I have been at Chassahowitzka WMA for years. Three years posting my observations on iNaturalist and I don’t recall ever seeing this plant.
The yellow butterwort is listed as a threatened species in the Preservation of Native Flora of Florida Act.
So, this is just a little confusing, no let me say this is confusing about the shapes of these two yellow butterworts.
Hopefully, I am able to get clarification on why the petals have different shapes.
