abstract = {Phylogenetic hypotheses for the large cosmopolitan genus Hypericum (St. John's wort) have
previously been based on morphology, and molecular studies have thus far included only a few species.
In this study, we used 360 sequences of the internal transcribed spacer (ITS) region of nuclear
ribosomal DNA (nrDNA) for 206 species representing Hypericum (incl. Triadenum and Thornea) and
three other genera of Hypericaceae to generate an explicit phylogenetic hypothesis for the genus using
parsimony and model-based methods. The results indicate that the small genus Triadenum is nested in
a clade within Hypericum containing most of the New World species. Sister to Hypericum is Thornea
from Central America. Within Hypericum, three large clades and two smaller grades were found; these
are based on their general morphology, especially characters used previously in taxonomy of the
genus. Relative to the most recent classification, around 60% of the sections of Hypericum were
monophyletic. We used a Bayesian approach to reconstruct ancestral states of selected morphological
characters, which resulted in recognition of characters that support major clades within the genus and
a revised interpretation of morphological evolution in Hypericum. The shrubby habit represents the
plesiomorphic state from which herbs evolved several times. Sclerophyllous treelets have radiated
convergently in high-elevation habitats in tropical Africa and South America.}
