abstract = {The phylogeny of baobab trees was analyzed using four data sets: chloroplast DNA restriction-sites, sequences of the chloroplast rpl16 intron, sequences of the ITS region of nuclear rDNA, and morphology. We sampled at least one accession of all eight species of Adansonia plus three outgroup taxa from tribe Adansonieae. These data were analyzed singly and in combination using parsimony. ITS and morphology provided the greatest resolution and were highly concordant. The two chloroplast data sets showed concordance with one another but disagreed with ITS and morphology. This disagreement was found to be significant using a Wilcoxon sign-rank test and an incongruence length difference test. The most likely explanation of the conflict is genealogical discordance within the Malagasy Longitubae, perhaps due to introgression events. A maximum-likelihood analysis of branching times shows that the dispersal between Africa and Australia occurred well after the fragmentation of Gondwana and, therefore, involved over-water dispersal. The phylogeny does not permit unambiguous reconstruction of floral evolution, but suggests the plausible hypothesis that hawkmoth pollination was ancestral in Adansonia and that there were two parallel switches to mammal-pollination in the genus.
