"Kitchingia" is now regarded as a synonym for "Kalanchoe", while "Bryophyllum" has also been treated as a separate genus, since species of "Bryophyllum" appear to be nested within Kalanchoe on molecular phylogenetic analysis, "Bryophyllum" is considered as a section of the former, dividing the genus into three sections, "Kitchingia", "Bryophyllum", and "Eukalanchoe".
