A new species of Astragalus (Fabaceae) from Turkey

TURKISH JOURNAL OF BOTANY, 2013

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.

Astragalus unalii (Fabaceae), a new species from Turkey

TURKISH JOURNAL OF BOTANY, 2016

The genus Astragalus L. (Fabaceae) has two phylogenetic branches; one of them is Old World (Asia, Europe, and Africa) and the other one is New World (America). It has about 2000 taxa with 136 sections in the Old World (Podlech and Zarre, 2013). It is represented by 478 taxa in 63 sections and 202 (42%) taxa endemic to Turkey (Aytaç et al., 2012). Three new endemic taxa were added to the Turkish flora in 2012 and 2013 (Taeb and Uzunhisarcıklı, 2012; Dinç et al., 2013; Karaman and Aytaç, 2013) and the number reached 486. The sect. Malacothrix Bunge is represented by 119 taxa in the Old World and 25 in Turkey, of which 12 are endemic (Podlech and Zarre, 2013). According to Taeb and Uzunhisarcıklı (2012), the sect. Malacothrix is represented by 17 taxa and 10 of them are endemic to Turkey. The sect. Malacothrix is common in the Irano-Turanian phytogeographic region and has a systematic problem. According to Chamberlain and Matthews (1970), the sect. Malacothrix is caulescent, otherwise subacaulescent to acaulescent (Podlech and Zarre 2013). It is difficult to describe and decide if it is caulescent or not from herbaria specimens. Interesting specimens of Astragalus were collected from Karadağ (Karaman Province) during the field trips by Ö. Çeçen, H. Mısırdalı, and Ünal in 2013. After closer examination and consultation with the treatment in the Flora of Turkey (Chamberlain and Matthews, 1970) and a taxonomic revision of the genus Astragalus in the Old World (Podlech and Zarre, 2013), it was realized that the specimens are different from the other known Astragalus species. This new species was also cross-checked with those kept in GAZI, ANK, and HUB. 2. Materials and methods The morphological data used in the description of the new species were directly obtained from specimens collected by the authors from Karaman Province and by using a binocular stereoscopic microscope when necessary. The pollen and seed morphology of the new species were examined with scanning electron microscopy (SEM) at GAZI. The pollen was treated with 70% alcohol and then dried before mounting on stubs with gold for the SEM study. The SEM photomicrographs were taken with the JEOL JSM 6060 SEM at Gazi University. The pollen terminology of Punt et al. (1994) was used in the description. Plant names were checked using IPNI (2015). The type specimens of new species are deposited at GAZI, ANK, HUB, KYN, and YILDIRIMLI.
