Scorzonera incisa (Asteraceae), as a new record from NW Iran

Scorzonera incisa, known as an endemic plant to Turkey, has been collected from West Azarbayejan Province, NW. Iran. The species is reported for the first time from the country; it is very similar to Scorzonera calyculata, which is distributed in the western half of Iran and east of Iraq. However, with regard to the particular shape of the achenes of Scorzonera incisa, this species could be separated from Scorzonera incisa. In this paper, the description, the image of the herbarium sample and the distribution map of this species are presented.
