Data from: Phylogenetic relationships among members of the neotropical clade of Miliuseae (Annonaceae): generic non-monophyly of Desmopsis and Stenanona

The phylogenetic relationships among members of the Neotropical clade of
Miliuseae were inferred using Bayesian inference, maximum likelihood, and
parsimony on a dataset of six plastid regions (ndhF, matK, psbA-trnH,
rbcL, rps16-trnQ, and trnL-F). The phylogenetic hypothesis obtained
indicate that the Neotropical clade of Miliuseae is a monophyletic group,
composed of two distinct lineages: the first comprises the genera
Sapranthus and Tridimeris, and the second is composed of Desmopsis,
Stenanona, and two potentially new taxa, which together form the
Desmopsis-Stenanona clade. However, the relationships within the
Desmopsis-Stenanona clade are not fully resolved; the phylogenetic results
indicate that Desmopsis and Stenanona, as currently circumscribed, are not
monophyletic. The morphological characteristics that distinguish each
genus and potential synapomorphies are discussed. We conclude that the
observed variation in floral and fruit characteristics among the members
of the Desmopsis-Stenanona clade could be driven by interactions with
their main pollinators and fruit dispersers. Based on these results we
propose that the Neotropical clade of Miliuseae needs to be recognized at
the subtribe level, under the name of Sapranthinae.
