Plant description

Annual herb to 13 cm high with erect to ascending, weak, sparsely hairy stems. Basal leaves linear or narrowly oblanceolate, entire or l-3-toothed, to 7.5 cm long, hairless. Other leaves linear or lobed with 3-5 linear acute segments, to 6 cm long, hairless. Flowers white appearing between August and October. Fruits are brown daisy-heads. Seeds are orange to dark-brown, cone-shaped seed to 1.5 mm and 1 mm, with striation down the length of the seed and covered with scattered wrinkles. 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. This species may have physiological dormancy that need to be overcome for the seed to germinate.
