SA Census:
Census of South Australian plants (external link)     [genus Wahlenbergia]
Name derivation:
Wahlenbergia named by H.A Schrader in honour of Georg Göran Wahlenberg (1780-1851), a Swedish professor of botany. Tumidifructa from the Latin 'tumida' meaning swollen and 'fructus' meaning fruit.
Distribution:
Found in the drier parts of South Australia, growing  in open sites in a variety of plant communities of arid and semi-arid regions. Also found in all mainland states.
Status:
Native. Common in South Australia. Rare in Victoria. Common in the other states.
Plant description:
Perennial tufted herbs with a fleshy rootstock and stems to 90 cm long, upper parts glabrous, lower parts sparsely hairy. Leaves alternate or sometimes the lowermost opposite, to 60 mm long and 12 mm wide, obovate, becoming linear up the stem, margins flat or undulate. Flowers terminal, blue, sometimes pink or white, funnel-shaped with 5 narrow-triangular lobes which are less than twice as long as the base. Flowers throughout the year.
Fruit type:
Brown globular, cylindrical or sometimes conical capsule to 9 mm long, swollen in appearance. 
Seed type:
Tiny orange elliptic seed to 0.6 mm long and 0.3 mm wide.
Embryo type:
Spatulate under-developed.
Seed collecting:
Collect capsules that are maturing, drying and turning orange with hard seeds inside.
Seed cleaning:
Place the capsules in a tray and leave to dry for a week. Then rub the capsules gently with your hands 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 low, at 30%.
