Census of South Australian plants (external link)     [genus Hibiscus]
Name derivation:
Hibiscus from the Latin 'hibiscum' which is from the Ancient Greek 'hibiskos' a name for mallow-like plant and possibly used by the physician Dioscorides for marshmallow plant. Krichauffianus named after Friedrich Edouard Heinrich Wulf Krichauff (1824-1904), a Danish-born South Australian politician, agriculturalist and a friend of Ferdinand von Mueller.
Distribution:
Found across the northern part of South Australia, growing on sand dunes, sandy rises and sand plain. Also found in all mainland states.
Status:
Native. Common in South Australia. Very rare in Victoria. Rare in Western Australia. Common in the other states.
Plant description:
Shrub to 90 cm high, pale-grey from the dense velvety hairs. Leaves densely hairy, ovate or ovate-lanceolate, to 40 mm long and 15 mm wide, margin serrated. Inflorescence solitary pale lilac or light purple flower. Flowers throughout the year.
Fruit type:
Hairy brown globular capsule to 10 mm long, enclosed by the fruiting calyx.
Seed type:
Dark brown reniform seed to 3 mm long and 2 mm wide, covered in long white hairs.
Embryo type:
Folded.
Seed collecting:
Collect capsules that are drying off and starting to turn brown. The seed inside should be brown and hard.
Seed cleaning:
Place the capsules into a tray and leave to dry for a week. Then rub the capsules by hand to dislodge the seeds. Use a sieve to separate the unwanted material. 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 was high, at 100%.
Seed germination:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
