Name derivation:
Wahlenbergia named by H.A Schrader in honour of Georg Göran Wahlenberg (1780-1851), a Swedish professor of botany. Queenslandica means of or from Queensland, Australia; referring to the location of the type specimen collected in 1958 from Grovesnor near Clermont in Queensland.
Distribution:
Found in the northern part of South Australia, growing in open sites in a variety of vegetation types. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Status:
Native. Common in South Australia. Common in the other states.
Plant description:
Perennial tufted herbs with a fleshy rootstock with stems to 90 cm high, upper parts glabrous, lower parts hairy. Leaves alternate or sometimes the lowermost opposite, to 60 mm long and 9 mm wide, obovate or oblanceolate, becoming linear up the stem, margins flat or sometimes undulate. Flowers terminal, blue, funnel-shaped with 5 narrow-triangular lobes, base often rather swollen in appearance. Flowers throughout the year.
Fruit type:
Brown capsule to 5 mm long.
Seed type:
Tiny orange elliptic seed to 0.7 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 two collections, the seed viability were high, ranging from 80% to 85%.
