As a comment about Hen and Chicks (Sempervivum x comollii (x albidum)), banker07 wrote:

this is no cultivar but a natural form; so the cultivarname has to be deleted;

the correct name is S. x albidum or S. x comollii (x albidum);

in the past S. x albidum was seen as an own hybrid-form; later it was declared as a form of S. x comollii which is a natural hybrid of S. tectorum x S. wulfenii;

I think it may be better to change the botanical name to S. x comollii (x albidum) to be different to the "pure" S. x comollii; it's also correct to name it S. x albidum (the older Form);
but only S. x comollii won't show the difference to other S. x comollii which are not albidum;

Which do you think would be the better name to use in current times?

S. x comollii (x albidum)

it's unlikely that 'x albidum' might become a own species again...
