Name derivation:
Gnephosis of uncertain etymology but it is possible that Cassini, who descriped the genus in 1820 may derived it from the Greek 'gno-' and 'phos' meaning darkness, gloom and changing the first 'o' to 'e' to make it more pleasing to the ear. Drummondii name after James Drummond (1786-1863), a Scottish born botanist and naturalist who was an early settler in Western Australia.
Found on the Eyre Peninsula and the South-east in South Australia, growing on sandy clay or sandy loam in seasonally wet flats and depressions. Also found in Western Australia and Victoria.
Native. Uncommon in South Australia. Rare in Victoria. Common in Western Australia.

Seed collecting:
Collect heads or whole plants that are pale brown or turning brown. Each head should have numerous tiny seeds.
Seed cleaning:
Place the heads in a tray for a week to dry. Then rub the heads gently with your hands to dislodge the seeds. Use a fine sieve to separate the seeds from the unwanted material. Be careful as the seeds are very small. The seeds are dark brown and ovoid in shape. 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:
Seeds are non-dormant, viable seed should germinate readily.
