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. Hispidula means covered with minute stiff hairs or fine bristles.
Distribution:
A very common species found across South Australia except on Kangaroo Island and the lower South-east, growing in a wide variety of communities and soils ranging from heavy clays to shallow stony soils. Also found in all mainland states.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Annual prostrate or ascending herb to 10 cm high, hairy. Leaves sessile, cuneate to oblanceolate to 2 cm long and 7 mm wide. Flower-heads numerous, in dense leafy cymose panicles, ray florets yellow. Flowering between June and October.
Fruit type:
Dense round spiny fruit-head.
Seed type:
Red-brown semi-flat pyrimid-shaped seed to 3 mm long, covered with hairs and with spines at the wider end.
Embryo type:
Spathulate.
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. 1. Germination 100%  on 1% w/v agar, 8/16 dark/light, 10°C. 2. Germination 100% on 1% w/v agar 8/16 dark/light, 15°C. 3. Germination 100% on 1% w/v 8/16 dark/light, 20°C. See http://data.kew.org/sid
