Name derivation:
Allittia named after William Allitt (1828 - 1893), who collected herbarium specimens, including the new lectotype specimen of Brachyscome cardiocarpa, in the south-west of Victoria while he was curator of the botanic gardens at Portland from the 1860s to the 1880s. Uliginosa from Latin meaning moist or marshy; referring to where the species is found.
Found only on Kangaroo Island and the lower South-east in South Australia, growing in swamps among heathland. Also found in Victoria.
Native. Rare in South Australia. Common in Victoria.
Plant description:
Perennial herb to 30 cm high, with no rhizomes. Stem very short, leaves all radical, sessile, narrowly oblanceolate, entire and sheathing at the base to 60 mm long and 6 mm wide; glabrous. Flowers large white to light purple daisy. Flowering between September and November.
Fruit type:
Large daisy heads with numerous seeds, usually turning brown when maturing.
Seed type:
Flat dark brown ovoid seeds to about 2 mm long, with serrated wings all around the margin.
Embryo type:
Spathulate fully developed.
Seed collecting:
Pick by hand, mature heads that are turning brown and contain semi-hard, brown seed inside.
Seed cleaning:
Place the heads in a tray to dry for 1-2 weeks. Then rub the heads gently by hand 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 viability was high, at 70%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
