Etymology

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 habitat.

Distribution and status

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. Fruits are large daisy heads with numerous seeds, usually turning brown when maturing. Seeds are flat, dark brown, ovoid to 2 mm long, with serrated wings all around the margin. Seed embryo type is spathulate fully developed.

Seed collection and propagation

Collect seeds between November and January. Pick by hand, mature heads that are turning brown and contain semi-hard, brown seed inside. 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 is usually high. Seeds are non-dormant, viable seed should germinate readily.
