Echeveria gibbiflora is one of the most hybridized plants in the genus. Responsible for almost all the carunculated plants (this feature is age dependent, not consistent generally, somewhat unpredictable in some plants). Also the ruffled phenotype of plants like Mauna Loa. There are many hybrids, including complex hybrids, by Dick Wright (Rain Drops is a derivative). I think you will need to see the adult full size plant (including its flowers) before you reach any real conclusions.
