Plant description

Small annual herb to 8 cm high with branches ascending to erect. Leaves ovate, lanceolate, obovate or linear, to 7 mm long and 2 mm wide; glabrous or cobwebbed. Flower-heads to 3 mm diameter with white-yellow flowers. Flowering between August and November. Fruits are pale brown head. Seeds are brown ellipsoid to ovoid seed to 0.6 mm long and 0.3 mm wide, covered in fine tubercules. Seed embryo type is spatulate fully developed.

Seed collection and propagation

Collect seeds between September and January. Collect heads or whole plants that are pale brown or turning brown. Each head should have numerous tiny seeds. Place the heads in a tray for a week to dry. Then rub the heads gently with your hands to dislodge the seeds. Use a fine sieve to separate the seeds from the unwanted material. Be careful as the seeds are very small. 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 100%. Seeds are non-dormant, viable seed should germinate readily.
