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. Cymbacantha from the Greek 'kymbe' meaning boat and 'akantha' meaning thorn, spine; referring to the boat-shaped spine on the seed.
Distribution:
Found across much of the arid part of South Australia, growing on sandy soils in woodland and shrub communities. Also found in the Northern Territory, New South Wales and Victoria.  
Status:
Native. Common in South Australia. Rare in Victoria. Common in the other states.
Plant description:
Annual or perennial herb to 40 cm high with erect, branching and hairy stems, becoming woody at the base. Base leaves petiolate to 9 cm long, soon withering. Stem leaves sessile, broad-linear to spathulate to 8 cm long and 27 mm wide, pinnatipartite to slightly dentate, scabrous-pubescent. Flower-head in loose cymes of 2-5 flowers, ray florets yellow. Flowering between July and October.
Fruit type:
Brown round spiny fruit-head.
Seed type:
Yellow-brown seed to 6 mm long with two large spine shaped like a boat 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.
