Native. Common in South Australia. Uncommon in the Northern Territory and Queensland. Common in Western Australia.
Plant description:
Annual herb to 50 cm high with stems erect or ascending, branched and sparsely hairy. Base leaves petiolate, oblanceolate to 4.5 cm long, soon withering. Stem leaves sessile, cuneate to oblanceolate to 5 cm long and 10 mm wide, narrow at the base, dentate or lobed in the distal portion, sparsely hairy. Flower-head in loose leafy terminal cymes of 2-8 flowers, ray florets white or bluish. Flowering Between May and October.
Fruit type:
Brown round spiny fruit-head.
Seed type:
Brown seed to 2 mm long, covered in woolly hairs, with numerous, long and narrow barbed spines at one end.
Embryo type:
Spathulate fully developed.
Seed collecting:
Collect mature seed heads that are dried and turning brown by picking off the heads and placing them in a paper bag. Be careful as the heads are spiny.
Seed cleaning:
Leave the heads in the paper bag to dry for at least a week. No further cleaning required if only the heads are collected. If other material were collected, use a sieve to separate the unwanted material. Whole heads can be stored with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
