Arctous alpina and Arctous rubra are two North American species of the genus Arctous that have been held up in recent molecular phylogenies as distinct from the genus Arctostaphylos. The genus is also accepted in Flora of North America, and Plants of the World Online.
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.
