Name derivation:
Lomandra from the Greek 'loma' meaning edge, border or fringe and 'andros' meaning a male; alluding to the circular margin of the anthers in some species. Filiformis from Latin meaning thread form; alluding to the shape of the leaf. Coriacea from the Latin 'corium' meaning leather; alluding to the texture of the leaf.
Found only in the lower South-east in South Australia, growing on shallow gravelly-clay or sandy soils of rocky or stony areas, often in dry open-forests and woodlands. Also found in Queensland, New South Wales and Victoria.
Native. Rare in South Australia. Common in the other states.

Male inflorescence often up to a half as long as leaves, with a few branches, branches often whorled, axes scabrid, often yellowish. Female inflorescence smaller, and axes often less scabrid.

Seed cleaning:
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.
Seed viability:
From one collection, the seed viability was high, at 100%.
Seed germination:
This species has morphophysiological dormancy and can take several weeks to germinate.
