The need for species identification and taxonomic discovery has led to the development of innovative technolo... ...hologically and subject to next-generation DNA sequencing in the diverse and recently radiated neotropical genus, Inga (Leguminosae), both at single study sites and across broad geographic scales. Our results show that chemocoding is a robust method for distinguishing morphologically similar species at a single site and for identifying widespread species across continental-scale ranges. Given that species are the fundamental unit of analysis for conservation and biodiversity research, the development of accurate identification methods is essential. We suggest that ...
