Census of South Australian plants (external link)     [genus Hyalosperma]
Name derivation:
Hyalosperma from the Greek 'hyalos' meaning glass and 'sperma' meaning a seed; refers to the transparent wing of the achenes. Semisterile from Latin meaning semi sterile.
Distribution:
Found mainly in the central part of South Australia, growing on a variety of soils, such as heavy clay, silty loam, saltmarsh, and sand. Also found in Queensland, New South Wales and Victoria.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Erect annual herb to 16 cm tall, branching at and above base, branches slender, sparsely cottony or glabrous. Leaves alternating up the stems, to 18 mm long and 1 mm wide, flattened cylindrical, sparsely hairy to hairless, with blunt or pointed tips. Flower-heads  cup-shaped or hemispherical, borne singly at the ends of the stems with orange to yellow papery daisy flowers. Flowering between August and October.
Fruit type:
Golden brown papery daisy head.
Embryo type:
Spatulate.
Seed collecting:
Collect whole plants that are drying off and turning golden brown. Each head should have numerous tiny seeds.
Seed cleaning:
Place the plant 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.
