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 leptostachya Raoul var. scabra (Boott) Hook.f.; Uncinia disticha Col.; Uncinia scabra Boott


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
