Phylogenetic and Biogeographic Diversification of Berberidaceae in the Northern Hemisphere

Sequences of the chloroplast genes matK and rbcL and nuclear ribosomal ITS2 were used for phylogenetic analyses of Berberidaceae. Three major clades were recognized, corresponding to the chromosome base numbers x = 6, 7, and 8/10. Bongardia was sister to the clade containing Achlys and the Podophyll... View More
