Plant description

Tussock perennial herb. Leaves to 50 cm long and 1.5 mm wide; terete, rigid; apex pungent. Inflorescences much shorter than leaves, the male with 3–7 spherical segments; the female with l or 2. Perianth 5 mm long; sepals white; petals yellowish. Flowering between August and October. Fruits are dark purple, almost globular capsule to 6 mm long; smooth. Seeds are yellow-brown, rounded wedge-shaped seed to 4 mm long and 3 mm wide. Seed embryo type is linear, underdeveloped.

Seed collection and propagation

Collect seeds between November and December. 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. From three collections, the seed viability was high, at 100%. This species has morpho-physiological dormancy and is difficult to germinate.
