This treatment of the group deviates from the version in Plant of the World Online which is based on an older treatment of Lupines that favors splitting these taxon into many species, subspecies, and varieties. Further revision may be necessary following the publication of the Flora of North America volume that covers this genus (10 or 11).

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.
