03EA5262FF9FFF89FF287AD14C427A33.taxon	distribution	Distribution and proposed conservation status: — Rhabdosciadium hizanense only occurs on the İhtiyarşahap Mountain (Hizan / Bitlis) and can be considered endemic to eastern Anatolia. It represents an Irano-Turanian mountain element. The distribution area of R. hizanense covers less than 20,000 km 2. The species was collected from one locality where about 5000 individuals occur. Some anthropogenic or grazing effects were observed on the population. According to the IUCN (2016) criteria and categories, we here assess R. hizanense as Vulnerable (VU).	en	Firat, Mehmet, Güzel, Yelda (2019): Contributions to the taxonomy of the Irano-Turanian genus Rhabdosciadium (Apiaceae): Nomenclatural notes, carpology, molecular phylogeny and the description of a new species from Bitlis (Turkey).
