Census of South Australian plants (external link)     [genus Calotis]
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.
Distribution:
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.
Status:
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:
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 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.
