Phylogeny and dating of Aframomum (Zingiberaceae)

A phylogeny of the African genus Aframomum (Zingiberaceae) is presented based on nuclear ribosomal DNA ITS and plastid trnL-trnF DNA sequences. parsimony and Bayesian analyses were performed on both independent and combined data sets, which were obtained by adding new sequences to already published...
