Physaria globosa (Desv.) O'Kane & Al-Shehbaz is a federally endangered mustard that grows in Tennessee, Kentucky, and Indiana. The pollinator communities for this species are poorly understood across its range, with only one previous study that documented six effective pollinators from a population in Tennessee. A complete understanding of pollinator diversity associated with any rare plant species is foundational data needed for recovery and long-term success. Floral visitors were captured and effective pollinator species were identified across the range of P. globosa from 2021-2023. To detect additional floral visitor species that might otherwise be missed through traditional sampling efforts, environmental DNA (eDNA) metabarcoding was assessed as a supplemental method. Floral visitor eDNA was extracted from both fresh flowers and preserved herbarium specimens of various angiosperm species to detect contemporary and historical plant-animal interactions. From herbarium specimens, animal taxa from 29 clades including birds, moths, bees, and many "intrafloral invertebrates" were identified from specimens up to 69 years old. The age of the specimens used for metabarcoding analysis did not significantly affect the amount of detectable eDNA present in each sample. Traditional floral visitor surveys revealed 48 effective pollinator species for P. globosa across 14 genera of bees and flower flies. Twenty bee species, including 13 species from effective pollinator genera were detected through eDNA metabarcoding of P. globosa flowers. The majority of taxa detected through eDNA metabarcoding were small or cryptic invertebrates that were missed during floral visitor collections. These results indicate eDNA metabarcoding may be an effective supplement to traditional floral visitor surveys and can be used to detect historical plant-animal interactions in the future.
