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



C. druceana Hamlin var. druceana


Endemic. North Island, Ruahine Ranges. South Island, north west Nelson.


Sub alpine to alpine sedge of damp ground in tussock grassland.


Light reddish green tufted sedge 10- 20 cm tall. Culms smooth, circular in cross-section (terete), 0.5-1 mm diameter. Basal sheaths grey-brown or light brown,. Leaves > culms, up to 35 cm long, (1-)1.5(-2.2) mm wide, flat, concave or convex, red, margins scabrid (with teeth), tip curled. Inflorescence of 4-6 unstalked, closely-packed, 0.5-1(-1.5) cm × 3-5 mm, ovate or cylindrical spikes. Male spikes at the base, female at the top. Glumes = or < utricles (fruits), broadly ovate or oblong, pale brown with red markings, apex cleft, with the green midrib extending as a scabrid 2 mm long awn. Utricles c.2.5 × 1.3-1.5 mm, ovoid to rhomboid, 3-angled (trigonous) or irregularly inflated, yellowish with red near tip, beak minute (0.3 mm), black or dark brown. Stigmas 3. Nut c. 1 × 1 mm, elliptic-obovoid, 3-angled, cream to dark brown.

Similar Taxa

Allied to C. astonii (which is treated as a variety of C. druceana in Flora 2) from which it is distinguished by its wider leaves ((1-)1.5(-2.2) mm vs. 0.7-1.2 mm in C. astonii)), clustered rather than distant spikelets, and by its longer awns ( up to 2 mm, those of C. astonii up to 0.5 mm). C. astonii is confined to the Kaimanawa and Ruahine Ranges, while C. druceana extends to north west Nelson.
