Census of South Australian plants (external link)     [genus Frankenia]
Name derivation:
Frankenia named after Johan Frankenius (1590-1661), a Swedish botanist. Plicata from the Latin 'plicare' meaning folded in plaits or braided.
Distribution:
Endemic to South Australia and found in the north-eastern part, growing in swales and hillside channels on loamy sands to clay.
Status:
Native. Rare in South Australia.
Plant description:
A small, densely branched, hairy, erect or prostrate shrub with 25 cm long stems. Branches are differentiated into long and short-shoots. The grey-green linear leaves are stalked, to 6 cm long, usually hairless, and dotted by glands above or sometimes covered with stiff short hairs. The margins are tightly in-rolled and hide the midrib below. Flowers occur on 1–4 nodes of the upper branches, are commonly solitary or in groups of 2–3. Flowering between September and October.
Fruit type:
Brown cylindrical capsule.
Seed type:
No information
Embryo type:
Spatulate fully developed.
Seed collecting:
Look at the tip of branches for dried flower heads. Collect the heads that are cylindrical, brown, slightly fat at the base. This should contain small ovoid seed.
Seed cleaning:
Place the flower heads in a tray and leave to dry for at least a week. Then rub the dried heads gently 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 viability:
Seed set can be low but viability is high. From one collection, the seed viability was high, at 100%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
