Hi - It is getting more and more obvious that you are going to have to split up 'English' common names into their various principalities - such as American, Canadian, British, South African, Australian 'English' etc. etc. because in this case 'Spreading' Fescue has no meaning in the UK flora at all! And Fescues and Rye Grasses have been previously been regarded as a separate genus to each other - but that's yet another taxonomist's problem to justify
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.
