Name derivation:
Calotis from the Greek 'kalos' meaning beautiful and 'otos' meaning ear, after the first species named in the genus Calotis cuneifolia which has an ear-shaped pappus.
Found from the north-west corner to the New South Wales border in South Australia, in moist open areas. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Native. Common in South Australia. Uncommon in Western Australia and Quensland. Common in the other States.
Plant description:
Perennial herb to 40 cm high; stems erect, branched, strigosehirsute, becoming woody at the base only. Base leaves petiolate, oblanceolate, to 7 cm long and 18 mm wide, coarsely serrate. Stem leaves sessile, oblanceolate to cuneate, to 6 cm long and 12 mm wide, acute, entire to shallowly dentate, subamplexicaul at the base, strigose to scabrous. Flower-heads in loose leafy terminal cymes of 4-30 flowers, ray florets yellow. Flowering between May and October.
Fruit type:
Brown, dense round spiny fruit-head.
Seed type:
Brown wedge-shaped seed to 2 mm long, with numerous hairy spines at one end.
Embryo type:
Spatulate, 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 seperate the unwanted matyerial. 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.
