sequences of nuclear ribosomal DNA.
The phylogeny of the Campanulaceae as inferred from ITS sequences of
almost 100 taxa comprising the majority of genera reveals a division
of the family into two major clades. The basal clade consists of
tropical and Asian taxa of the platycodonoid alliance. The other clade
consists of wahlenbergioid taxa of the southern hemisphere and
campanuloid taxa of the northern hemisphere. These results are
consistent with pollen data and are remarkably congruent with data
from genome rearrangements and sequences from several chloroplast
genes. The topology of the campanuloid clade suggests that large
genera such as Campanula are not monophyletic .
