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.
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 sect. Dissitiflori (Fabaceae) in Iran
Nordic Journal of Botany, 2004
Two new species, Astragalus ghahremaninejadii and A. kharvanensis are described from Iran and illustrated. They belong to A. sect. Dissitiflori, which contains species with bifurcate hairs. The first is similar to A. pendulinus, A. baldschuanicus, A. kustanaicus and properly A. marguzaricus and only known from a single collection close to the Turkmenistan frontier. The second shows morphological similarities with A. dendroproselius especially A. viridis. Also A. dendroproselius is reported as a new record for the flora of Iran.
Two new species and a new record of the genus Astragalus (Fabaceae) from NE Iran
Nova Biologica Reperta, 2018
During the study on the specimens of Astragalus sect. Ammodendron in the herbarium of Ferdowsi University of Mashhad (FUMH), based on the last and most recent sources, two new species, i.e. A. microfoliolatus sp. nova and A. rashed-mohasseli sp. nova were found and described. Morphological evidence confirmed that the belonging of these taxa to Astragalus sect. Ammodendron. The most important differences between A. microfoliolatus and its closest relatives are leaflets with very small size and glabrescent legume. Also, the main distinctive characters ofA. rashed-mohasseli are the presence of hairs on the dorsal side of vexillum, oblong legume and short rachis. Hairy vexillum has been obseverd for the first time in this section. In addition, A. aiwadzhi is recorded as a new species for the flora of Iran. Taxonomic descriptions, illustrations and distribution maps are provided to expedite identification.
Astragalus ghouchanensis (Fabaceae), a new species from Iran

Astragalus ghouchanensis Souzani, Zarre & Maassoumi (Fabaceae) is described and illustrated as a new species from Iran. It is compared with some similar species in Astragalus sect. Dissitiflori. Some notes are given on the affinities of sect. Dissitiflori and sect. Erioceras.
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.
Rediscovery of Astragalus saganlugensis (Fabaceae, Galegeae) in Iran after 184 years
Phytotaxa, 2018
Astragalus Linnaeus (1753: 755) (Fabaceae), with about 240 sections and 3000 species, is the largest genus of flowering plants (Podlech & Zarre 2013). Sect. Hypoglottidei De Candolle (1825: 281) with 46 species is one of the taxonomically most problematic sections. The majority of these species grow in Turkey and Iran (Chamberlain & Matthews 1970; Podlech et al. 2010; Podlech & Zarre 2013). Astragalus saganlugensis Trautvetter (1858: 323) is common in both countries, but also in Armenia and Azerbaijan. Trautvetter (1858) described this species as a member of section Hypoglottidei, but did not designate type material for the species. Podlech and Sytin (1996) were the first to choose a lectotype for this species.
Astragalus hakkianus a new species of Astragalus (Fabaceae) from N.W. Iran
Feddes Repertorium, 2013
Astragalus kazempourii is described as a new species from Firuzkuh in Tehran province, Iran. Morphological data and phylogenetic analyses of the nrDNA internal (ITS) and external transcribed spacer (ETS) regions places this species within sect. Hypoglottidei as sister of Astragalus parvarensis. The new species differs morphologically from A. parvarensis by having a short stem densely covered with basifixed hairs, short peduncles and a long calyx. A distribution map of the new species is provided and the habitat condition of the taxon and close relatives, as well as the conservation status of A. kazempourii are discussed. The phylogenetic analyses conducted also support the recent transfer of Astragalus bojnurdensis from A. sect. Brachylobium to sect. Hypoglottidei, which was in accordance with the morphological characters of this species.
