Phylogenetic studies starting with Pires and Sytsma in 2002 indicated that the genus Dichelostemma was not monophyletic. Specifically, Dichelostemma capitatum (Blue Dicks) is genetically a sister to the clade that includes all the Brodiaea species and the other four species of Dichelostemma. Botanists studying floral morphology had reached a similar conclusion.
I will manually create taxonomic changes for the subspecies because the rules of Latin gender mean that the nominate subspecies name will change its final letter.
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.
