Zanjan province in NW Iran, with diverse climatic and topographic conditions includes a considerable part of Astragalus gene pool. From 2007 through 2009, a collection as complete as possible was made in this area by the authors. As a results of this study, we added 41 species to the already 75 known species for this province. Furthermore, 9 new species were described for the area from which one new species (Astragalus fausicola Podlech ex Bagheri, Maassoumi & F. Ghahrem. from sect. Incani DC.) is introduced.
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.
Astragalus sect. Astragalus (Fabaceae) in Iran
Botanical Journal of the Linnean Society, 2005
Astragalus rahiminejadii , a new species endemic to Iran, is described and illustrated. This species, which belongs to section Astragalus , is confined to the western part of Iran (Prov. Kermanshah) and is known only from a single population. Seed testa morphology as viewed under the scanning electron microscope is discussed and photomicrographs are provided. In addition, the geographical distribution and ecology of the species belonging to this section are discussed.
The distribution patterns of Astragalus sect. Hypoglottidei DC. (Fabaceae) in Iran
Nova Biologica Reperta
The distribution patterns of taxa belonging to the section Hypoglottidei DC. were investigated using DIVA-GIS software. Based on Zohary classification, five global patterns, with the exception of widely distributed species, include 1. Centro-Asiatic province, 2. Irano-Anatolian province, 3. Pontic province, 4. East Mediterranean subregion and 5. West Mediterranean subregion, were identified. In addition, the Iranian species of this section were classified in three patterns: 1. Central Zagros 2. Khorasan-Kopet Dagh 3. Central and Eastern Alborz. The maps and distribution patterns of the species were also presented.

Contributions to Genus Astragalus L. (Fabaceae) in Turkey
Commagene Journal of Biology
In this study, new arrangements are given for three Astragalus species that are endemic in Turkey. Astragalus physodes subsp. acikirensis (sect. Cystium) was raised to the species level; Astragalus darendensis was reduced to synonym of Astragalus scabrifolius (sect. Incani) and Astragalus tuna-ekimii was reduced to synonym of Astragalus chamaephaca (sect. Macrosemium). Comments are provided on the relevant taxa about their taxonomic positions by examining the recollected samples and the type samples.
The first record of Astragalus sect. Aegacantha (Fabaceae) in Iran
Nordic Journal of Botany, 2003
A new distinct population of Astragalus leiosemius. hitherto unknown to science, is reported for the first time from the eastern Alborz mountains in the Irano-Turanian part of Iran, at an altitude of 2400 m, far disjunct (ca. 800 km) from the populations at the Asia media and Afghanistan. The new taxon is described and illustrated as Astragalus leiosemius subsp. sabzevarensis. This orophilous and tragachantic plant belongs to A. sect. Aegacantha. On the basis of some important data on morphology, ecology and chorology, the new taxon is reported and its affinities and differences with regard to close taxa are presented. A. sect Aegacantha is recorded for the first time from the eastern part Iran.
