Plant description

Dioecious rhizomatous, perennial herb to 0.7 m high; clumps to 0.2 m wide. Leaves to 80 cm long and 2.5 mm wide; filiform or terete; hard and stiff, smooth, plano-convex or slightly channeled, with brown or black basal sheaths. Male flowers spreading or drooping. Female flowers similar but the panicle usually narrower and shorter. Flowers green-purple-brown. Flowering between May and December. Fruits are ovoid to globular capsule to 5 mm long; smooth. Seeds are yellow to brown, rounded wedge-shaped seed to 5 mm long and 3 mm wide. Seed embryo type is linear, underdeveloped.

Seed collection and propagation

Collect seeds between December 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. From three collections, the seed viability was high, at 100%. This species has morpho-physiological dormancy and can take several weeks to germinate.
