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. Brachysiphonius from the Greek 'brachus' meaning short and 'siphon' meaning a tube; referring to the calyx lobes which are united in the lower part forming a short tube at the base.
Distribution:
Found in the central and north-eastern parts of South Australia, growing on heavy soil in Chenopod plains, gibber plains and near breakaways. Also found in all mainland states.
Status:
Native. Common in South Australia. Very rare in Victoria. Common in the other states.
Plant description:
Low sometimes prostrate sub-shrub to 30 cm high, resprouting after rain from a perennial rootstock. Leaves green with scattered hairs, lower leaves obovate, crenate, upper leaves deeply 3-lobed, to 5 cm long and wide. Inflorescence solitary on a long stalk with pale pink flower, calyx lobes united in the lower part forming a short tube. Flowering between August and October.
Fruit type:
Brown globular, glabrous capsule to 12 mm long.
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 germination:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
