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. Plumulifera from the Latin 'plumulus' meaning feather and 'fera' to bear; alluding to the feather-like woolly hairs on the seed.
Distribution:
Found across the northern part of the South Australia, growing on silty sand and loam, in floodplains and dried river bed. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Annual herb to 50 cm high with stems erect or ascending, branched, sparsely hairy. Base leaves petiolate, oblanceolate, to 4.5 cm long, soon withering. Stem leaves sessile, cuneate to oblanceolate, to 5 cm long and 10 mm wide, narrowed at the base, dentate or lobed in the distal portion, sparsely hairy. Flower-head in loose leafy terminal cymes of 2-8 flowers, ray florets white to mauve. Flowering between April and October.
Fruit type:
Brown round spiny fruit-head.
Seed type:
Brown seed to 2 mm long, covered in woolly hairs, with numerous, long and narrow barbed spines at one end. Barbs on the spiny are longer than in Calotis multicaulis.
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.
