Step 2: Sabal Palm (Sabal palmetto)/Saw Palmetto Ratio
In the second step, the top 10 logratios either contained sabal palm or saw palmetto. The logratio pair that was therefore selected on the basis of total logratio variance explained – as well as their biological relatedness as palms – was sabal palm/saw palmetto, accounting for an additional 8.57% of the total logratio variance. This logratio was tied for second on the list, only preceded by mouse’s pineapple which only explained 0.02% more of the total variance.
