Simplicia laxa Kirk (fide Zotov 1971)

Key to New Zealand Simplicia

1	Plants tufted; culms erect, up to 1 m tall (culm nodes not root-forming); inflorescences erect, linear, branches, erect, appressed to rachis, bearing spikelets almost to base	Simplicia buchananii
-	Plants decumbent; culms weakly ascendant, rooting freely from culm-nodes so forming diffuse interconnected widely sprawling clonal patches 0.6-1.0 m diameter; inflorescences linear to pyramidal, binate, basal branch or branches reflexed, devoid of spikelets from lower ½ to ⅔	3
2	Mid-stem and upper stem leaf sheaths finely ribbed, copiously hairy (hairs 0.35-0.40 mm long); adaxial leaf-blade ribs hairy; inflorescence branches antrorsely hairy, pedicels 1.00-1.06 mm long; lemma pubescent	Simplicia laxa
-	Mid-stem and upper stem leaf sheaths strongly ribbed, ± glabrous (occasionally bearing minute hairs towards sheath apex); adaxial leaf-blade ribs smooth or finely scabrid; inflorescence branches scabrid, pedicels 0.20-0.30 mm long; lemma minutely scabrid	Simplicia felix
