Abstract The Marantaceae (∼530 spp.) are one of the most species rich families within the order Zingiberales which incites the search for evolutionary factors favoring speciation. A positive influence on their divergence is ascribed to their unique explosive pollination mechanism which has been proposed to be a key innovation. To test this hypothesis phylogenies of the two major African clades (Sarcophrynium and the Marantochloa clade) were established based on data from nuclear (ITS, 5S) and chloroplast (trnL/trnL-F) DNA for an almost complete taxon sample. The phylogeny was used to parsimoniously reconstruct morphological and ecological traits and geographic distribution patterns. The resulting molecular relationships of the genera are congruent with the existing family phylogeny. As in previous studies the species Ataenidia conferta is nested within Marantochloa so that a new circumscription of Marantochloa is proposed leading to the new name Marantochloa conferta . Hybridization events, adaptation to ...
