Figure 5

Bar plot of assignment proportions of individual plants (1–72) from the Structure analysis.
Individual plants were morphologically identified as Rumex obtusifolius (1–21), R. longifolius (22–51) and the hybrid (52–72). The length of each bar reflects the Bayesian posterior probability that the 72 individuals belong to R. obtusifolius (light shaded part) and R. longifolius (dark shaded part).
