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. Densiflora from Latin for densely flowered.

Endemic to South Australia and found in the Mount Lofty and Flinders Ranges, in open woodlands. Native. Common in South Australia.
Herbarium regions: Flinders Ranges, Eyre Peninsula, Northern Lofty, Murray, Yorke Peninsula, Southern Lofty, Green Adelaide
NRM regions: Adelaide and Mount Lofty Ranges, Eyre Peninsula, Northern and Yorke, South Australian Arid Lands, South Australian Murray-Darling Basin

Dioecious perennial tussock herb with bright green rigid leaves with 3 tiny points at the tip, to 60 cm long; basal sheaths becoming fibrous. Flower white. Flowering between August and November. Fruits are ovoid to globular capsule to 6 mm long; smooth, truncate at the summit, sometimes slightly curved. Seeds are yellow-brown, rounded wedge-shaped seed to 6 mm long and 3 mm wide. Seed embryo type is linear, underdeveloped.

Collect seeds between November and December. 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 two collections, the seed viability was high, at 100%. This species has morpho-physiological dormancy and will germinate slowly over weeks to months.
