Name derivation:
Lagenophora from the Greek 'lagenos' meaning flask and 'phorus' suffix meaning carries; possibly referring to the urn-shaped cypsela. Gracilis from the Latin 'gracilis' meaning slender or graceful; referring to the slender flower stalk.

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.

Herb with short rhizome, roots fleshy. Leaves obovate to spathulate, to 80 mm long and 20 mm wide, sinuate to toothed with acute or obtuse teeth, sparsely to quite densely hairy. Flower-heads solitary on long slender stalk to 20 cm long, often darkly pigmented, with white to purple daisy flower. Flowering in Spring and summer.
Fruit type:
Brown head with exposed seeds.
Seed type:
Semi-flat brown, ovoid seed to 4 mm long and 1 mm wide.
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.
Seed viability:
From two collections, the seed viability were high, ranging from 90% to 95%.
