Key Points

The aim is to identify four buttonweed accessions common in Brazil's agricultural areas and classify them using molecular methods.
Seeds collected and cultivated in both greenhouse and field conditions.
Plants were grown until transplantation in field settings.
Molecular analysis conducted for species identification.
Four buttonweed accessions were successfully identified.
Molecular analysis provided a clear distinction between the species.
Characterization supports better management of buttonweed in agricultural practices.
