Taxon Framework notes:

iNaturalist follows Plants of the World Online (POWO) for Vascular Plants down to ssp. Caveats are that that POWO only includes info above species on family and genera.

Unfortunately, there appear to be some issues with POWO ferns - read more here https://www.inaturalist.org/flags/271039

Apart from documented deviations, iNat should be curated to match the 'accepted' families, genera, species, hybrids, and infraspecies posted in these archives (which is regularly updated):
