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.

Indigenous. New Zealand: Kermadec (Raoul Island), Three Kings, North, South, Stewart, and Chatham Islands. Also south-east Asia, New Guinea, New Caledonia and Australis (one record Queensland - Chinnock 1998).
Coastal to montane. In gumland scrub, shrublands, forest margins (and along open ridgelines in dense forest), and on roadside banks and cuttings.
Wetland plant indicator status rating
Information derived from the revised national wetland plant list prepared to assist councils in delineating and monitoring wetlands (Clarkson et al., 2021 Manaaki Whenua – Landcare Research Contract Report LC3975 for Hawke’s Bay Regional Council). The national plant list categorises plants by the extent to which they are found in wetlands and not ‘drylands’. The indicator status ratings are OBL (obligate wetland), FACW (facultative wetland), FAC (facultative), FACU (facultative upland), and UPL (obligate upland).
FACU: Facultative Upland
Occasionally is a hydrophyte but usually occurs in uplands (non-wetlands).
Main stems scrambling or climbing (scandent) up to 8 m long, wiry, much-branched, terete, with scattered appressed subpeltate attenuated scale leaves, 3.5-5.0 mm long. Branchlets scattered, spreading, flattened into 1 plane. Leaves trimorphic, yellow-green (very rarely orange); lateral leaves in 2 alternate to opposite rows, tending to curl downwards, 3-5 mm long, up to 1 mm wide, ovate-lanceolate, falcate, attenuate, adnate; upper leaves in 2 alternate to opposite rows, appressed, 1-2 mm long, c.0.2 mm wide, scale-like; lower leaves in 1 row, very scattered, appressed, up t0 1 mm long, scale-like, obscure. Strobili up to 80 mm long, yellow-brown, straight or sometimes forked, borne in large pendulous clusters on sparsely-leaved much-branched stalks. Description adapted from Chinnock (1998) and Brownsey & Smith-Dodsworth (2000).
Easily distinguished from all other New Zealand representatives of the family by the scrambling, climbing growth habit, flattened leaves, and by the numerous, clustered, pendulous strobili. For distinctions from Diphasium scariosum see under that species.
Difficult. Should not be removed from the wild.
volubile: Twining; from the Latin volvere; a twining growth habit
