Name derivation:
Hibbertia named after George Hibbert (1757-1837), a London merchant who maintained a private botanic garden at Chelsea. Crispula from the Latin 'crispus' meaning sinuous or curly, wavy; referring to  the  curly hairs on the inner side of the leaf-base.
Distribution:
Endemic to South Australia and found in two locations around Ooldea and Lake Everard, growing on red sand.
Status:
Native. Rare in South Australia.
Plant description:
Small wiry shrub, glabrous except for a minute curly tomentum on the inner side of the leaf-base, to 50 cm high. Leaves terete, sometimes clustered, to 45 mm long and 1 mm wide, 1-furrowed above by the incurved margins. Flowers yellow, large, sessile or rarely shortly pedunculate. Flowering between August and September.
Fruit type:
Brown ovoid capsule with 3 carpels and 4-6 ovules in each, glabrous.
Seed collecting:
Collect mature capsules, those that are turning a pale straw colour and contain brown seeds.
Seed cleaning:
Place the capsules in a tray and leave to dry for one to 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.
Seed viability:
This genus tend to have low seed viability.
Seed germination:
This species has morphophysiological dormancy and can be difficult to germinate.
