@bouteloua Thanks for the additional info regarding ferns. I'm reading through https://www.inaturalist.org/taxa/121943/taxonomy_details and https://www.inaturalist.org/flags/271039 now
Generally I try to follow PPG I (aside from some areas like filmy ferns and Blechnaceae where I'm trying not to cause chaos in New Zealand), but World Plants/Ferns (Michael Hassler's site) does a pretty good job of keeping up with new changes in the literature since the publication of PPG I. He also goes down to species level, which PPG I doesn't, and pteridoportal.org uses a slightly modified version of his taxonomy, so it's usually a good guide to align by. There are definitely still some errors to be threshed out, and I periodically correspond with Michael to get them updated.
In this particular case, I remember that some typification issues have come to light in Azolla, where the commonly used circumscription of one name didn't actually correspond with the type material. Let me dig a bit and see what the current state of play is.
OK, this looks sound--Reid et al. 2006 established that these two taxa were conspecific, and microphylla is the senior epithet. Looks like Pereira might describe a new species or two one of these days, but all the morphological characters are microscopic. Most of our observations should be capped at genus level, frankly.
Thanks @choess
@choess can you take a look? Is World Ferns the new recommended authority for ferns? https://www.worldplants.de/world-ferns/ferns-and-lycophytes-list#1609371404
@gcflora we're apparently using PPGI for ferns, not Plants of the World Online, but that only goes to genus.
