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. Anthemoides means resembling Anthemis, genus name for chamomile.
Distribution:
Found in one location in South Australia, next to the township of Frances, growing in cracking clay grassy woodland. Also found in New South Wales and Victoria.
Status:
Native. Very rare in South Australia. Common in the other states.
Plant description:
Stoloniferous perennial herb to 20 cm high, glabrous or with a few small scattered hairs. Basal leaves in a rosette, pinnate with pinnatifid or linear segments, to 12 cm long, lamina glabrous, long-petiolate. Flower-heads to 5 mm diameter, solitary on bracteate scapes to 20 cm long, ray florets white. Flowering between September to February.
Fruit type:
Round spiny fruit-head.
Seed type:
Red-brown flatten pyrimid-shaped seeds to 1.5 mm long with rigid wings on the margins, hairs and spiny 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 viability:
This species produce very few viable seeds.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
