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 drucei Hamlin; Uncinia drucei var. pauciflora Hamlin


Endemic. New Zealand, North, South and Stewart Islands from Mt Hikurangi and Mt Taranaki south.


Alpine. In cushion bog, fellfield, snow banks, seepages and herbfield


Stoloniferous, widely spreading, pale green to reddish-green plants. Stolons c.0.5 mm diameter. Culms 50.0-200.0 × 0.3-1.0 mm, glabrous; basal bracts light brown or straw-coloured. Leaves 5-6(-8) per culm, < culms, 1.0-1.5 mm wide, bright green, soft, the abaxial surface with 3-5 very pale green, raised veins, margins scabrid and tapering towards the narrow, triangular apex. Spikes 05-20 × 3–4 mm, up to 10 mm diam. at maturity, oblong, female flowers 7–18, densely crowded, internodes 0.5-1.5 mm long. Glumes = or > utricles, deciduous, subacute, membranous, pale brown with broad green midrib. Utricles 4–5 × c.1 mm, trigonous, elliptic-lanceolate, dark brown, shining, smooth except for a prominent lateral nerve, widely spreading when ripe, slightly contracted below to a stipe c.1 mm long and above to a beak c.1.5 mm long

Similar Taxa

Close to Carex edura K.A.Ford, which is a very variable species. From Carex edura, C. drucei differs by its widely spreading, stoloniferous rather than tufted or shortly rhizomatous growth habit, usually more numerous, much narrower, grass-like, soft rather than harshly scabrid leaves, and by the shorter, oblong rather than broadly pyramidal spikes with smaller dark-brown rather than green-brown to dark brown glossy utricles


October - January


December - April

Propagation Technique

Unknown. Probably easily cultivated in an alpine house of rock garden, grown from fresh seed and by division of established plants.
