Plant description

Annual herb to 23 cm high with few, erect to decumbent, weak, hairy stems. Basal leaves spathulate and lobed to 4.5 cm long, soon withering. Other leaves spathulate to cuneate, distally lobed to 3 cm long and 6 mm wide, pubescent, glandular. Flowers small white daisy. Flowering between August and October. Fruits are brown-black daisy-heads. Seeds are black many angled seed to 2 mm long and 1 mm wide, with smooth bumpy surface. Seed embryo type is spatulate fully developed.

Seed collection and propagation

Collect seeds between October and December. Pick heads that are maturing, drying off, with brown seeds that dislodge easily. Place the seed-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. From one collection, the seed viability was high, at 90%. This species has physiological dormancy that needs to be overcome for the seed to germinate .Gibberellic acid (250 mg/L added to water agar) may improve germination, particularly under diurnal summer conditions or constant temperatures ranging from 17.5 - 28.5 degrees celsius.
