Etymology
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 changing its primary, pre-Linnaean application. Filulifera from Latin 'fibula' meaning a broach and 'fera' meaning to bear; referring to the pin-like stipules at the leaf-stem junctions.
Distribution and status
Found in the northern part of South Australia, growing in a wide range of habitats including rocky slopes, dunes and swampy ground on clay, sandy or gravelly soils. Also found in all mainland states. Native. Common in South Australia. Rare in Victoria. Common in the other states.

Plant description
Prostrate to procumbent spreading shrub to 40 cm high with hairy branches. Leaves alternate, narrow-ovate to elliptic, to 40 mm long and 20 mm wide, densely hairy on both surface, pale on the underside, margin tooted, stalk o 10 mm long, stipules at leaf-stem junctions pin-like, remaining for some time. Inflorescence solitary or in clusters of 3-7 yellow flowers, on very slender stalk. Flowering between March and October. Fruits are brown, flatted globular fruit to 5 mm diameter, with 5-8 segments, each with a wrinkled rounded top and flat net-like face. Seeds are dark brown wedge-shaped seed to 2 mm long and 1 mm wide. Seed embryo type is folded.
Seed collection and propagation
Collect seeds between July and December. Collect mature fruits, those that are turning pale straw colour and contain dark hard seeds. 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. From two collections, the seed viability was high, ranging from 80% to 100%. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
