Census of South Australian plants (external link)     [genus Chrysocephalum]
Name derivation:
Chrysocephalum from the Greek 'chryso' meaning golden and 'cephalus' meaning a head; referring to the golden flower heads. Semipapposum from the Latin 'semi' meaning half and 'pappos' meaning down or fluff; referring to the pappus bristles being white for two-thirds of their length.
Distribution:
Found in the central part of South Australia, from the Gammon Ranges, northern Eyre Peninsula to the upper South-east, growing in woodland and grassland on hills or rocky rises. Also found in Queensland, New South Wales, Victoria and Tasmania.
Status:
Native. Common in South Australia. Rare in Queensland. Common in the other states.
Plant description:
Erect perennial herb or subshrub to 60 cm high, aromatic with stems and branches covered in cottony or cobwebbed hairs. Leaves very variable, often dimorphic, those of successive seasons, or of vegetative and flowering stems differing in length and tomentum, linear to oblong, mostly to 50 mm long and 4 mm wide, acute to apiculate, base broad, margins flat, recurved or revolute, surfaces both grey-cottony, or upper surface glabrescent, sometimes scabrous. Flower-heads in clusters with golden-yellow or brownish daisy-flowers. Flowering between October and December.
Fruit type:
Pale brown fluffy daisy-head.
Seed type:
Brown ovoid seed to 1 mm long and 0.3 mm wide, covered in small tubercules and with pappus bristles finely barbellate and white for two-thirds of their length, upper third bright yellow.
Embryo type:
Spatulate.
Seed collecting:
Collect whole heads that are brown and fluffy or collect just the seeds by plucking it off with your fingers. Mature seeds are easily removed.
Seed cleaning:
Place the heads in a tray for a week to dry. Then pluck the seeds from the head with your finders. Viable seeds will be fat and brown. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed viability:
From one collection, the seed viability was low, at 15%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
