Phylogenetics of <i>Ochna</i> (Ochnaceae) and a new infrageneric classification

Abstract Advances in high-throughput DNA sequencing are allowing faster and more affordable generation of molecular phylogenetic trees for many organisms. However, resolving relationships at species level is still challenging, particularly taxonomically difficult groups. Until recently, the classification Ochna had been based only on morphological data. Here, we present first comprehensive phylogenomic study genus using targeted with a custom probe kit. We sampled c. 85% to evaluate current infrageneric classification. Our results show that data generated kit effective genus, revealing three sections consistent new section consisting from Madagascar Mascarene Islands. provide insights into evolutionary several widespread morphologically diverse numerous poorly known potentially science. demonstrate challenging groups such as Ochna, an integrated approach essential. Phylogenomic informative when derived accurately named samples. There symbiotic relationship between phylogenomics morphology-based taxonomy, taxonomic expertise requirement interpret results.
