Fig. 3From: Evolutionary histories determine DNA barcoding success in vascular plants: seven case studies using intraspecific broad sampling of closely related speciesSequence networks drawn for selected DNA barcode(s) within each genus. Each unique sequence combination is represented by a circle, with size proportional to the number of individuals sharing the sequence. Each branch segment represents a single mutation; substitutions are coded as full lines and indels as double linesBack to article page
