Upright or spreading perennial shrub to 100 cm tall, covered in velvety hairs. Leaves ovate, to 7 cm long and 4 cm wide. Flowers solitary or in groups with large yellow flowers. This subspecies differ from the other subspecies found in South Australia, Abultion fraseri ssp. fraseri which have densely tomentose hairs all over the exposed portions of the fruits and mericarps. Flowers in spring. Fruits are brown transversely rectangular capsule to 8.5 mm diameter with up to 10 angles, glabrous or sparsely pilose with simple multicellular hairs. Seeds are dark brown to black covered in scattered hairs. Seed embryo type is folded.
Seed collection and propagation
Collect seeds between October and December. Collect mature capsules, 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 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).
