Name derivation:
Lagenophora from the Greek 'lagenos' meaning flask and 'phorus' suffix meaning carries; possibly referring to the urn-shaped cypsela. Stipitata from the Latin 'stipatatus' meaning stalked; alluding to the more robust flower stalk.
Distribution:
Found on Kangaroo island, southern Mount Lofty Ranges and lower South-east in South Australia, growing in moist gullies and near water. Also found in Queensland, New South Wales, Victoria and Tasmania.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Herb with rhizome forming widely spreading stolons and fibrous roots. Leaves obovate to spathulate, to 60 mm long and 15 mm wide, deeply or shallowly dentate with 2-4 pairs of sinuate or acute teeth, hairy. Flower heads terminal, solitary on a robust stalk with white to blue or violet daisy flower. Flowering between October and February.
Fruit type:
Brown head with exposed seeds.
Embryo type:
Spatulate.
Seed collecting:
Pick heads that are maturing, drying off, with exposed brown seeds. Mature seeds should come-off easily.
Seed cleaning:
Place the heads in a tray and leave to dry for a week. Then gently rub the heads 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.
