de Lange, P.J. et al. 2015: Senecio esperensis (Asteraceae: Senecioneae)—a new combination for the L'Esperance Rock groundsel, Kermadec Islands. New Zealand journal of botany, doi: 10.1080/0028825X.2015.1039552 [See p. [2]; 'Senecio esperensis (Sykes) de Lange comb. et stat. nov.']
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.
