Well, I must say you have studied the genus. Have you seen the pierpoint springs Dudleya? It is so different in both flower and form. Very cool plant. I have seen so many little and big forms of cymosas every color of flower and wide range of leaf forms.....yes very easy to see splitting and lumping and usually directly related to the amount of field work done work. I think the lumping occurs behind desks often without much hiking involved.
