The Vitex trifolia complex of the Philippines

We successfully assembled the complete chloroplast genomes of five species belonging to the Vitex trifolia complex. Based on a detailed analysis of specimens, which combines molecular and morphological data, we propose reinstating V. elmeri Moldenke and delineating V. arvensis Gentallan, Sengun & M.B.Bartolome as a new species belonging to this complex. The new species is a putative hybrid between V. bicolor Willd and V. elmeri Moldenke. We also provided a taxonomic key to identify the five species belonging to the V. trifolia complex in the Philippines.
