Members of Sections Clinclinia and Monninopsis, from the New World Clade (NWC) of Polygala, inhabit arid to humid habitats along the American continent. Although knowledge of these sections is currently incomplete, it is crucial for understanding evolutionary and diversification patterns in Polygalaceae. Here, we sample new species from the Polygala NWC with emphasis on these two sections, providing a comprehensive molecular phylogeny based on DNA sequence data from one nuclear (ITS) and three chloroplast (trnL-F intergenic spacer, rbcL, and partial matK-trnK) loci. Furthermore, we conducted comparisons for the main clades in the environmental and geographic spaces using climatic and elevation data processed by ordination and species distribution modelling (SDM) techniques and an ancestral state reconstruction for two morphological flower traits. The study is useful as a first approach to understand the phylogenetic, environmental, and morphological patterns shaping the geographical distribution of the main clades of the sections. The phylogenetic analyses supported at least six distinct lineages within the study group, three in Sect. Clinclinia, and three in Sect. Monninopsis. An updated synonymic list of the Sects. Clinclinia and Monninopsis as treated in this study is also provided.
