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


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




Indigenous. New Zealand: South and Stewart Islands. Also in New Guinea and Tasmania.


In the South Island strictly montane to alpine., in bogs. On Stewart Island in similar sites but at lower altitudes as well as alpine.


Compact, dark brown, occasionally glaucescent herb forming cushions up to 900 mm across. Roots fibrous. Stems 20–80 mm long, erect, wiry. Leaves 5–20 mm long, << 0.5 mm wide, distichous, very stiff erect to erecto-patent, glabrous, linear-setaceous, tapering to a long acicular tip; sheath almost = lamina in length, glabrous, lustrous, brown, produced at the tip into a ligule. Flowering stems > leaves, naked, terminated by 2–3 alternate glume-like, minutely papillate bracts; each bract enclosing 1 pseudanthium only, the third or uppermost bract sterile; hyaline scales 0. Male 2 in each pseudanthium. Female, 2 in each pseudanthium, styles not connate; occasionally with one ovary aborting. Fruit slightly > 0.5 mm. long, oblong-ovoid, surface faintly and irregularly reticulate

Similar Taxa

Distinguished from Centrolepis Labill. by have two male flowers per pseudanthium; two fused and collateral female flowers; two-three, distinctly alternate, glume-like floral bracts and opaque, light-brown leaf-sheaths.
