Phylogenomics, historical biogeography, and diversification of leaf traits in the Malagasy‐endemic genus <i>Uncarina</i> (Pedaliaceae)

As with Malagasy lemurs and other animals, riverine barriers may have been involved in the diversification of Uncarina and may apply more broadly to epizoochorous angiosperms of Madagascar. Leaf traits suggest either a loss of adaptations to extremely arid, high irradiance environments or a release from herbivores. As is likely needed in other Malagasy lineages, more thorough population-level sampling and specimen collecting is needed to fully understand the taxonomic and morphological diversity in the genus.
