Twenty four species belonging mainly to Astragalus L. section Dissitiflori DC. and some related sections were analyzed using maximum parsimony and Bayesian methods on the basis of nrDNA ITS sequences and morphological data. Trees resulted from two datasets were in agreement on their overall topologies. Based on our results, members of the section Dissitiflori didn't constitute a monophyletic group. However, the section with inclusion of the species from the other related ones, considered to be a monophyletic group. Since A. virgatus as the lectotype of the section Dissitiflori was not included in the present study; it is difficult to evaluate the monophyly of the section and to delimit it explicitly. Astragalus juladakensis, shows a basal position in both nrDNA ITS and the combined nrDNA ITS-morphology trees, as a sister to the remaining species of the sect. Dissitiflori. However, according to the present study, the affinity of this species to the section appeared to be questionable. Based on our molecular data, three species belonging to the section Corethrum in Iran, are pertained to the sect. Dissitiflori. In addition, our results revealed that A. pravitzii, which had been transferred to sect. Ornithopodium Bunge, belongs to the section Dissitiflori.

A REVIEW OF THE GENUS ALNUS GAERTN. IN IRAN, NEW RECORDS AND NEW SPECIES
Habib
Zare
Tayebe
Amini
The genus Alnus Gaertn., with approximately 20 species, is of great economic importance and some of the species are as the source of timber in the north hemisphere. In the Hyrcanian forests, the trees of this genus have many critical roles especially in forest rehabilitation. Like most of woody plants in Hyrcanian forests, there are many taxonomic problems concerning the recognition of the species of the genus Alnus in Iran. To cope with, during the long term study on the trees of this genus in the most parts of Hyrcanian forests, many specimens of these trees in the field and in different sites were collected. The studies were performed on living and herbarium specimens and some of the most important local herbarium materials were studied too. According to the previous studies, the genus Alnus in Iran includes two species: Alnus glutinosa Gaertn. subsp. barbata (C. A. Mey) Yaltrik and Alnus subcordata (C. A. Mey.) Yaltrik with two varieties which are distributed in Hyrcanian forests. The results obtained from many specimens of Alnus revealed that there are three extra species and records including: Alnus djavanshirii Zare, Alnus dolichocarpa Zare, Amini & Assadi and Alnus orientalis Decne. as well as two subspecies viz. Alnus glutinosa Gaerth subsp. glutinosa and Alnus glutinosa Gaerth subsp. antitaurica Yaltrik. In this paper, botanical characteristics and ecology of the taxa are elaborated.

We reviewed the taxonomic status of the Iranian material of Trifolium sect. Fragifera (Vesicaria). A critical study of 156 accessions collected specifically for this study and additional 160 herbarium specimens led to the discovery of one new variety, T. tumens Steven ex M. Bieb.var. caespitosum Haerinasab and reporting two new records, T. tomentosum L. var. chthonocephalum Bornm. and T. clusii Godr. & Gren. var. gossypinumZohary. In addition, six synonymies are made: T. fragiferum L. var. pulchellum Lange as a synonym of T. fragiferum, T. tumens var. talyschense (Khalilov) Zoh. as a synonym of T. tumens var. tumens, T. physodes Stev. ex M. B. var. psilocalyx Boiss. as a synonym of T. physodes, T. resupinatum L. var. microcephalum Zoh. as a synonym of T. resupinatum var. resupinatum, T. bullatum Boiss. & Hausskn. ex Boiss. var. macrosphaerum Zoh. as a synonym of T. bullatum and T. tomentosum L. var. curvisepalum (Täckh.) Thieb. as a synonym of T. tomentosum var. tomentosum. Furthermore, we made some nomenclatural corrections for the Iranian material of the genus Trifolium sect. Fragifera. A taxonomic key to the Trifolium taxa sect. Fragifera was constructed and presented here.

