Distribution and status

Endemic to South Australia and found in the Flinders Ranges and the southern Mount Lofty Ranges growing on steep rocky slopes on clay-loam; prolific particularly after fires. Native. Rare in South Australia.

Plant description

An open erect shrub to 2 m tall, covered in fine hairs. Leaves linear, rarely narrowly elliptic to obovate; sessile, to 50 mm long and 6 mm wide (juvenile leaves larger); entire, pubescent, the lower leaves glabrescent. Flowers solitary; large white to creamy-yellow with five star-like petals. Flowering between May and November. Fruits are papery brown ovoid to pear-shaped capsule to 9 mm long, containing numerous seeds. Seeds are bean-shaped brown seeds to 3 mm long and covered with honeycomb depressions. Seed embryo type is linear fully developed.

Seed collection and propagation

Collect seeds between October and January. Collect maturing capsules, those that are turning brown with hard brown seeds inside. Monitor the plants as the capsules will dry, split and disperse the seeds in a short space of time. Using of a small bag (ie. Organza bags) to enclose the developing capsules will help to increase the chances of collecting sufficient viable seeds. Place the capsules in a tray and leave to dry for a week. Then gently rub the capsules 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 at 100%. This species is generally difficult to germinate, it has physiological dormancy and complex germination requirements.
