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.

Grassland, forest margins and clearings, coastal sites, scrubland, rock outcrops, riverbeds, pasture, waste places.
A species of lowland to subalpine altitudes favouring dry short tussock grassland communities dominated by Poa cita or more commonly Festuca novae-zelandiae. This aster is also associated with other native and introduced grasses such as Rytidosperma clavatum. Anthoxanthum odoratum and Lachnagrostis sp. and is repeatedly found in grazed pastureland and turfy banks. As an opportunist plant it also frequents other dry open niches such as rock outcrops. scrub, riverbeds. tracks and cuttings. and occasionally turns up as a weed in crevices in paths and roads in urban areas. Plants are not common along the coasts and then restricted to cliff areas.

FACU: Facultative Upland
Occasionally is a hydrophyte but usually occurs in uplands (non-wetlands).
Stoloniferous perennial; stems 1-few, usually ascending, sometimes erect, usually simple, rarely sparingly branched, (2)-5-20-(40) cm tall. Lvs usually mostly basal at flowering; basal lvs short-petiolate, densely white-tomentose on lower surface usually including mid-vein, usually moderately to densely, sometimes sparsely tomentose on upper, plane, narrow- to broad- obovate or oblanceolate, long-cuneate, usually obtuse, sometimes acute, shortly mucronate, (5)-15-40-(60) × (2)-5-12 mm; cauline lvs usually becoming much reduced upwards, often oblong, acute, finally apetiolate and broad-based. Capitula c. 1-2 mm diam., (5)-8-numerous in dense ± globular terminal clusters, very rarely smaller axillary clusters below; longest subtending lvs 0.5-1.5× diam. of cluster. Involucral bracts elliptic to oblong-elliptic, obtuse to subacute, 3.5-4 mm long; stereome green, sometimes tinged reddish purple toward apex; lamina yellow to pale brown or orange; gap and margins usually tinged pinkish purple, sometimes clear. Achenes minutely papillate, c. 0.7 mm long.
E. audax is very similar to E. ruahinicus but is distinguished by the broader, more often obtuse basal leaves, less leafy stems, shorter leaves subtending the terminal inflorescences, and generally paler bract lamina. See E. ruahinicus factsheet for more information. E. japonicus is also similar but differs by having bright green leaves that are sparsely hairy on the surface and have three nerves on the underside.
Pappate cypselae are dispersed by wind and water (Thorsen et al., 2009).
euchiton: From the Greek eu (good) and chiton (tunic or covering)
Fact sheet prepared by Marley Ford (13 December 22). Brief description, Distribution, Habitat, Features, and Similar taxa sections copied from Drury (1972) & Webb et al. (1988).
