Integrating datasets from herbarium specimens and images to treat a Neotropical myrtle species complex.

ABSTRACT:

Background and aims

Herbaria are the most important source of information for plant taxonomic work. Resources and technologies available today, such as digitized collections and herbarium DNA sequencing, can help accelerate taxonomic decisions in challenging plant groups. Here we employ an integrative methodology relying exclusively on herbarium specimens to investigate species boundaries in the Neotropical Myrcia neoobscura complex (Myrtaceae).

Methods

We collected morphometric data from high-resolution images of herbarium sheets and analysed them using hierarchical clustering. We posteriorly tested the obtained morpho-groups with phylogenomics using the Angiosperms353 probe kit. We also gathered phenological and geographical information from specimen labels and built pheno
