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. Trichopoda from the Greek 'trichos' meaning hairy and 'podus' meaning foot, stem or stalk; referring to its long pedicels (stalk), which is densely hairy above a joint near the apex and glabrous below.

Distribution and status

Found in the north-eastern part of South Australia, growing on heavy soils in floodplains and stony plains. Also found in all mainland states. Native. Common in south Australia. Rare in Western Australia. Common in the other states.

Plant description

Sprawling to erect shrub to 50 cm high with glabrous or hairy stems. Leaves narrowly ovate or elliptic, to 30 mm long and 15 mm wide, rounded at base, margins toothed; both surfaces green and hairy or the lower glabrous. Inflorescence solitary with yellow flower on a hairy stalk longer than the leaves, to 60 mm. Flowering between September and November. Fruits are hairy, brown transversely elliptic fruit to , 6.5 mm diameter, with 7-8 segments. Seeds are dark brown wedge-shaped seed to 2 mm long and 1 mm wide, covered in scattered hairs. Seed embryo type is folded.

Seed collection and propagation

Collect seeds between November and January. 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 one collection, the seed viability is high, at 90%. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
