Etymology

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.

Plant description

Annual herbs to 6 cm high, simple or branched. Leaves oblanceolate, obovate, elliptic or narrowly elliptic, to 11 mm long 1 mm wide, apex sometimes glassy, usually with a dense cover of scale-like hairs. Flower-heads dense oblong-shaped with yellow flowers. Flowering between August and November. Fruits are creamy to pale brown heads. Seeds are tiny purple ovoid seed to 0.5 mm long and 0.3 mm wide, covered in scattered tubercules. Seed embryo type is spatulate.

Seed collection and propagation

Collect seeds between October and February. Collect heads or whole plants that are pale brown or turning brown. Each head should have numerous tiny seeds. 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. From one collection, the seed viability was high, at 100%. Seeds are non-dormant, viable seed should germinate readily.
