SA Census:
Census of South Australian plants (external link)     [genus Velleia]
Name derivation:
Velleia named after Thomas Velley (1748-1806), and English botanist. Arguta meaning sharp toothed; referring to the species serrated leaves.
Distribution:
Grows in drier regions in mallee on sandy soils and rocky sites and found across most part of South Australia except the southeast and northeast regions. Also found in Western Australia, New South Wales and Victoria.
Status:
Native. Common in South Australia. Rare in Victoria. Uncommon in the other states.
Plant description:
Perennial herb with a robust woody rootstock. Leaves oblanceolate to elliptic, serrate to deeply incised, glabrous or slightly pubescent towards the margin, to 12 cm long and 10 mm wide forming a rosette. Inflorescence a scape to 40 cm high. Flowers on a long spur, corolla deep yellow, brownish towards the throat. Flowering between July and January.
Fruit type:
Brown ovoid, 4-valved capsule to 9 mm long, densely pubescent with a glabrous mucro.
Seed type:
Pale brown, semi-flat, broad-elliptic seed to 4 mm diameter, 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 brown 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 two collections the seed viability were high, ranging from 95% to 100%.
