Our plants in New England, which we previously treated as a variety of S. humilis, are being "corrected" to S. caroliniana, but this appears to be in error. As near as I can tell, the best current taxon for them on iNaturalist would be S. humilis var. tristis.
Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
