The Hieracium study group developed from an international collaboration (first taxonomic contacts in 1992, addition of molecular and cytological approaches (1997 & 1998), joint projects and presentations began in 1999), and was finally established in 2002 as an interdisciplinary research team within the Institute of Botany, Academy of Sciences of the Czech Republic.

Our principal aim is to contribute to the understanding evolutionary processes in the genus Hieracium sensu lato.
