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!
