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 conservation 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). 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.

Short-lived perennial or annual herb forming dull green, pink, reddish-green or red clumps; stems 10-50(-200) mm long, sprawling, ± decumbent, suberect to erect, slender, sometimes rooting at nodes in moist conditions, much-branched. Leaves connate at base, 2.0-2.5(-4.0) × 0.5-0.7(-1.0) mm, c.0.7 mm thick, lanceolate or ovate-lanceolate, flattened above, convex beneath; apex acute. Flowers in small cymose clusters in lf axils, not star-like or fragrant, 4-merous, 2-3 mm diameter; pedicels < 1 mm long at anthesis, to c.2 mm long and ± = leaves at fruiting. Calyx lobes c.1.0-1.2 × 0.7-0.8 mm, very broadly ovate, acute to short-acuminate. Petals c.0.8-0.9 × 0.5-0.6 mm, broadly ovate, green or reddish green with pink tips, shortly acuminate, slightly < calyx lobes. Scales c.0.3 mm long, very narrowly spathulate. Follicles smooth. Seed 0.3-0.5 mm long.
August - December

Minute follicles are dispersed by wind and water and possiblty also by attachment (Thorsen et al., 2009).
Easy from fresh seed but very short-lived.
