Name derivation:
Lobelia named after Mathias de Lobel (1538-1616), physician to William of Orange and then botanist to James I of England. Pratioides means resembling Pratia, a genus named after Charles Prat-Bernon, a midshipman on Freycinet's scientific voyage around the world, died just after departure in 1817.
Found in the South-east in South Australia, growing in swampy areas. Also found in New South Wales, Victoria and Tasmania.
Native. Rare in South Australia. Rare in New South Wales and Tasmania. Common in Victoria.
Plant description:
Prostrate to decumbent perennial herbs with often fleshy adventitious roots along the branches, with short spreading hairs at least on young branches. Leaves with no stalk with a long cuneate base, to 25 mm long and 5 mm wide, with widely spaced teeth or serrations along the whole margin, with short spreading hairs on young leaves. Flowers singularly in the axils of leaf-like bracts at the apex of branches, with off-white or tinged blue flowers. Flowering between November and January.
Fruit type:
Yellow, ovoid scapsule to 5 mm long, ridged, hairy.
Seed type:
Brown ovoid seed to 0.8 mm long and 0.5 mm wide, with fine wrinkled surface.
Embryo type:
Linear under-developed.
Seed collecting:
Collect mature capsules, those that are fat, turning a pale straw colour and contain brown seeds. Can be time consuming to find mature capsules.
Seed cleaning:
Place the capsules in a tray and leave to dry for one weeks. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate 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:
From one collection, the seed viability was high, at 100%.
