Orobanche owerini (Beck) Beck is reported as a new record to flora of Turkey for the first time, and the existence of O. reticulata Wall. that was mentioned as a doubtful record for Turkey has been confirmed. Macro- and micromorphology of the taxa are discussed, geographical distributions in Turkey are mapped, and details of their habitat, ecology, and taxonomic remarks of the studied taxa are provided. Key words: New record, Orobanche, Orobanchaceae, taxonomy, Turkey 1. Introduction Orobanche L. . (including Phelipanche Pomel) is the largest genus among the holoparasitic members of Orobanchaceae. It is mainly distributed throughout the subtropical and temperate regions of the northern hemisphere, and the Mediterranean region is one of the most important centres of its diversity (Plaza et al., 2004). Due to the changing of diagnostic characters on dried plant materials and lack of adequate field notes on herbarium sheets, taxonomy of the genus Orobanche has been difficult and it is more problematic than that of most other taxa. The distinct colours of the Orobanche species in the field turn into a uniform brown after pressing. Problematic identification keys in the floras and insufficient distribution data have led to a high number of misidentifications. Taxonomy and distribution of Orobanche . in Turkey still rely on Gilli’s treatment (1982), which is only based on herbarium materials and previous bibliographic .
