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. Lappulacea from the Latin 'lappa' meaning burr, alluding to the burr-like fruit.
Found in the central part of South Australia, between Lake Torrens and Lake Frome south to Peterborough. Also found in all other mainland states.
Native. Uncommon in South Australia. Rare in the Northern Territory. Uncommon in Victoria. Common in the other states.
Plant description:
Perennial herb or undershrub to 50 cm high with hairy, erect, much-branched, wiry stems, becoming woody in the lower part. Base leaves petiolate, cuneate, toothed or pinnatifid, to 6 cm long and 8 mm wide, soon withering. Stem leaves sessile, linear to oblanceolate, entire to pinnatifid, to 2.5 cm long and 4 mm wide, narrowed at the base, scabrous-pubescent. Flower-head in very loose leafy terminal cymes with solitary or 2-4 flowers, ray florets yellow. Flowering much of the year.
Fruit type:
Brown round spiny fruit-head.
Seed type:
Yellow-brown pyrimid-shaped seed to 2 mm long, with numerous 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.
