Intra- and interspecific genetic distances of barcoding genes acrossViburnum. Histograms showing intraspecific (black bars) and interspecific (green bars) genetic distances calculated using a K2P model of sequence evolution for each gene region or combination of gene regions. Each histogram contains the name of the gene region or regions sampled and a black vertical line indicating the mean genetic distance for the gene region(s).
