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



Uncinia clavata (Kük.) Hamlin; Uncinia australis Pers. var. clavata Kük.; Uncinia uncinata (Linn.f.) Kük. var, clavata (Kük.) Kük.


Endemic. New Zealand: North and South Islands, from about the Hunua Ranges south


A species of montane forest, scrub and on river flats


Robust, dark green to yellow-green plants. Leaves 5–9 per culm, usually > culms, 4-6(-8) mm wide, strongly scabrid on the margins and on the adaxial surface towards tip. Spikes 50-140 mm long, usually bracteate, clavate, 7-10(-15) mm diameter at the top below the male spike, female flowers numerous, usually c. 65-100, very closely crowded throughout almost the whole spike, internodes 0.5-4.0mm long but up to 8 mm long at base of spike. Glumes =, > or rarely < utricles, deciduous, narrow-lanceolate, acute or acuminate, coriaceous or subcoriaceous, yellowish brown to dark brown, midrib green. Utricles 5.0-7.0 × 1.5-2.0 mm, plano-convex to subtrigonous, ovate, yellow-brown to dark brown when ripe, one to two lateral nerves prominent and lighter coloured, stipe 1.5-2.0 mm long, beak 1.5-2.0 mm long; spreading widely when ripe.

Similar Taxa

Most closely allied to Carex megalepis K.A.Fordand C. uncinata L.f. Of both species it is most closely allied to Carex megalepis from which it differs by the yellow or dark brown rather than golden yellow or rust-coloured glumes which are equal to or only slightly greater in length (rather than twice as long) than the utricles, and by the widely rather than scarcely spreading utricles. Carex uncinata differs by the usually narrower spikes, early deciduous rather than longer lasting deciduous glumes, which are usually much shorter than the utricles


October - December


November - April

Propagation Technique

Easily grown from fresh seed and by the division of established plants (though these may then take a while to settle). Prefers a shaded site, and should be planted within a deep, rich, free draining but permanently moist soil
