As a result the six new species descended from (I), and the 8 descendants from (A), should be ranked as very designated genera, or maybe as targeted sub-families. hence it really is, as i think, that or extra genera are produced via descent with amendment, from or extra species of a similar genus. And the 2 or extra parent-species are meant to be descended from a few one species of an prior genus. In our diagram, this can be indicated by way of the damaged strains, underneath the capital letters, converging in sub-branches downwards in the direction of a unmarried element; this element represents a species, the intended progenitor of our numerous new sub-genera and genera.
