B. elaeagnifolia, which has leaves that are a different shape (obovate to lanceolate-oblong, obtuse); more compact inflorescence panicle (sub-pyramidal to sub-racemose), which is usually smaller (150 mm).
