Plant description

Bright green perennial herb forming dense cushions to 12 cm diameter. Leaves numerous, linear-filiform, acute, to 4.5 cm long and 0.8 mm wide; straight, spreading, soft, sparsely pilose in the basal half, innermost leaf reduced to a hyaline ( membranous) sheath. Flowering head broadly ovoid, to 3 mm long on a long erect stalk. Flowering between November and February. Fruits are small brown ovoid head at end of long stalk. Seeds are small orange-brown ellipsoid seed to 0.7 mm and 0.3 mm wide. Seed embryo type is broad.

Seed collection and propagation

Collect seeds between December and March. Collect fruit heads that are starting to dry off and turning pale straw colour by picking then off with your fingers. Place the heads in a tray for 1-2 week to dry. Then rub the heads with your hands or a rubber bung to dislodge the seeds. Pass the material through a sieve to separate the unwanted material. The finer material will contain both seeds (soft) and frass (hard) usually distinguishable from each other. With finer sieves, the seeds can be separated from the frass but this is not essential for storage or propagation. 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 one collection, the seed viability was high, at 100%.