In this study, 30 specimens (6 populations) from long-winged species of Onobrychis sect. Onobrychis including O. verae Širj., O. gontscharovii Vassilcz., O. ptychophylla Širj. & Rech. f., O. sosnovskyi Grossh. and O. araxina Schischkin were collected from their natural habitats in Iran. The specimens were biometrically assessed using 45 quantitative and 15 qualitative morphological characters. In order to study the genetic variations of different species, nucleotide sequence data from the internal transcribed spacer of the nuclear rRNA genes (ITS) were obtained. Data regarding longitude, latitude, altitude, slope inclination, slope direction, substrate, min/max annual temperatures, number of rainy days, annual precipitation as well as soil traits including texture, electrical conductivity, organic carbon, total nitrogen, available phosphorus and potassium, total neutralizing value, pH, and saturation percentage were recorded in each sample site. Cluster analysis of morphological characters showed two major groups separating northwest species from northeast ones. Furthermore, the ITS data analysis results showing two main groups, which are exactly in concordance with morphological groups. Also canonical correspondence analysis (CCA) of ecological data showed the precipitation, rainy days, sand% and silt% as the most effective factors for this separation. Furthermore it showed the effect of ecological factors on each species. Onobrychis araxina Schischkin is recorded for the first time from Azerbaijan Gharbi province, Iran. An identification key to the long-winged species of section Onobrychis in Iranis presented.

Astragalus remotiflorus Boiss. from section Anthylloidei DC. has three subspecies, that are endemic to Iran. A. remotiflorus subsp. nigrohirsutus is an endemic species in Fars province and is found on the mountain of Kharman kuh, 1760–3122 m. In this study cytological and morphological study were performed for this subspecies and A. remotiflorus subsp. remotiflorus, Also, the morphological characteristics of A. remotiflorus subsp. melanogramma were examined. The results indicate that A. remotiflorus subsp. nigrohirsutus is a hexaploid (2n=6x =48) with the karyotype formula of 15m+9sm. Symmetrical karyotype of this subspecies is in the class 2A. Morphological characteristics indicate that this subspecies with a small amount of mixed black hairs ca. 1 – 2.5 mm long on the peduncle and calyx distinguishes it from the other two subspecies. Also, it differs from subsp. melanogramma in having longer peduncle and lax inflorescence. A. remotiflorus subsp. nigrohirsutus is raised to the rank of species as A. nigrohirsutus.

NOTES ON THE ONOBRYCHIS CRISTA-GALLI (L.) LAM. (FABACEAE) IN IRAN
Farangis
Ghanavati
A taxonomic status of the Onobrychis crista-galli was reviewed in Iran. Morphological characteristics, chromosome number and ploidy level were studied in 30 populations of this species collected from natural habitats. The results showed that the populations of O. crista-galli with 16 or 32 chromosomes are diploid or tetraploid respectively. Diploid populations had 3-seeded pods with a spinulose first row of spines, while tetraploid populations had 2-seeded pods with the first row of spines simple. Thus, O. crista- galli have 2 varieties in Iran namely crista-galliand trilophocarpa (Sirj.) Townsend, that var. trilophocarpa is recorded as a new report to the flora of Iran

Shikhbaba Babayev
Thymus (Thyme) is one of the most important medicinal plants which is highly variable within and between the species. This variation is in morphology, components of essential oil and number of chromosomes. So, in this study, two Thymus (Thyme) species including Th. trautvetteri Klokov & Desj-Shost and Th. fedtschenkoi Ronniger which are distributed in south of Azerbaijan country, were investigated. Examined species belong to the sect. Serpyllum and subsection Kotschyani. Some species of this section are taxonomically very difficult and show the widest chromosomal variation. In this research, the somatic chromosome numbers of examined species were counted at least in five mitotic cells. The basic chromosome number was x=15 with two ploidy levels. Th. trautvetteri with 2n=4x=60 and Th. fedtschenkoi with 2n=2x=30 were tetraploid and diploid respectively. Chromosome counts for these species are new reports.

