Plant description
Perennial herb with short stems forming dense tussocks or mats. Basal sheaths becoming fibrous. Leaves to 50 cm long and 2 mm wide; filiform, scabrous. Male inflorescence much shorter than leaves, scape exposed for up to 5 cm, rachis usually well branched, to 10 cm long. Female inflorescence to 10 mm diameter; scape usually exposed for up to 3 cm. Flowers yellow, between August and November. Fruits are pyramid-shaped capsule. Seed embryo type is linear, underdeveloped.
Seed collection and propagation
Collect seeds between November and January. Collect mature fruits, turning brown with a hard seed inside, or when they are starting to split. Place the capsules in a tray and leave to dry for one to two weeks. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. This species has morpho-physiological dormancy and can take several weeks to germinate.
