Complex Biogeographic Patterns in Androsace (Primulaceae) and Related Genera: Evidence from Phylogenetic Analyses of Nuclear Internal Transcribed Spacer and Plastid trnL-F Sequences
We conducted phylogenetic analyses of Androsace and the closely related genera Douglasia, Pomatosace , and Vitaliana using DNA sequences of the nuclear internal transcribed spacer (ITS) and the plastid trnL-F region. Analyses using maximum parsimony and Bayesian inference yield congruent relationshi...
