Epilobium and Chamaenerion included 165 and 8 species over the world, respectively. The members of the genera are distributed particularly in moist habitats from subpolar to tropical regions. This paper aims to provide improvements in the phylogeny of the genera Epilobium and Chamaenerion using Internal Transcribed Spacer (ITS) of nuclear DNA and matK gene sequence data evaluation with maximum parsimony, maximum likelihood, and Bayesian inference criterations. A total of 188 individual accessions belonging to 28 taxa were newly generated and 110 sequences imported from GenBank (NCBI) were analysed. The nrDNA and plastid DNA gene trees supported to treat Epilobium and Chamaenerion as separate genera in two well-supported clades. The matK analyses revealed a better resolution than nrDNA ITS within the Chamaenerion clade and supported the inclusion of C. angustifolium in the sect. Chamaenerion. However, most of the examined species mostly fell into the polytomy in both trees excluding E. roseum subsp. consimile which should be considered a distinct species in the Epilobium contrary to morphological treatment in many national flora books. Both phylogenetic trees also support distinguishing E. prionophyllum from E. anatolicum previously treated as a subspecies of E. anatolicum. In conclusion, these preliminary phylogenetic analyses have contributed significantly to the determination of the limits of members belonging to Epilobium and Chamaenerion distributed in Türkiye.

This paper presents a taxonomic contribution to the genus Pyrus L. P. georgica and P. pseudosyriaca are reported from Turkey for the first time. The status of P. pseudosyriaca is discussed and it is treated as a new variety of Pyrus syriaca. Notes on the chorology, morphological descriptions, figures, and taxonomy are provided. Moreover, P. serikensis and P. boissieriana are reduced to synonyms of P. cordata. An endemic subspecies, P. elaeagrifolia subsp. kotschyana, is compared with the related species P. elaeagrifolia and it is reassessed at the species level based on morphology and distribution. With these changes, Pyrus is represented by 18 taxa belonging to 12 species in Turkey. [ABSTRACT FROM AUTHOR]

Minuartia turcica M.Koç (Caryophyllaceae) is described as a new species of sect. Minuartia. The specimens were collected from the village of Yukarıçiftlik in the district of Safranbolu (Karabük Province, Turkey). The new species is similar to Minuartia leucocephaloides, but the differences between the 2 species are discussed in this paper. Descriptions and illustrations are given, as is information on the distribution and conservation status of the new species. [ABSTRACT FROM AUTHOR]

The fourth check-list of the series entitled "Additional taxa to the Flora of Turkey" comprises a total of 175 taxa based on data given in 162 papers published up until the end of 2007. It provides details of taxa not recorded in the 11 volumes of the Flora of Turkey and the East Aegean Islands nor in the there previously published supplementary check-lists. [ABSTRACT FROM AUTHOR]

Ferula parva Freyn & Bornm. was first collected from Central Anatolia (Turkey B5 Kayseri-Yozgat in declivibus apricis inter Kayseri et Yozgat, 1890) by Bornmuller. No specimens belonging to this species have been collected since the type and Andrasovszky specimens. When the Flora of Turkeywas being prepared, Dr. H. Peşmen considered this species imperfectly known; therefore, it was not included in the keys. In the present paper, diagnostic morphological characters are discussed. In addition, its ecology, conservation status, SEM photographs of the surface of mericarps, and chromosome numbers are presented. [ABSTRACT FROM AUTHOR]

This paper describes a floristic study of Bozburun Mountain and its environs. The study was conducted between 1998 and 2002, during which time 2419 vascular plant samples were collected. After the identification of the specimens, the total flora was determined to consist of 645 taxa belonging to 341 genera and 86 families. The endemism rate of the 645 taxa was 16.1% (n = 104 taxa). The phytogeographical spectrum of the species was as follows: Mediterranean 207 (32.1%), Irano-Turanian 51 (7.9%) and Euro-Siberian elements 33 (5.1%). Of the species we sampled, 311 (48.2%) were widespread and the phytogeographical regions of 10 (1.5%) were unknown. [ABSTRACT FROM AUTHOR]
