Table 1 Results of Kruskal Wallis analyses of island age over genetic diversity for three datasets: whole archipelago, M. hyssopifolia and taxa belonging to the M. varia complex; and taxa belonging to the western lineage (Tenerife, La Palma and El Hierro and M. pedro-luisii from La Gomera)

From: Genetic diversity and differentiation patterns in Micromeria from the Canary Islands are congruent with multiple colonization dynamics and the establishment of species syngameons
