Name derivation:
Velleia named after Thomas Velley (1748-1806), an English botanist. Cycnopotamica from the Greek 'kyknos' meaning swan and 'potamos' meaning river; possibly referring to the Swan River in Western Australia where the tyre specimen was collected.
Distribution:
Found on central Eyre Peninsula, around the Gawler Ranges, growing on sandy or clayey soils in open habitats and often in cultivated land. Also found in Western Australia.
Status:
Native. Rare in South Australia. Common in Western Australia.
Plant description:
Annual herb to 20 cm high. Leaves forming a rosette, oblong to oblanceolate to spathulate, attenuate into a short petiole, acute to obtuse, to 60 mm long and 12 mm wide, serrate to lyrate-pinnatifid, sparsely villous to glabrescent. Peduncles ascending or decumbent, terete, to 20 cm long, glabrous or subglabrous. Flowers small, pink or mauve to white, more or less pubescent outside, glabrous inside, sepal free. Flowering between August and October.
Fruit type:
Pale brown globular fruit to 7 mm diameter, 2-valved, inflated, pubescent; seeds orbicular, c. 3.5 mm diam., the body comma-shaped, broadly winged.
Seed type:
Yellow-orange, circular disk seed to 5 mm diameter, pitted in the centre, pointy at the base and with a winged around margin.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect capsules that are maturing, turning brown, easily split open and with yellow-orange seeds inside.
Seed cleaning:
Place the capsules in a tray and leave to dry for a week. Then rub the capsules with your hands 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 90%.
