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.

Endemic. New Zealand. North Island from Great Barrier Island and the Kaipara south (most common in the east). South Island (Nelson and thence east of the main divide to about Dunedin).
Coastal to subalpine. Usually in dense lowland to montane forest. However, also locally common in dune forest and scrub in the northern part of its range.
Rather harsh-textured, rigidly erect, densely tufted, yellow-green, olive-green or dull bluish green plants. Culms 250-900 mm tall, usually < 1 mm diameter, erect, strongly scabrid towards the top; basal sheaths dark brown. Leaves 3-6 per culm, > or = culm, 2-3 mm wide, narrow-linear, moderately scabrid on margins and on upper surface along midvein, tips subacute in shorter leaves, more tapering and filiform in longer leaves. Spikes 30-100 long, bracteate, lowermost glume often broad and leaf-like, much > spike, or the midrib greatly extended forming a long filiform awn, female flowers c.10, lax, internodes to 8 mm long at base of spike, 2-4 mm long above. Glumes < or = utricles, persistent, obtuse or lowermost subacute, membranous, very light brown, the midrib of lower glumes often scabrid. Utricles 4.5-6.0 × c.1 mm, plano-convex or subtrigonous, grey-brown, scabrid on both surfaces towards the apex, narrowed above to a beak 1 mm long and scarcely narrowed below to a greenish stipe 1.0-1.5 mm long
October - November
November - March (- June)
Easily grown from fresh seed and by division of established plants. Can be grown in a wide variety of soils from free-draining to permanently moist - but resents water logging. Best in semi-shade.
carex: Latin name for a species of sedge, now applied to the whole group.
