Astragalus silifkeense Dinç, Aytaç & Doğu, sp. nov. (Fabaceae, sect. Astragalus Bunge) is described as a new species from Silifke (Mersin Province), in southern Anatolia, Turkey. The new species is closely related to A. columnaris Boiss., endemic to Denizli in western Anatolia, and A. gilvus Boiss. in Ankara Province, Turkey. Taxonomic descriptions, as well as pollen and seed characters of the new species, are presented. The new species grows in an open Abies cilicica (Antoine & Kotschy) Carrière forest. The geographical distribution of the new species, along with that of A. columnaris and A. gilvus, is shown. The new species is compared with is relatives A. columnaris and A. gilvus.

“…It is also the largest genus in Turkey where it is represented by 400 species in 62 sections (Chamberlain and Matthews, 1970;Adiguzel et al, 2006). A great many of Astragalus species spread out the steppe regions of Turkey, where they show adaptation to the high mountain steppes Akan et al, 2008). Some of these Astragalus species are used in traditional medicine for the treatment of various diseases -for example, diabetes mellitus, nephritis and leukemia (Tang and Eisenbrand, 1992;Avunduk et al, 2008)because of their antioxidant activities that protect cells against the damage of free radicals (Yu et al, 2005a;2005b;Li et al, 2006;Yin et al, 2006) and biological activities such as antiviral, antibacterial, anti-infl ammatory and diuretic activities (Ozbek et al, 2009).…”

Medical plants and their various extracts have been occasionally used in the treatment of many diseases. Astragalus is one of those medical plants and it has several biological activities. In the present study, the hexane extracts of six Astragalus species, which are grown in the eastern Anatolia region of Turkey, were isolated, and their mutagenic and antimutagenic properties were investigated by using Salmonella typhimurium TA1535, TA1537 and Escherichia coli WP2uvrA tester strains at 0.05, 0.5 and 5 microg/plate concentrations. Known mutagens sodium azide (NaN(3)), 9-Aminoacridine (9-AA) and N-Methyl-N'-nitro-N-nitrosoguanidine (MNNG) were used to determine antimutagenic properties of hexane extracts. The results showed that all hexane extracts, investigated in the present study, can be considered genotoxically safe because they do not have mutagenic activity at the tested concentrations. But, a great many of them have antimutagenic activity against 9-Aminoacridine known as a model intercalator agent. The inhibition rates obtained from the antimutagenicity assays ranged from 27.51% (A. macrocephalus--0.05 microg/plate) to 54.39% (A. galegiformis--5 microg/plate). These activities are valuable toward an extension of the employ of these drugs as new phytotherapeutic or preservative ingredients.

Introduction In the Flora of Turkey, Fabaceae (Leguminosae) is one of the largest families in terms of species number, after Asteraceae (Vural et al., 2008). It includes annual or perennial plants, herbs, trees, and shrubs. Fabaceae is recognized by usually stipulate, bipinnate, simply pinnate, digitate, trifoliolate, or simple leaves; actinomorphic or zygomorphic, hypogynous or sometimes perigynous flowers; and legume or lomentum as fruits (Davis et al., 1970). The genus Astragalus L. (Fabaceae) is one of the largest genera of vascular plants, with 2500-3000 taxa and more than 250 sections (Karamian and Ranjbar 2005). The genus Astragalus belongs to the tribe Astragaleae of Papilionoideae in Fabaceae. It is distributed mainly in arid and semiarid mountainous regions of the northern hemisphere and South America. The genus is most diverse in southwest Asia (Akpulat and Çelik, 2007). Iran, with 750 species, is one of the centers of diversity of the genus (Ghahremani-nejad, 2005). The genus is divided into 64 sections and represented by 475 taxa including 202 endemic species in the Flora of Turkey, with the majority occurring in the Irano-Turanian region (Karaman Erkul et al., 2015). The new species belongs to the sect. Malacothrix Bunge and seems to be distinct among the Turkish species. According to Podlech and Zarre (2013), the sect. Malacothrix is represented by approximately 25 species in Turkey and, in this section, 12 species are endemic to Turkey. Astragalus sect. Malacothrix, represented by 90 species in Iran, is one of the largest sections within the genus (Podlech et al., 2010). Bunge (1868) placed the section together with seven other sections into the subgenus Hypoglottis Bunge. All members of the subgenus share similar morphological characters such as dense capitate or spike-like inflorescences (Ranjbar and Mahmoudian, 2012). This new species was collected from Bingöl Province, East Anatolia in Turkey between 2012 and 2014. The holotype specimen was deposited at Mustafa Kemal University in Hatay, Turkey, while isotypes were deposited at Bingöl University herbarium in Bingöl and ANK herbarium in Ankara. The specimens of the new species were cross-checked with material housed at various herbaria (ANK, GAZI). Consulted keys (Chamberlain and Matthews, 1969; Podlech, 1999; Podlech and Zarre, 2013) failed to identify this specimen. The studies showed that these specimens are representatives of a species new to science (Figures 1A and 1B). 2. Materials and methods The specimens reported here were collected from Bingöl Province (Turkey). The collected specimens were dried and flowers preserved in 70% ethanol for further studies. The flower and leaf measurements were performed on fresh and alcohol preserved materials. The pollen grains were measured under light microscopy and from nonacetolyzed samples, and prepared according to the Wodehouse method (Wodehouse, 1935). The long axis
