Name derivation:
Lobelia named after Mathias de Lobel (1538-1616), physician to William of Orange and then botanist to James I of England. Simplicicaulis means unbranched stem; referring to its single erect flowering stem.
Found in the South-east in South Australia, growing in the understorey of open forest, ephemeral after fire or other disturbance. Also found in New South Wales, Victoria and Tasmania.
Native. Rare in South Australia. Rare in New South Wales. Common in the other states.
Plant description:
Annual or perennial herbs with a tap root, and one to few stiffly erect stems up to 35 cm long, glabrous. Leaves sessile, linear-oblanceolate with a cuneate base and often distant marginal teeth at the base of the plant but often already dried up by the time the flowers are open becoming linear-lanceolate to awn-shaped on the stems, 1to 3.5 mm long 4 mm wide, glabrous. Flowers along a long spike with blue flowers with lobes triangular, the tube off-white becoming blue like the lobes and split along the upper side, the upper 2 lobes short, the lower 2 lateral lobes longer but about half the length of the oblanceolate median lobe. Flowering between November and January.
Fruit type:
Brown obovoid capsule to 8 mm long.
Seed type:
Brown triangular seed to 0.7 mm long and 0.3 mm wide, smooth.
Embryo type:
Linear under-developed.
Seed collecting:
Collect mature capsules, those that are fat, turning a pale straw colour and contain brown seeds.
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.
