Geographical pattern of isolation and diversification in karst habitat islands: a case study in the Primulina eburnea complex

Aim This study aimed to clarify species boundaries as well as phylogenetic relationships among species of the Primulina eburnea complex, a rapidly diversifying group of edaphic specialists confined to karst habitat islands in southern China. We investigated patterns of genetic isolation and diversification in this complex. Location Limestone karsts in southern China. Methods We analysed data from three chloroplast DNA (cp DNA ) regions and eight...
