I’m the person who added the common names for the three new taxa in question, but I didn’t make them up. I documented my sources in wikipedia:
I think calling the above species “heart-leaved foamflower” in the iNat taxonomy is a very bad idea since that name already belongs to Tiarella cordifolia. I’m sure state and regional floras will continue to refer to “heart-leaved foamflower” for a long time to come, and of course that’s just fine.
