Vascular – Native
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.

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.

Wetland plant indicator status rating
Commonly occurs as either a hydrophyte or non-hydrophyte (non-wetlands).
Light bluish green or rarely pale yellow-green perennial tufts, 25-650 mm, with stiff culms and leaves, or with finer and less rigid leaves; branching intravaginal. Leaf-sheaths smooth, submembranous to subcoriaceous, ± distinctly nerved, light brownish to purplish; ligule 0.7-2.0 mm, smooth, rounded to truncate, or ± tapered at centre and acute; leaf-blades 10-120 mm, involute, c.0.5 mm diameter in rolled state, rigid and erect, or finer and softer, abaxially smooth, adaxially sparsely scabrous on nerves, or sometimes densely scabrous throughout, margins scabrous, narrowed to a fine acute tip. Culms 20-400 mm, enclosed by uppermost leaf-sheaths at flowering, later visible, smooth, erect. Panicle 20-200 × 2-55 mm, at first narrow-linear, racemose above, with few, erect, usually scabrous branches below, later more open with ± spreading branches bare at base. Spikelets 3.5-10.5 mm, 2-10-flowered, narrow, almost terete, light green to purplish. Glumes often quite unequal, elliptic-oblong, margins and sometimes midnerve minutely ciliate near tip; lower glume 0.6-2.3 mm, 1-nerved, subacute to subobtuse; upper glume 1.3-3.5 mm, 3-nerved, subobtuse to obtuse. Lemma 2-4 mm, 5-nerved, broad-elliptic, with very minute hairs at base not usually visible at ×10, and occasionally a few minute hairs on nerves near base, midnerve usually not quite reaching finely ciliate, obtuse tip. Palea slightly < lemma, bifid, keels scabrous in upper 2/3. Rachilla 0.5-1.0 mm. Anthers 0.4-1.0 mm. Seed 1.0-1.8 × 0.4-0.7 mm.

Distinguished from other Puccinellia by the intravaginal new shoots; involute leaves; panicle overtopping leaves; upper glume usually 2.0-3.5 mm; lemma with minute hairs near base visible only at high magnification (c.×40); palea keels finely scabrous. Differentiating between Puccinellia stricta and Puccinellia walkeri (which sometime co-occur) can be difficult: the size of the lemma (3-5mm in P. walkeri, usually less or = 3mm in P. stricta) is a good guide. The panicle of P. stricta also tends to open out post-flowering so that obvious branches are visible rather than remaining closely and erectly branched. The palea keel in P. stricta is scabrid but is ciliate in P. walkeri (though, this difference can be small).
September - December
October - March
Easily grown from seed and by division of established plants.
Not Threatened but uncommon north of the Waikato.
puccinellia: After the italian botanist Benedetto Puccinelli (1808 - 1850).
stricta: From the Latin strictus ‘upright, stiff’
