Name derivation:
Hibbertia named after George Hibbert (1757-1837), a London merchant who maintained a private botanic garden at Chelsea. fasciculata from the latin fasciculus meaning fascicle or bundle; referring to the lateral branches.
Distribution:
Found on Kangaroo Island and in the South-east in South Australia, growing on sandy soils in heathland, heathy woodland and mallee communities. Also found in Queensland, New South Wales, Victoria and Tasmania.
Status:
Native. Uncommon in South Australia. Common in the other states.
Plant description:
Spreading to decumbent shrubs with usually glabrous branches to 0.5 m long, lateral branches usually fascicled, covered with forward-directed straight or crisped simple hairs. Leaves linear, to 21.4 mm long and 0.7 mm wide, glabrous, puberulous or rarely tomentose, apex obtuse, erect to somewhat incurved, margins often incurved, lower surface usually strongly convex with central vein not showing. Flowers bright yellow, sessile, terminal, mainly on short shoots, with 2 triangular bracts. Flowering between September and December.
Fruit type:
Brown capsule with 3 carpels, glabrous. 
Seed type:
Brown, globular seed to 1.6 mm diameter.
Embryo type:
No information available
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. From one collection, the seed viability was low, at 30%.
Seed germination:
This species has morphophysiological dormancy and can be difficult to germinate.
