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 changing its primary, pre-Linnaean application. Phaeotricha from the greek 'phae' meaning dark and 'trichos' meaning hairs; possibly referring to its reddish brown or rust-coloured hairs on the younger parts of the plant.
Found far north-western part, upper Eyre Peninsula, northern Flinders ranges and the Olary Ranges in South Australia, growing on rocky or gravelly ranges and hills. Also found in Western Australia, Northern Territory, Queensland and New South Wales.
Native. Common in South Australia. Uncommon in Western Australia, Queensland and New South Wales. Common in the Northern Territory.
Plant description:
Erect shrub to 2 m high, with thick velvety dense hairs, golden or rusty hairs on the younger parts. Leaves ovate to lanceolate, to 75 mm long and 24 mm wide, margin toothed, covered in dense velvety hairs. Inflorescence solitary in the axils of leaves or in axillary clusters of 2-6 yellow flowers. Flowering between July and October.
Fruit type:
Hairy brown globular fruit to 6 mm diameter, conical in the centre, with 5 segments.
Embryo type:
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).
