Pimpinella major (Apiaceae); a New Record for the Flora of Turkey from an Interesting Geography and Contributions to Its Taxonomy

In this study, the distribution of Pimpinella major (L.) Huds. (Apiaceae), which is known to be distributed in Europe and mostly in the European part of Russia, for the first time in the Eastern Anatolian region of Turkey (Bingöl) and some variations of this species arising from the changing ecology are emphasized. In particular, the leaf morphology of the taxon shows many variations; leaf structure features and photographs from basal to uppermost parts were presented. The new record, which is close to P. saxifraga, whose distribution is also known in Turkey; differs from it in that its stem is hollow and angular-deeply furrowed (sulcate). In addition, the characteristics of P. major samples collected from Bingöl were compared with the known diagnostic features of this species and some differences were emphasized.
