This hybrid is accepted
The native range of this hybrid is Medit. It is a tuberous geophyte and grows primarily in the subtropical biome. The hybrid formula is O. fusca × O. omegaifera. (Linkki)
In most countries, Plantago uliginosa is recognized at the species level. If it remains as a subsp. intermedia, people stop determining it because subsp. intermedia no one will differentiate and and all determination will be like Plantago major and no one will be a typical subsp. major distinguish.
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.
