Name derivation:
Luzula possibly from the Italian 'luzziola' meaning sparkle or a fire-fly or from the Latin 'luxulae 'meaning light; probably alluding to the sparkling and quivering character of the heads when wet with dew. flaccida from the Latin 'flaccidus' meaning slack or flaccid; referring to its drooping leaf-blades.
Distribution:
Found in the southern Mount Lofty Ranges and the lower South-east in South Australia, growing in moist rather shady sites in grassy woodland or open grassland. Also found in Queensland, New South Wales, Victoria and Tasmania.
Status:
Native. Rare in South Australia. Uncommon in Queensland. Common in the other states.
Plant description:
Loosely tufted perennial sedge with flowering stems 25 cm high, rarely bulbous at base. Leaves flat, to 6 mm wide with sparely hairy margins and a thick callous obtuse tips. Inflorescence 1-6 clusters with many yellowish to light brown flowers at the end of a long stalk. Flowering between August and November.
Fruit type:
Dense clusters of brown capsules.
Seed type:
Dark brown to black ellipsoid seed to 0.9 mm long and 0.8 mm wide, with a large white fleshy appendage at one end.
Embryo type:
Broad.
Seed collecting:
Collect fruits either by picking off the mature heads, those turning brown and come-off easily or break-off the whole spikes.
Seed cleaning:
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.
Seed viability:
From one collection, the seed viability was high, at 100%.
