| Phylogenetic relationships among Chilean species of Drimys as well asD. granadensis from Central America andD. angustifolia from Brazil were reconstructed using internal transcribed spacers (ITS) of nuclear ribosomal DNA and a parsimony analysis. Our results at the family level were congruent with previous phylogenetic hypotheses. Molecular data indicate that the Juan Fernandez Island endemic D. confertifolia diverged early in the evolution of the genus, and it is not closely related to the continental species D. winteri, as might be expected on the basis of morphology and biogeography. The ITS phytogeny also provides general support for a recent distribution of species on the western side of the Andes Mountains; the only exception is D. andina, which may... |
