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.

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.

Structural Class

Monocotyledonous Herbs

Synonyms

Triglochin flaccidum A.Cunn., Triglochin striatum Ruiz et Pav.

Distribution

Indigenous to New Zealand. Three Kings, North, South, Stewart, and Chatham Islands. Also present in South America, America, Africa, Australia and south Portugal.

Habitat

Mainly coastal in damp muddy ground, salt marsh, estuaries, and damp seepages on coastal cliffs, boulder beaches and within damp coastal turf. Also found inland around lake margins (in marginal turf communities) and in other suitable damp places. Sometimes even in tall forest.

Features

Fleshy, grass-like tufted or sward forming perennial herb. Bases not bulbous, roots distinctly fibrous. Leaves 10-400x 0.3-2.0 mm, dark green, reddish green or brown-green, ligule rounded to subacute; lamina linear, linear-filiform, flattened toward subacute apex. Inflorescence racemose, 10-200 mm long; pedicels 1-3 mm long, set at a rather wide angle to axis. Flowers(1-)2 mm long; stylar apices green or reddish-green, slightly spreading. fruit 2-3 mm long, dark green, reddish green to brown, subglobose, comprising 3 keeled fertile follicles and 3 narrower sterile carpels, all rather loosely attached to carpophore.

Similar Taxa

Triglochin palustris L. is superficially similar. However, this is a taller (up to 800 mm), bulbous, plant with narrow-linear fruits with follicles that are not keeled and narrow to an acutely pointed base, and which separate from the base first, splitting widely such that they resemble a small arrow head. The leaves are distinctly semi cylindric rather than flattened toward their apices.
