In this study, phylogenetic relationships and evolutionary trends of morphological characters of Astragalus sects. Acanthophace and Aegacantha were studied using nrDNA ITS and rpl32-trnLUAG datasets while Astragalus stocksii was selected as the outgroup. The phylogenetic results indicated the non-monophyly of A. sect. Acanthophace in its current circumscription due to the distant exclusion of A. ovigerus from the core group, and incongruence between nuclear and plastid datasets on the basis of different position of latter species in the resulted phylogenetic trees. Astragalus sect. Aegacantha was also found to not being monophyletic due to the distant position of A. montis-parrowii from the other representatives of the section while accompanying with other spiny Astragalus species. The Optimization of 32 morphological characters on the Bayesian combined tree indicated that some characters were most useful for delimitation of taxa in sections Acanthophace and Aegacantha. The results ...

Introduction The sect. Hymenostegis Bunge seems to be a disagreement section with its number of species in the genus Astragalus. The first revision of this section with 26 species established by Bunge (1868). Later on, present author during the local revision for Astragalus in Iran increased the number of species to 35 distinct taxa (Maassoumi 1995). This critical work was not also confidence for specialists, in this reason the section was revised again (Zarre & Podlech 1996), unfortunately, these authors without studying of the type of recent species, unreasonably reduced the number of taxa. Finally for preparing Flora Iranica treatment (Podlech & Maassoumi 2001) revised the section again with new collections. In this work with describing more new taxa, the number of species increased to about 40 distinct species. Recently three more new species were described (Podlech 2003; Ghahremani nejad 2004). Finally, another new species is described by the author. So, with this short histori...

The Iranian materials of the genus Vicia were reviewed. A critical study of 500 specimens collected for this study and additional herbarium specimens led to reporting a new subspecies, V. villosa Roth. subsp. dasycarpa (Ten.) Cav. from Iran. In addition, recollection and identification of two species, V. mollis and V. lathyroides which were not deposited in any of the Iranian herbaria before. According to the results of this study 15 sections within the Iranian materials of Vicia were recognized. Also the following changes were applied: revival of two sections Crocea and Lenticula; transferring the members of sect. Cassubicae to sect. Vicilla; V. koeieana from sect. Anatropostyla to sect. Ervilia; V. hirsuta from sect. Ervum to sect. Ervilia; V. crocea from sect. Vicilla to sect. Crocea; recognition of the subgen. Cracca. Four new synonymes made: subgen. Vicilla as synonym of subgen.

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.

Four new species of the genus Astragalus L. sect. Hymenostegis Bunge are described from NW Iran, prov. Zanjan: A. austromahneshanensis, A. qeydarnabiensis, A. subkohrudicus, and A. subrecognitus. They are compared with their closest relatives. Furthermore, A. sosnowskyi Grossh. is recorded for the first time from Iran and A. velenovskyi Náb0lek is excluded from the list of Iranian species of Astragalus. Based on these new findings, the number of species attributed to sect. Hymenostegis reaches to 57, with an endemism rate of about 75 % in Iran. So, Iran, especially the NW of the country, is the main diversity center of this section.

The vast majority of highly valuable species of the Leguminosae in temperate latitudes belong to the Inverted Repeat-Lacking Clade (IRLC). Despite having a generally conserved monosymmetric floral morphology, members of this group are remarkable with a pronounced diversity of floral sizes, modes of staminal fusion, and pollination strategies. This paper examined androecia and floral nectaries (FNs) in selected genera of the IRLC. External morphology was investigated using stereomicroscopy and scanning electron microscopy. In some cases, the pattern of staminal fusion was additionally examined in transverse sections using light microscopy. Androecia of all selected genera fell into one of four types, viz., monadelphous, pseudomonadelphous, diadelphous or diadelphous reduced (with inner stamens converted into sterile staminodes). However, there was significant variation in the stamens’ mode of contact, as well as the shape and size of the fenestrae providing access to FNs. Some types ...

