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. Gracilenta from the Latin 'gracilis' meaning slender; alluding to the species habit.
Distribution:
Found many in the southern parts of South Australia, with scattered occurrences further north, growing on sandy or gravelly soils. Also found in Western Australia, New South Wales, Victoria and Tasmania.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Annual, single- or few-stemmed herbs, hairy, with stems to 35 cm long, often unbranched below the inflorescence. Leaves opposite, becoming alternate up the stem, sometimes alternate throughout, to 40 mm long and 11 mm wide, obovate or broadly elliptical, becoming lanceolate up the stem, margins flat or sometimes undulate. Flowers terminal, blue or sometimes pink or white, funnel-shaped with 5 narrowly oblong lobes. Flowering between July and February.
Fruit type:
Brown ellipsoid to globose capsule to 7 mm long and 6 mm wide.
Seed type:
Tiny orange-brown elliptic seed to 0.5 mm long and 0.2 mm wide.
Embryo type:
Spatulate under-developed.
Seed collecting:
Collect capsules that are maturing, drying and turning brown with brown 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.
