Perennials (5–) 9–20 (–28) cm long, densely hairy, densely caespi<strong>to</strong>se; rhizome short,<br />
vertical, ±many-headed; s<strong>to</strong>lons absent. Basal leaves short, usually 3–6 cm long, (1–) 2–3 mm<br />

<strong>to</strong>mentum; cauline leaves absent or 1 (–2), with blade reduced, filiform, 1–2 cm long; sheath<br />
<strong>to</strong> 2 cm long. All leaves with subulate acute tip; margins ±smooth. Lower bract ovate, strawbrown,<br />
membranous, c. 5 mm long, similar <strong>to</strong> middle bracts. Inflorescence erect, cylindrical<br />
<strong>to</strong> ±ovoid, densely congested, spike-like, usually 0.8–2.0 × 0.6–1.0 cm, of 1–5 few-flowered<br />
clusters. Bracteoles ovate, scarious, 1.5–2.0 mm long, ciliate near apex. Tepals ±entire,<br />
subequal, rarely ±denticulate near apex, (1.3–) 1.6–1.9 (–2.1) mm long, acuminate; lower<br />
middle part dark castaneous brown; margins broad, white-scarious. Stamens 3 (4–6); anthers<br />
0.4–0.5 (–0.7) mm long; filaments 0.3–0.5 mm long; style c. 0.3 mm long; stigmas c. 0.5 mm<br />
long. Capsule obovoid, equalling or slightly exceeding perianth, ±obtuse <strong>to</strong> subacute, dark<br />
brown <strong>to</strong> black; capsule segments 1.5–2.0 × c. 1.1–1.3 mm. Seeds pale castaneous, 0.8–0.9 mm<br />
long, c. 0.6 mm wide; appendage minute, appearing as a paler basal fibrillate swelling <strong>to</strong><br />

Perennials 10–40 cm tall, densely caespi<strong>to</strong>se; rhizome short; s<strong>to</strong>lons absent. Leaves with<br />
±acicular tip and sparsely ciliate, with ±smooth margins. Lower bract herbaceous, exceeding<br />
inflorescence, 3–5 cm long. Inflorescence ±nodding, of (1–) 3–9 clusters congested in<strong>to</strong> a lobate<br />
or pyramidal head up <strong>to</strong> 2–3 × 1.5 cm. Bracteoles ovate, entirely membranous, often castaneous<br />
at base, 1.5–2.0 mm long, ±entire or sparsely ciliate near apex. Tepals subequal, ±entire,<br />
usually with a dark castaneous brown midrib and broad whitish-membranous margins. Style<br />
0.3–0.4 mm long; stigmas c. 1.0–1.2 mm long. Capsule subacute, equalling or ±exceeding<br />
perianth. Seeds 1.0–1.2 mm long, 0.6–0.7 mm wide; appendage indistinct, <strong>to</strong> 0.1 mm, fibrillate.<br />
Endemic <strong>to</strong> the South Is. of New Zealand. Similar <strong>to</strong> L. racemosa but inflorescence not<br />
interrupted, tepals with broad scarious-membranous margins, and longer style, capsule<br />
segments and seeds. L. masafuerana differs from L. traversii in having broader leaves with<br />
papillose-serrulate margins, broader bracts and suberect inflorescence. Two varieties are<br />
recognized within L. traversii; intermediates are known (Canterbury, Cave Stream, N.T.Moar<br />
& H.Nordenskiöld S118, UPS). E.Edgar, New Zealand J. Bot. 4: 164 (1966), mentioned<br />
