Two combinations are being used on iNaturalist at the moment for this taxon, which causes confusion and makes it difficult to find all observations of this taxon. Growing consensus, historically dominant usage, and biology favor O. lindheimeri as a species distinct from O. engelmannii, and thus is the favored arrangement followed in this swap. This is contrary to the listing at POWO; however, many sources list O. lindheimeri as a distinct species.
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.
