Census of South Australian plants (external link)     [genus Sida]
Name derivation:
Sida a Greek name used by Theophrastus for a water-lily, probably in reference to Nymphaea alba or for a pomegranate tree. Linnaeus  transferred the name to Malvaceae suppressing its primary, pre-Linnaean application. Intricata from the Latin 'intrico' meaning entangled; referring to its numerous tangled woody branches.
Distribution:
Found in the northern part of South Australia, growing on heavier loam and clay loam soils in a variety of habitats. Also found in all mainland states.
Status:
Native. Rare in Victoria. Uncommon in the Northern Territory. Common in the other states.
Plant description:
Much-branched, sprawling or upright, wiry herb or shrub to 30 cm high and wide, with numerous tangled woody branches with a spine-like tip, hairy when young. Leaves alternate, small, elliptical to ovate, to 9 mm long and 6 mm wide, grey-green, paler below, margin broadly toothed. Inflorescences solitary in leaf axils with yellow flowers. Flowers throughout the year depending on rainfall.
Fruit type:
Brown depressed-ovoid or conical, smooth and very thin-walled fruit to 4 mm long, shortly or densely hairy, with 5-8 segments.
Embryo type:
Folded.
Seed collecting:
Collect mature fruits, those that are turning pale straw colour and contain dark hard seeds.
Seed cleaning:
Place the capsules in a tray and leave to dry for two weeks. Then rub the capsules gently with a rubber bung or 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).
