The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

Current conservation status
The conservation 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). 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.

Endemic. South Island: Central Otago (Rock and Pillar Range)
Alpine. Inhabiting snowbanks and hollows above 1200 m.
Perennial rosette herb, often forming loose mats. Leaves apetiolate, narrow- spathulate, mostly entire, rarely with 1-2 pairs of shallow teeth near apex, obtuse, glabrous, 5.0-10.0 × 1.0-1.5 mm. Peduncle naked, glabrous except for few glandular hairs below capitulum, 30-45 mm long and 0.3-0.6 mm diameter at flowering, elongating to up to 70 mm at fruiting. Involucral bracts elliptic to narrow-oblong, obtuse and fimbriate to apex, glabrous except for few glandular hairs at base, 2.5-3.0 mm long. Rays 12-22, white, c.3-5 mm long. Disc yellow. Achenes obovoid-oblong, compressed, eglandular, c.1.5 mm long; pappus of bristles c.0.3 mm long
Perhaps most similar to B. linearis - which is a species of marginal turf communities around lakes Te Anau, Manapouri and the Mavora Lakes. From that species it differs by its ecology (alpine in snow banks and hollows), larger flowers on longer scapes, hairy capitula and achenes, and longer ray florets.
December – February
January - April
Pappate cypselae are dispersed by wind (Thorsen et al., 2009).
Difficult. Should not be removed from the wild.
Unclear. Probably a Naturally Uncommon species however this species remains very poorly known and until a comprehensive survey is undertaken ascertaining the exact conservation status of this species remains guesswork. It for this reason that it has been listed as Data Deficient. Furthermore, the status of similar plants found on the ultramafics of West Dome and the Livingston Range needs investigation
brachyscome: From Greek brachys ‘short’ and comus ‘hair’, refers to the lack of papys on the fruit
humilis: Lowest, dwarf, small, slight
