Name derivation:
Hyalosperma from the Greek 'hyalos' meaning glass and 'sperma' meaning a seed; refers to the transparent wing of the achenes. Glutinosum from the Latin 'gluten' meaning glue; alluding to the resinous secretion covering the type specimen.
Distribution:
Found in the central part of South Australia, growing on sandy in exposed situations in a wide variety of soils
in woodlands and shrublands. Also found in Western Australia, New South Wales and Victoria.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Annual herb to 20cm tall or sprawling, glabrous or sparsely cottony. Leaves alternating up the stems, to 16 mm long and 1mm wide, cylindrical, sparsely hairy to hairless, tips blunt. Flower-heads , bell- or funnel-shaped becoming hemispherical, borne singly at the end of the stems with yellow daisy flowers. Flowering between August and October.
Fruit type:
Dense yellow or pale brown papery head.
Embryo type:
Spatulate.
Seed collecting:
Collect heads or whole plants that are drying off and turning brown. Each head should have numerous tiny seeds.
Seed cleaning:
Place the heads in a tray for a week to dry. Then rub the heads gently with your hands to dislodge the seeds. Use a fine sieve to separate the seeds from the unwanted material. Be careful as the seeds are very small. 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 germination:
Seeds are non-dormant, viable seed should germinate readily.
