Perennials, 1030 cm tall, loosely caespitose; rhizome ascending; stolons not seen. Basal leaves long, often equalling or overtopping stem, c. 932 cm long, (2) 36 mm wide; cauline leaves 35, to c. 25 cm long, often exceeding inflorescence; margins swollen, subglabrous to sparsely ciliate, smooth; apex obtuse. Lower 13 bracts leaf-like, 220 cm long, usually much overtopping inflorescence. Inflorescence subcongested, large lobulate head to 3 cm in diam., or composed of 13 subsessile and 18 pedunculate clusters; clusters large, ovoid, 8- to many-flowered, 715 mm long, often of several indistinct subclusters; peduncles straight, smooth, to c. 2 cm long. Bracteoles narrowly lanceolate, acuminate, to
c. 3 mm long, scarious, subentire or sparsely ciliate-fimbriate. Tepals ±equal, or some outer tepals longer by c. 0.51.0 mm, long acuminate, subaristate, (3.6) 4.56.0 (6.2) mm long, usually distally castaneous (to a variable length and degree), proximally pale brownish, sometimes wholly straw-brown; darker tepals with distinct narrow scarious margins.

| Geography: |
A remarkable endemic in Lord Howe Island. Rocky slopes, amongst scrub. Map 142., 50. LORD HOWE NORFOLK IS.: Lord Howe Is., summit of Mt Lingbird, Jun 1872, C.Moore 39 (para: K); Lord Howe Is., Mt Gower, c. 840 m, P.S.Green 1611 (K). |
| Notes: |
One of the most distinctive species in the sect. Luzula, distinguished by its very long, linear-lanceolate tepals, acute capsule, ±smooth, subglabrous leaf margin and its general habit. In its general habit it approaches L. crinita. |
