JUNCACEAE (Luzula)
dwarf plants from C Otago as a part of the variation range of L. traversii. The absence of
herbaceous bracts might indicate a distinct taxon.

Stamens usually 6; anther/filament ratio c. 2; basal leaves usually to 2 mm wide 26b. var. tenuis
26a. Luzula traversii (Buchenau) Cheeseman var. traversii
Basal leaves usually up to 12–15 cm long, (1–) 2–4 (–5) mm wide; cauline leaves 2 or 3,
usually up to 6–7 cm long. Tepals 1.8–2.2 (–2.5) mm long. Stamens 3– (4–5); anthers
0.5–0.6 mm long; filaments 0.4–0.5 mm long. Capsule castaneous brown; capsule segments
