Name derivation:
Phyllanthus from the Greek 'phyllon' meaning a leaf and 'anthos' meaning a flower; referring to some foreign species where the flowers grow on the edges of dilated leaf-like branchlets. Lacunarius from Latin meaning growing in lake, pond or dykes; referring to the species habitat in river and creek beds and on flood plains.
Found on the eastern part of South Australia, north of the Murray, growing in river and creek beds, along banks and on flood plains. Also found in Queensland, New South Wales and Victoria.
Native. Common in South Australia. Rare in Victoria. Uncommon in the other states.
Plant description:
Annual her to 25 cm tall, with prostrate to ascending glabrous stems. Leaves alternating up the stems, to 20 mm long and 7 mm wide, flat, glabrous, tips rounded with a short point. Male and female inflorescence on the same plant with small (less than 3 mm across) reddish with white margins flowers. Inflorescence in clusters on short stalks at the bases of the leaves, with 2-3 male flowers and one female flower. This species is similar to Phyllanthus lacunellus which is a perennial with a woody base, growing in sandy soils, fruiting bodies are 2-3 mm in diameter and has a fine wrinkled seed texture. Flowers throughout the year dependence on rainfall.
Fruit type:
Green depressed globular capsule to 3 mm long and 4.5 mm wide, glabrous, with three lobes.
Seed type:
Orange-brown sectoroid seed to 1.5 mm long and 1.5 mm wide, with a striated surface.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect individual mature capsules, those that are drying off, fat and contain dark hard seeds or pull out the whole plant (annual) to allow capsules to continue to mature. Green capsules can be collected if the seeds are dark and hard.
Seed cleaning:
Place the capsules in a tray and leave to dry for one to two weeks. Then gently rub the capsules with a rubber bung to dislodge the seeds. Use a sieves to separate the unwanted material. 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.
