Hibbertia prostrata cf. Hibbertia fasciculata, s.l, s.s. and var. prostrata – In the context of Vic. .– for what iNat 'taxonomy' is worth.

English language paraphrases from the original species descriptions publications – of the differences, in their authors' terms :

Hibbertia fasciculata R.Br. ex DC. (1818)
• mature leaves glabrous,
• stems erect and branching, hairy,
• styles subdiverging
https://www.biodiversitylibrary.org/page/41046603
.

Hibbertia prostrata Hook. (1834)
• mature leaves hairy,
• stems decumbent–procumbent, hairy,
• single style (apparently – was thought and thought a single carpel, – at the time of description).
https://www.biodiversitylibrary.org/page/796127
.
Hibbertia fasciculata var. prostrata (Hook.) Hook.f. (1860)
https://www.biodiversitylibrary.org/page/28465113
.

In this context of Vic. .– for what iNat 'taxonomy' is worth.

I'm not surprised people have confusion about this, both professional botanists and citizen scientists into plants (amateurs).

Different concepts of the taxa: Hibbertia fasciculata and Hibbertia prostrata,
here especially Hibbertia fasciculata var. prostrata, and other infra-specific taxa, are used by each of the:
• Australian Plant Name Index (APNI) – Australian Plant Name Census (APC).
• Flora of Vic. online VicFlora
• Tasmanian herbarium
• Flora of NSW
• iNaturalist volunteer 'curated' 'taxonomy'
• POWO
• etcetera .

References:

• Flora of Vic. online VicFlora:
Hibbertia fasciculata var. prostrata page, quotation: "

The anthers are longer, flowers larger and habit more robust than in the type variety, Hibbertia fasciculata var. fasciculata, which is restricted to New South Wales. Despite the varietal epithet ('prostrata'), the plant is rarely, if ever, truly prostrate in Victoria.

VicFlora conferred with iNat, spelling it out about the taxa concepts:

Hibbertia fasciculata var. prostrata in the sense of VicFlora (taxon concept)
has equivalence to Hibbertia prostrata in the sense of iNat's species 'taxon concept'.

Hibbertia fasciculata var. fasciculata in the sense of VicFlora (taxon concept – and only occurs in NSW and Qld)
has equivalence to Hibbertia fasciculata in the sense of iNat's species 'taxon concept', and only occurs in NSW and Qld.

Hibbertia fasciculata var. prostrata has no equivalence to Hibbertia fasciculata var. fasciculata (in any accurate botanical information).

• The taxon concept of Hibbertia prostrata has no equivalence to Hibbertia fasciculata types' specimens' based narrow sense taxon concept (in any accurate botanical information).

Hibbertia fasciculata types' specimens' based narrow sense taxon concept
differs from Hibbertia fasciculata types' specimens' based broad sense taxon concept.

Hibbertia fasciculata var. prostrata and Hibbertia prostrata mutually equivalent in types' specimens' based taxon concept,
do not have identity equivalence to Hibbertia fasciculata types' specimens' based broad sense taxon concept and again saying,
also do not have equivalence to Hibbertia fasciculata types' specimens' based narrow sense taxon concept.
