Figure 2 Phylogenetic trees and networks showing genetic
relationships among observed ITS ribotypes in (a ) 2016 and
(c ) 2022 and trn L-F and ycf 1b chlorotypes in
(b ) 2016 and (d ) 2022 of Primulina heterotrichapopulations. The relative sizes of the circles in the network are
proportional to the haplotype frequencies, and missing haplotypes are
represented by a small red spot. The frames indicate different clades.
