SA Census:
Census of South Australian plants (external link)     [genus Gnephosis]
Name derivation:
Gnephosis of uncertain etymology. Tenuissima from the Latin 'tenuis' meaning very slender; alluding to the slender habit of this species.
Distribution:
Found across much of South Australia except on Kangaroo island, York Peninsula, Mount Lofty Ranges and the South-east, growing on a variety of soils and habitats. Also found in all mainland states.
Status:
Native. Common in South Australia. Rare in Victoria. Common in the other states.
Plant description:
Annual herbs to 15 cm high, simple or branched. Leaves elliptic to linear or obovate to oblanceolate, to 30 mm long and 4 mm wide, apex often glassy, scale-like hairs usually present. Flower heads club-shaped or spike-like, to 22 mm long and 7 mm diameter with yellow flowers. Flowering between August and December.
Fruit type:
Creamy to pale brown head.
Embryo type:
Spatulate.
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. 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 germination:
Seeds are non-dormant, viable seed should germinate readily.
