Small slender tufted with shortly rhizomatous perennial rush with erect stems to 15 cm high, terete to compressed, covered with the fibrous remains of old leaf-sheaths. Leaves mostly basal, filiform, solid, dorsi-ventrally flattened, channelled above, shorter or longer than the stems. Inflorescence terminal, in clusters or solitary with many straw-brown to red-brown flowers. Flowering between December and February. Fruits are clusters of light brown to reddish-brown ellipsoid capsules with numerous seeds. Seeds are tiny deep red ovoid seed to 0.6 mm long and 0.4 mm wide, with deep reticulated surface. Seed embryo type is broad.
Seed collection and propagation
Collect seeds between January and April. Collect fruits either by picking off the mature heads, those turning brown and come-off easily or break-off the whole spikes. Place the heads in a tray and leave to dry for one to two weeks. Then rub the heads with a rubber bung to dislodge the seeds. Use a sieve to separate any unwanted material. Be careful, as the seeds are very small. Seeds are brown and hard. 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%.
