Critical taxonomical notes on poorly known Johrenia porteri Post ex Boiss. (Apiaceae)

Abstract

Yavuz Bagci and Muhittin Dinc*

In addition to the incomplete type from Turkey, Johrenia porteri Post ex Boiss. is known from only two herbarium specimens of doubtful systematic position from Turkey-Syria border. The deficiencies in both type and other herbarium samples have been caused uncertainty and debate about the taxonomic position of the species. In this article, Johrenia porteri is epitipified and its taxonomic position has been clarified. The description of the species has been expanded with the studies conducted within the scope of the samples collected in different developmental periods from the type locality as well.
