title: Arabis watsonii(P.H.Davis) F.K.Mey.: An overlooked cruciferous species from eastern Anatolia and its phylogenetic position.
abstract: Arabis watsonii(P.H.Davis) F.K.Mey. was initially reported asThlaspi watsoniiP.H.Davis in Flora of Turkey. Although F.K.Meyer transferred this species toArabisL., this species has been overlooked and treated asThlaspiL. in relevant literature for Flora of Turkey. In this study this species was evaluated using molecular (nuclear ITS and plastidic trnL-F sequences) and morphological data. Results clearly show thatArabis watsoniiis sister to theArabis hirsutaaggregate and its relatives. In conclusion, our results increased the number of knownArabisspecies in Turkey to 23. Furthermore, detailed description and distribution of the species are given and a new IUCN threat category forArabis watsoniiis proposed.
