Article
The aim of the present study was to analyse the support for reducing Chaerophyllum karsianum and C. posofianum, both local endemic to northeast Anatolia, to synonyms of C. bulbosum. Chaerophyllum karsianum is closely related to C. bulbosum but may be distinguished from it by its pink petals, ciliate bracteoles, entire leaf segments and 12–16 rays....

Oliveria is a little-known, monotypic genus of the family Apiaceae. The only accepted species, O. decumbens, is distributed throughout Mesopotamia. It is an annual, aromatic plant that has been used in traditional medicine since ancient times. The aim of this study was to examine morphological, micromorphological, and anatomical characters of O. de...

A phylogenetic study of the Opopanax and Crenosciadium was conducted to elucidate their circumscription and infrageneric relationships. Sequence data from nrDNA ITS, cpDNA matK and trnL-F were used to determine their phylogenetic relationship. Polymerase Chain Reaction (PCR) amplifications of all regions were performed using universal primers. Maxi...

Taxonomic descriptions of Iranian and Turkish Hesperis (Brassicaceae) species are generally insufficient and partly incomplete , which makes the species delimitation ambiguous. In order to clarify species circumscription, we scored 57 morphological descriptors (MDs) in 121 operational taxonomic units (OTUs) of Hesperis from Iran and Turkey and perf...
