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 grey-green shrub inhabiting rocky sites of the southern North Island. Leaves few, 4-8cm long, oblong, with a blunt base joined to the leaf stalk, grey-green, white woolly underneath. Flowers with radiating yellow petals, in loose clusters.
Endemic. Confined to the southern North Island from near Flat Point south to the mouth of the Orongorongo River.
Primarily a coastal species of rock outcrops and bluffs but may extend inland up river gorges and in suitably exposed bluff habitats
Spreading shrub up to approximately 2 m tall, with stout branches. Branchlets and petioles densely clad in soft white tomentum. Leaves rather distant; lamina 40-80 × 25-45 mm, coriaceous, oblong to ovate-oblong, obtuse, rounded to obliquely shallowly cordate at base, entire to shallowly sinuate; upper surface of very young leaves white-tomentose, of mature leaves glabrous and shining except on margins; lower surface densely clad in soft white tomentum, midrib prominent; petiole 15-40 mm long, rather stout, channelled above. Inflorescence of numerous terminal bracted branches; branchlets and pedicels densely glandular-pubescent, bracts foliaceous. Capitula up to 30 mm diameter, in large corymbs; phyllaries 12-16, lanceolate-oblong, acute to subacute, glandular-pubescent on back. Ray-florets approximately 15; ligules bright yellow, broad, spreading, approximately 10 mm long; achenes approximately 1.5 mm long, narrow-oblong, grooved, densely to sparsely scabridulous; pappus-hairs rather scanty, up to 4 mm long, slender, finely barbellate.
B. compacta geographically these species do not overlap.
Pappate achenes are dispersed by wind (Thorsen et al., 2009).
Very easy from fresh seed or semi-hardwood cuttings. Layers readily as well. Will hybridise with most other Brachyglottis, so if pure seed is wanted plant specimens well away from other species in this genus
brachyglottis: Name comes from the Greek words brachus meaning “short” and glottis meaning “the vocal apparatus of the larynx”
Where To Buy
Occasionally offered by specialist native plant nurseries. Most plants sold under this name are hybrids with either B. compacta or B. repanda.
Several hybrid groups of similar looking plants are sold in commercial nurseries under the names Brachyglottis ‘Sunshine’ and B. ‘Otari Cloud’.
