Taxonomical and Chorological Notes on the Turkish Endemic Scorzonera amasiana Hausskn. Bornm. (Asteraceae)

Scorzonera amasiana Hausskn. Bornm. is a stenoendemic species known from a few localities in Amasya Province. After the rediscovery of S. amasiana, it has been recorded from a new locality in Amasya. Using chorological and ecological data,morphological study of the collected specimens suggest that the recently described Scorzonera ekimii A.Duran is synonymous with S. amasiana. The conservation status of S. amasiana is also reviewed, based on the present distribution data.
