Sorry, that was a really bad question I just asked. Let me ask it this way:
Proposal is put forward to:
1) Update all plants to set the genus to 'Plectranthus' (and leave the species as 'scutellarioides') where the genus is 'Solenostemon' and the species is 'scutellarioides'.
2) Of the plants that were updated, then add two synonyms to each of those plants:
Plectranthus amboinicus
and
Solenostemon scutellarioides
Does this look right?