Pollen morphology of the genus Rheum (Polygonaceae) from Iran was studied by light microscope (LM) and scanning electron microscope (SEM). Pollen grains are usually auxiliary symmetrical, isopolar and tricolpate in equatorial view, while circular in polar outline. Exine sculpturing is variable and are sparsely faveolate to perforate, less microechinate (Rh. turkestanicum), perforate-favusus, microechinate (Rh. ribes) and perforate to foveolatus, densly microechinate (Rh. persicum). On the basis of qualitative and quantitative characters identification keys for species were prepared.

Pollen grains in seven species of Salix are studied with light Microscope and Scanning Electron Microscope. The results of LM showed that pollen grains are tricolpate and the overall shape is spherical to subprolate. In polar view, most of pollen grains were 3-lobed with convex lobes. The size of pollen was very variable. The Exine was reticulate. The characters of muri such as shape and size of lumen were varied in different species. The lumen was isodiametric or heteromorphic and the patterns were orbicular, elliptic or polygonal with rounded angle. Based on former studies the pollen grains in this study were referable to the following types: Salix alba type 6, S. issatissensis type 1, S. acmophylla, S. zygostemon and S. cinerea type 2, S. elbursensis type 5, S. excelsa type 3 and 6. Our results showed that shape and size of pollen grins are similar but the exine sculpturing is different and can be used for distinguishing the species. In addition, the exine pattern in S. zygostemon which is a hybrid species showed that S. cinerea is the male parent of this hybrid and the female parent is S. elbursensis.

In the study of the genus Cylindrospermum Kützing ex Bornet & Flahault (Nostocaceae) in terrestrial habitats, 18 specimens belonging to eight species were identified. Specimens were collected from 11 paddy field soils located in seven provinces of Iran. Five taxa, including Cylindrospermum sphaericum B. N. Prasad, Cylindrospermum catenatum (Ralfs) Bornet & Flahault, Cylindrospermum marchicum Lemmermann, Cylindrospermum minutissimum Collinsand Cylindrospermum muscicola Kützing ex Bornet & Flahault are considered as new records to Iran. An identification key, description and pictures of these species are presented in this study.

Miankaleh international wetland and peninsula are one of the main UNESCO biosphere reserve in Iran and Middle East. Phytoplankton diversity of the Miankaleh wetland was investigated from October 2009 to September 2010. Apart from the work done by Ramezannejad Ghadi, this study is the second floristic study of algae in the Miankaleh wetland in north of Iran. Five main algal groups were recorded namely: Bacillariophyta, Cyanobacteria, Chlorophyta, Euglenophyta and Xantophyta. A total of 94 species and varieties belonging to 47 genera were identified. Among them green algae formed the most abundant group making up 43 species and varieties from 18 genera. This was followed by Diatoms, with 31 species from 15 genera, Cyanobacteria, with 18 species from 12 genera. Euglenophyta and Xantophyta with 1 species make up an insignificant part of taxa. All of these taxa are new records for Miankaleh wetland and Mazandaran province.

Artemisia sieberi Besser is the most common species in Iran. In this research, yield and chemical composition of the essential oil of A. sieberi are studied from 34 populations in Semi-arid, Arid and Hyper-arid climate conditions. Also, plant seeds were collected from nature and planted in homogeneity condition of farm. The essential oils of harvested plants (including natural and farms plants) were isolated. The components of oils were identified by GC and GC-MS. T-student test showed significant difference between average of oil yields in both natural and farm plants. Correlation between yields of essential oil in natural habitats with ecological factors showed that days of precipitation, nitrogen, carbon and phosphor of soil were the most effective parameters in quantity of yields. Among chemical components, camphene, 1, 8-cineole, trans-thujone, camphor, borneol didn’t have significant difference between natural and farm plants. The results showed that chemical components of essential oil in A. sieberi can be valuable for recognizing of the species as chemotaxonomic indices. Also PCA analysis revealed that camphor, cis-thujone and trans-thujone are principal chemical components for separating of A. sieberi climatic groups.
