NVS code
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) – 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.
Please note, threat classifications are often suggested by authors when publications fall between NZTCS assessment periods – an interim threat classification status has not been assessed by the NZTCS panel.

Habitat
Ravines and stream-sides.
Detailed description
Sparingly branched shrub up to 4 m. tall with black bark; branches slender, thinly tomentose when young. Leaves membranous, becoming glabrous above, clad below in thin appressed silvery tomentum; lamina 7–18 cm long, oblong- to elliptic-lanceolate, acute to acuminate, obliquely subcordate at base, sharply and coarsely doubly dentate; petiole 2–5 cm. long. Capitula approximately 1 cm diameter, numerous, in large terminal panicles, on slender pedicels densely clad in dark glandular hairs. Phyllaries approximately 8, linear-oblong, obtuse, scarious, glabrous; ray-florets 4–6, ligules approximately 3–4 mm long, broad, white. Achenes approximately 1.5 mm long, compressed, grooved, hispido-papillose; pappus-hairs up to 5 mm long, stiff, barbellate.
Flowering
November–January
Flower colours
White
Fruiting
December–March
Life cycle
Pappate achenes are dispersed by wind (Thorsen et al., 2009).
Etymology
brachyglottis: Name comes from the Greek words brachus meaning “short” and glottis meaning “the vocal apparatus of the larynx”
