Aethionema erzincanum sp. nova (Brassicaceae) is described from Erzincan Province in Turkey. It is morphologically close to A. speciosum, but its leaves are succulent, flowers white with a pink mid-vein, and pedicels are erect at fruiting stage. We provide information on the pollen and seed structure and habitat, and a species distribution map.

Pastinaca erzincanensis Menemen & Kandemir (Apiaceae) is described as a new species, restricted to a single location in Erzincan Province, Turkey. To describe the species and assess its phylogenetic placement, field-collected and herbarium specimens were examined for morphological, fruit anatomical/micromorphological and palynological variation and included in a molecular phylogenetic study. Comparisons of leaf morphology, palynology and fruit anatomy suggest an affinity with Pastinaca (Tordylieae tribe Tordyliinae), although the presence of vittae in the fruit ribs is unique within the genus. Maximum parsimony and maximum likelihood analyses of nrDNA ITS sequences from representative members of tribe Tordylieae show that P. erzincanensis nests within a well-supported clade comprising members of Pastinaca, Malabaila and Trigonosciadium. Within a poorly supported Pastinaca s. lato clade, P. erzincanensis is sister group to M. pastinacifolia, with P. pimpinellifolia, P. yildizii and M. brachytaenia placed as successive sister taxa. Pastinaca erzincanensis differs from M. pastinacifolia, P. pimpinellifolia, P. yildizii and M. brachytaenia by having nine vittae on its dorsal mericarp surface (four vallecular and five rib vittae) and no commissural vittae. Based on characters of leaf morphology, palynology and fruit anatomy, and the molecular phylogenetic analysis results, we recognize the new species as belonging to the genus Pastinaca.

A new species Jurinea kemahensis B. Dogan, Kandemir and A. Duran (Asteraceae) is described from East Anatolia, Turkey. It grows in calcareous crevices in the Kemah district (Erzincan province) in the East Anatolia. It is morphologically fairly similar to J. tortumensis, and its diagnostic morphological characters are discussed the ecology and distribution of J. kemahensis are also presented the pollen characteristics and achene surface of J. kemahensis and J. tortumensis were examined by SEM.
