Conservation status of New Zealand indigenous vascular plants, 2012
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2012 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2009 and replaces all previous NZTCS lists for vascular plants. Authors: Peter J. de Lange, Jeremy R. Rolfe, Paul D.

NVS Species Code

BRAPER

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.

Synonyms

Senecio perdicioides Hook.f., Senecio multinerve Colenso, Senecio distinctus Colenso, Senecio perdicioides var. distinctus (Colenso) Kirk., Brachyglottis perdicioides var. distincta (Colenso) B.Nord., Senecio tripetaloides Colenso

Distribution

Endemic

. New Zealand: North Island, where it is found in scattered sites from East Cape (Hicks Bay) to Mahia Peninsula.

Habitat

Coastal shrubland and forest - usually in open ground. Often forming cohorts within scrub.

Features

Aromatic shrub 1-2 x 1 m. trunk stout, bark pale to dark grey, peeling in small stringy flakes or shards. Branchlets numerous, spreading, slender and "twiggy" . Leaf buds resinous and sticky, finely covered in "cobb webbed" hairs. Petioles slender, 10-15 mm long. Leaves (10-)25-50(-70) x (15-)20(-25) mm, oblong

to elliptic-oblong, finely crenate-serrate, dark green, to yellow-green with paler undersides, glabrescent with undersides usually covered in sparse "cobb webbed" hairs. Inflorescence a crowded corymb. Captitula (5-)12-20(-30), turbinate, borne on pubescent, somewhat resinous and sticky pedicels. Ray-florets 1-3(-5), ligules oblong, yellow, 6-8 mm, apex sometimes bidentate. Phyllaries oblong, pale grey green, with a pubescent midrib, margins scarious. Seed a cypsela, pubescent or glabrescent, 2-2.5 mm, pappus-hairs stiff, 5 mm, finely barbellate.

Similar Taxa

Brachyglottis pentacopa, which differs by the more numerous ray

-florets (usually 5), and smaller, rounder leaves. However, there is some indication that these species intergrade, with some of the more southerly populations of B. perdicioides very similar to B. pentacopa. Accordingly some botanists informally treat B. pentacopa as a variety or subspecies of B. perdicioides, while others regard it as an absolute synonym. Further research into the matter is required.

Flowering

(October-) November-April (-May)

Flower Colours

Yellow

Fruiting

(December-) January-April (-May)

Propagation Technique

Easy from fresh seed and semi-hardwood cuttings

. A very hardy shrub which is tolerant of a wide range of habitats, soils types and moisture regimes.

Threats

Habitat loss appears to be main threat. However, recruitment appears limitng in some sites, possibly as a consequence of weeds which now often form a permnant ground cover in the places where seedlings would normally germinate. Established plants do not appear to be browsed by livestock, thus mature plants can persist in rough pasture.
