Perennial herb, 0.3-1.2 m high; caulescent; stems short, woody, with persistent, reticulate fibres of old leaf bases. Leaves grass-like; blade semiterete, up to 400 mm long, ± 2 mm wide. Flowers: in a divaricately branched raceme, up to 300 mm high; scape arcuate at base, glabrous; pedicels patent, up to 15 mm long; perianth white with 2 dark spots at base of lobes; Sep.-Mar. Fruit glabrous.
Inflorescence up to 35 cm long, ± divaricately branched; peduncle (scape) terete, glabrous, curving ± abruptly outwards above the leaf sheaths to remain ± decumbent or becoming erect; racemes 3–8, up to 21 cm long; bracts minute, membranous, acute; pedicels patent, 7–24 mm long in fruit.
Leaves few, up to 50 cm long, 2 mm in diameter, subterete, flattened above; basal sheaths long cylindrical, 5–8 mm in diameter, with reticulate thickening, tightly clasping the young leaves and peduncle base and persisting as long coarse fibres.
Psammophyte, up to 400 mm tall, producing short, aerial stems. Leaves few; leaf bases long, with reticulate thickenings. Inflorescence usually branched. Perianth maculate. Flowers cream with brown stripes.
Capsule small, 2.5–4 mm in diameter, subglobose, 3-lobed, stipitate above the cup formed by the persistent perianth base, smooth, without tubercles, maculate, becoming rugose.
Perennial grass-like herb, up to 50 cm tall, with a short aerial stem from a small rhizome; roots many, stout, fibrous, root hairs producing a felted covering.
Perianth segments spreading or ± recurved, c. 6–10 mm long, maculate; filaments erect, shortly scabrid.
Stem up to 6 cm long, woody, usually enclosed within a fibrous coat.
Seeds apparently 1 per locule, black, c. 1.5 mm long.
