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 suppressing its primary, pre-Linnaean application. Petrophila from the Greek 'petros' meaning rock and 'philos' meaning love, referring to its rocky habitats.
Distribution and status
Found on the eastern half of South Australia, growing in hilly rocky places on shallow sandy and stony calcareous soils. Also found in Western Australia, Queensland and New South Wales. Native. Common in South Australia. Uncommon in Western Australia. Common in the other States.

Plant description
Erect perennial shrub to 1 m high, usually with one main stems and many smaller branches covered in hairs. Leaves alternate; oblong to lanceolate, to 40 mm long and 10 mm wide; felty, grey-green with a yellow-tinged, dense yellowish below, toothed margin. Inflorescence solitary in leaf axils, with yellow flowers on slender stalk. Flowers throughout the year. Fruits are hairy fruit to 7 mm long, with 6-7 segments. Seed embryo type is folded.
Seed collection and propagation
Collect seeds between January and December. Collect mature fruits, those that are turning pale straw coloured 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. This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
