Abstract
Holoparasitic genera within the family Orobanchaceae are characterized by greatly reduced vegetative organs;
therefore, molecular analysis has proved to be a useful tool in solving taxonomic problems in this family. For
this purpose, we studied all species of the genera Orobanche and Phelipanche occurring in Central Europe,
specifically in Poland, the Czech Republic, Slovakia, and Austria, supplemented by samples mainly from Spain,
France, Germany, and Ukraine. They were investigated using nuclear sequences (ITS region) and a plastid trnLtrnF
region. The aim of this study was to examine phylogenetic relationships within Orobanche and Phelipanche
from Central Europe; we focused on problematic species and aggregates, recent taxonomic changes in these
(rank and secondary ranks), and host ranges. The most interesting results concern the exlusion of O. mayeri
from O. alsatica aggr. Additionally, following the rules of traditional taxonomy, the correct names and types of
some secondary ranks are given and, as a result of this, a new combination below the Phelipanche genus is made
(P. sect. Trionychon). The host ranges of the investigated species in Central Europe include 102 species from 12
families, most often from Asteraceae. For this purpose, ca. 400 localities were examined in the field. Moreover,
data acquired from the literature and European and Asian herbaria were used.
