| Description: |
Plants usually 25–40 cm tall; stem c. 1.2–1.5 mm in diam. Basal leaves sparsely ciliate, often ±drooping, flaccid, usually to 55 cm long, (1.4–) 3.5–5.0 (–7.8) mm wide; cauline leaves usually 2 (–3), to 30 cm long. Lower bracts 1–2, usually (1.5–) 3–10 (–15) cm long, usually longer or occasionally shorter than inflorescence. Inflorescence rich, composed of
c. 10–35 clusters; clusters mostly pedunculate, ±globular, c. 0.5–0.7 mm in diam.; peduncles straight to ±arcuate, usually 1.1–6.0 cm long, rarely to 14 cm long; secondary branches very frequent. Tepals narrowly lanceolate to lanceolate, acuminate, usually (2.0–) 2.5–3.5 (–4.3) mm long; middle stripe pale castaneous-brown; margins broad, ±membranous to straw-membranous. Anthers (0.7–) 0.9–1.3 (–1.7) mm long; filaments (0.3–) 0.4–0.7 (–0.9) mm long [anther:filament ratio (1.4–) 1.8–3.5 (–5.4)]; style (0.5–) 1.0–1.5 (–1.8) mm long; stigmas (1.5–) 2.0–3.6 mm long. Capsule obovoid, subacute, usually straw-brownish, shorter than perianth; capsule segments 1.8–2.5 × (1.0–) 1.2–1.6 mm. Seeds oblong-ovoid, c. 1.0–1.3 × 0.7–0.9 mm; appendage 0.1–0.2 (–0.3) mm long, ±fibrillate. 2n=12 [AL], fide H.Nordenskiöld, New Zealand J. Bot. 4: 188 (1966). |

| Notes: |
The J.Forster 1775 specimen at BM and some plants from Banks Peninsula (CHR), although very typical in general habit, deviate from the type in short anthers and long filaments, and in shorter style. The nature of this variation remains to be studied. |
