Name derivation:
Ammannia named after Johannes Ammann (1707-1741), a Swiss botanist, Fellow of the Royal Society of London and Professor of botany at St Petersburg. Multiflora from the Latin 'multus' meaning many and 'floris' meaning flower.
Distribution:
Found in the north-eastern part and alon gthe Murray River in South Australia, growing on flood plains of rivers and creeks. Also found in all mainland states.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Erect, rigidly-branched herb with 4-angled stems, up to 60 cm high. Leaves narrow-oblong to lanceolate to 50 mm long and 8 mm wide, upper surface minutely scabrous. Peduncles up to 6 mm long. Flowers pink to purple. Flowers throughout the year.
Fruit type:
Reddish, papery globular capsule to 2 mm diameter.
Seed type:
Very small concave brown seed to 0.4 mm long and 0.4 mm wide.
Seed collecting:
Fruit can be collected all year round but is dependent on rainfall. Collect mature capsules, those that are turning reddish brown in colour and contain brown seeds. Whole stem containing many clusters of fruit can be collected.
Seed cleaning:
Place the capsules in a tray and leave to dry for two weeks. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Be very 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:
From two collections, the seed viability were high, at 100%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily.
