Data from: Phylogenomics and generic limits of Dypsidinae (Arecaceae), the largest palm radiation in Madagascar

<p>With 178 species, the palm subtribe Dypsidinae is one of the largest plant radiations on Madagascar. A well-resolved species-level phylogeny is required not only to unpick the drivers of this spectacular radiation but also to define natural and useful generic limits in this taxonomically difficult group. The only recent taxonomic revision of Dypsidinae recognized just four genera, including the large genus <em>Dypsis</em> (currently with 172 species), which was considered impossible to divide further based on morphology alone. Here we describe the first comprehensively sampled species-level phylogeny of Dypsidinae, including 157 described species (88% of the subtribe) as well as 10 samples of uncertain taxonomic identity (potential new species). Our tree is based on target sequence capture data for 161 nuclear DNA loci. The phylogenetic relationships recovered render <em>Dypsis</em> s.l. paraphyletic, requiring the resurrection of two previously synonymised genera. In total, we recognize six genera in Dypsidinae (<em>Dypsis</em> Noronha ex Mart., <em>Chrysalidocarpus</em> H.Wendl., <em>Marojejya</em> Humbert, <em>Vonitra</em> Becc., <em>Lemurophoenix</em> J.Dransf., and <em>Masoala</em> Jum.), all of which are monophyletic and consistent with morphology.</p>
