Jo, Of course you are right about that. The best thing might be if the knowledgeable cyclamaniacs - who are the only people likely to be using the very latest names - made sure that they listed any aliases in general use at the same time. For instance, as you know, Kew reckon that the correct name for what has recently been called
Cyclamen rhodium is still
C. repandum subsp.
rhodense, while they reckon similarly that
Cyclamen rhodium subsp.
vividum should still properly be called
Cyclamen repandum var.
vividum. I don't think it matters which names are used here, but it would help if people using the latest names, that haven't yet won Kew approval, at least mentioned the more familiar ones at the same time. (I'd prefer that to simply citing the authority for the particular name being used, which would be another way of getting around the difficulty but would probably entail too much reference-checking for most of us. And on this forum at least one member took the authority name to be a cultivar name
)
Another thing that would be really helpful would be a list of the various recent and less familiar names, with a translation beside them of their more generally known Plant List names. The list should include the rhodiums, of course, plus crassifolium, confusum etc. Would you like to do that for us, Jo?
