If, in the diagram, we suppose the amount of change represented by each successive group of diverging dotted lines to be great, the forms marked a14 to p14, those marked b14 and f14, and those marked o14 to m14, will form three very distinct genera.
Baldin diagraman puntuzko lerro dibergenteen hurrenez hurreneko lerro bakoitzak irudikaturiko aldaketa kopurua handia dela jotzen badugu, o14-tik p14-rako, b14 eta f14 eta o14-tik m14-rako formek hiru genero oso bereizi eginen dituzte.
