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 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.

Rare small sparse shrub inhabiting shaded streams of the northern North Island. Leaves thin, longer than wide, base of leaf indented, margin with large sharp teeth and a sharp tip, underneath purpleish-white and veins are obvious. Flowers small, white, in inconspicuous sprays.
Endemic. North Island - Coromandel, Hunua Ranges, Eastern Northland
Ravines and stream-sides.
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.
November – January
December - March
Pappate achenes are dispersed by wind (Thorsen et al., 2009).
brachyglottis: Name comes from the Greek words brachus meaning “short” and glottis meaning “the vocal apparatus of the larynx”
