Tacitus bellus

I have a hard time changing the name on this one. I know the consensus is that it should be transferred to Graptopetalum (as bellum), but maybe I'm just getting too old to change.
But, no, I know that's not true; most regularly I adapt to change quite well. I guess I just like the sound of Tacitus. Arrest me!
With a flower like this, who cares anyway...

Graptopetalum bellum (AKA Tacitus bellus)

We've always known this as Tacitus bellus but it appears the name Graptopetalum bellum is winning out. It's too bad; I really like the former name much better. No scientific reason...just like it! Tacitus is a monotypic genus, with bellus as it's only species. It differs from the other Graptopetalum by its large flowers that have lips around the carpels. O well, the lumpers appear to have won again!