Micromorphological features regarding lower surface of leaf epidermis and seed surface in eight Crataegus taxa representing the series Pentagynae and series Crataegus subseries Erianthae were studied by scanning electron microscopy. All data were analyzed using Anova and PCA statistical methods. Qualitative traits of lower surface of leaf epidermis include relief of cuticle membrane, striations and kinds of crystalloid waxes allow distinct delimitation at infrageneric, interand infraspecific levels, whereas the quantitative characteristics are less informative. The seed traits compared to the leaf features provide less reliable characters in the taxonomy of the genus.

The taxa of Astragalus section Hymenostegis are an important element of mountainous and steppe habitats in Southwest Asia. A phylogenetic hypothesis of sect. Hymenostegis has been obtained from nuclear ribosomal DNA internal transcribed spacer (ITS) and plastid ycf1 sequences of up to 303 individuals from 106 species, including all 89 taxa currently assigned to sect. Hymenostegis, 14 species of other Astragalus sections, and two species of Oxytropis and one Biserrula designated as outgroups. Bayesian phylogenetic inference and parsimony analyses reveal that three species from two other closely related sections group within sect. Hymenostegis, making the section paraphyletic. DNA sequence diversity is generally very low among Hymenostegis taxa, which is consistent with recent diversification of the section. We estimate that diversification in sect. Hymenostegis occurred in the middle to late Pleistocene, with many species arising only during the last one million years, when environme...

As a result of a taxonomic and phylogenetic revision of Astragalus section Hymenostegis we identified a new species of Astragalus from northwestern Iran, namely A. remotispicatus spec. nov., which is described and illustrated here. It is morphologically similar to A. karl-heinzii in possessing a lax inflorescence. Phylogenetic inference of the nuclear ribosomal DNA internal transcribed spacer (ITS) region support A. remotispicatus as a clearly distinct species within the lax-inflorescence group of this section. Also the placement of A. sciureus var. subsessilis was found to be wrong and this taxon should be treated as a synonym within A. kohrudicus.

The genus Pulicaria Gaertn belongs to the tribe Inuleae (Asteraceae). This genus includes five species in Iran (P. dysenterica, P. vulgaris, P. Arabica, P. gnaphalodes and P. salvifolia). The most diagnostic morphological characteristics were kind of pappus, achene, corolla, phyllaries and form of leafs. In the recent study by Anderberg, focusing on the close relationship between the genus Pulicaria and platychaete, they have been announced synonymous. Platychaete includes five species in Iran (P. glucescens, P. carnosa, P. velutina, P. mucronifolia and P. aucheri). In this study the relationships between them were confirmed and therefore, the Anderberg’s view of convergence of the two genera was attested. Also, species identification key, phenogram and distribution map in Iran were provided and discussed.

Foliar anatomy of nine species of genus Salix belonging to different subgenera including Salix aegyptiaca, S. caprea, S. cinerea, S. elbursensis, S. euxina, S. issatissensis, S. triandra, S. wilhelmsiana, and S. zygostemon (S.cinerea x S. elbursensis) were studied using light microscope. Several features of leaf anatomy, i. e. transverse section outline, lamina thickness, epidermis characteristics, hypodermis existence, mesophyll features, crystal types, vascular bundles characteristics, etc. are discussed here. Several anatomical characters in this study confirm the infrageneric classification of Salix. On the base of presence or absence of hypodermis layer in lamina, the genus Salix can be divided into two types. The outline of the transverse sections and stomata type differ among sect. Cinerella and the other sections. The delimitation of the closely related species of S. aegyptiaca, S. caprea and S. cinerea belong to sect. Cinerella is difficult, but they can be distinguished ba...

ABSTRACT Most papilionoid legumes (Leguminosae) are characterized by zygomorphic flowers. Features of monosymmetry are inherent to all floral whorls. We compare flowers of two species of papilionoid legumes with anomalously radialized corollas. Except for vexilloid mode of all five petals, these flowers were remarkable with their free androecium and (in case of Clitoria ternatea) actinomorphic calyx. The symmetry of the gynoecium remains unaltered. These correlations point at a strong interrelation between perianth and androecium symmetry control, possibly governed by the same genes. A review on floral symmetry in related papilionoid genera indicates that staminal fusion is only possible in case of a discernible adaxial petal (flag). This rule has some exceptions which contribute to the idea of independent recurrent origin of monosymmetry in different leguminous clades.
