(Caryophyllaceae) led to the recognition of a new species Minuartia sabalanica based on the material from NW Iran. The new species is morphologically related to M. rimarum, an endemic only known from the central and southern Turkey, and M. umbellulifera known from Turkey and Iran. Diagnostic characters of the new species are discussed. In addition, a Latin diagnosis, description and illustration of the new species are given.

According to the latest study, seven sections were determined for the subgen. Minuartia. Identification key, distribution map and taxonomic description for each species were demonstra- ted. Within the species investigated, two new species i.e. M. sabalanica Assadi & Mostafavi (from NW Iran) and M. khorassanica Assadi & Mostafavi (from E Iran) were introduced for the first time to the world of science. In addition, the new combination, M. lineata Bornm. subsp. litwinowii (Schischk.) Assadi & Mostafavi, was introduced based on taxonomic rank reduction of Minuartia litwinowii Schischk. Moreover, taxonomic characters of an endemic species Minuartia urumiensis Bornm., was investigated according to the type specimen`s data. In this study, a general revision of all the introduced species from Iran in different floras (flora Iranica, flora de` Iran, etc.) was performed precisely and according to taxonomic studies the existence of some species recorded from Iran, i.e., M. thymifolia, M. tenuifolia, M. anatolica, M. setacea, M. dianthifolia, M. pungens, M. lydia, M. turcomanica, M. oreina, M. brevis, M. wiesneri and also M. viscosa, was controverted.

The species has a limited distribu-tion in E. Iran close to the Afghanistan frontier. Minuartia afghanica Rech. f. from Afghanistan and Pakistan is morphologically related to the new spe-cies but it is not known in Iran. The most important differences between the new species and M. af-ghanica are mainly in the shape of sepals and leaves and pedicel length. Moreover the two species have quite distinct ranges. Minuartia lineata BORNM. is another relative of the new species differing from it mainly in reproductive characters. The new species is illustrated and compared with M. lineata based on seed and pollen grain data. An identification key to distinguish these three species is given. In addition, Minuartia litwinowii Schischk. from Turkmenistan and adjacent areas in Iran is reduced to the rank of subspecies as M. lineata subsp. litwi-nowii. Identification key and selected specimens are given for the two subspecies ...

In the present study, materials of two subspecies of O. spinosa from different localities of Iran alongside some other native species of the genus were included in phylogenetic analyses. In addition, over 50 accessions were obtained from GenBank. In order to clarify the exact number of subspecies of O. spinosa in Iran, datasets were obtained from sequencing of nuclear ribosomal ITS (nr DNA ITS) and trnL-F plastid (cp DNA) regions and analysed. Three taxa belonging to O. spinosa L. complex (O. spinosa subsp. leiosperma, O. spinosa subsp. antiquorum, and O. arvensis=O. spinosa subsp. arvensis) were previously reported from Iran. Based on Maximum Parsimony and Bayesian analyses of the molecular datasets, it is shown that, unlike the previous reports, Iranian O. spinosa complex belongs to only two subspecies (i.e. leiosperma and arvensis subspp.). In addition, we also found that, O. spinosa subsp. antiquorum is not present in Ira...

The aim of the present study was to investigate the genetic diversity, population structure and morphological variations of 70 individuals belonging to seven geographical populations of Hamadan, Lorestan, Kurdistan and Chaharmahal and Bakhtiari provinces, employing inter-simple sequence repeat (ISSR) markers. In order to estimate morphological variations 38 characters were used. For molecular investigations, three gene pools in the country were identified using STRUCTURE analysis and K-Means clustering and also separation by the distance among the mentioned populations was defined properly. The Mantel test showed correlation between genetic and geographical distance. Analysis of molecular variance (AMOVA) demonstrated a significant genetic variability among the studied populations. It showed that 52% of total genetic variation was due to within-population diversity...

The aim of the present study was to assess essential oil content and variability in seven natural populations employing GC-FID and GC-MS analyses. Aerial parts of the specimens were collected at the full flowering stage. Overall, 27 chemical components were determined in the populations. The essential oil yields varied from 0.05% to 0.12%. The most abundant compounds were germacrene D (10.7-51.7%), β-sesquiphellandrene (0.8-54.6%), β-elemene (0.3-39.5%), juniper camphor (3.5-20.8%), limonene (0.4-19.6%) and α-pinene (0.4-4.5%) among the populations. Due to some variations observed in the essential oil components between populations, four different chemotypes were recognized including Chemotype I (germacrene D/β-sesquiphellandrene/juniper camphor), Chemotype II (β-elemene/germacrene D), Chemotype III (germacrene D/β-sesquiphellandrene) and Chemotype IV (β-elemene/germacrene D). The variations that occurred in chemical compositions among populations could be valuable in the pharmaceutical industries and conservation strategies.

In the present study, genetic variation of 70 individuals belonging to seven natural populations of four provinces was investigated using Random Amplified Polymorphic DNA (RAPD) markers. Ten out of twenty-two RAPD primers employed in this study, generated 110 highly amplified and reproducible loci and a mean of 11.1 bands per primer and 48.13% of polymorphism was obtained. According to our results, the primer OPA10 presented the highest effective number of alleles, Shannon's index, and genetic diversity. The highest value of genetic identity (0.916) was determined between Hamadan, Nahavand and Hamadan, Alvand Mts. populations and the highest genetic distance (0.277) was observed between Hamadan, Asadabad and Kurdistan, Qorveh populations. Therefore, there is an obvious correlation between genetic diversity and geographical distribution. PCA was obtained based on RAPD molecular data and Neighbor Joining (NJ) dendrogram was provided successively. Similar results were attained employing UPGMA and Neighbor Joining dendrograms, supported by PCA ordination plot. Overall, almost moderate level of polymorphism was obtained by RAPD molecular markers at the population level that shows a reasonable amount of intraspecific variability. The reason might be due to the low level of gene flow between populations that could give rise to high genetic differentiation.

For this purpose, mature pollen grains taken from unopened flowers, were prepared, fixed and exhaustively investigated using Scanning Electron Microscopy (SEM). In order to perform the pollen micro-morphology of Minuartia, and to find its significance in taxonomy of the group, qualitative and quantitative variables related to the shape, size, ornamentations and pores were studied. Cluster and PCA analyses of qualitative and quantitative data were performed to demonstrate the pollen grain similarities among the species. According to our results, Minuartia species exhibit either sub-spherical or polyhedral pollen shapes. Pollen size also varies among different species. The longest polar axis length (P) belongs to Minuartia meyeri Bornm. (34.3±0.26µm) and the smallest one to M. montana L. (15.8±0.26µm). Pore ornamentations differ from prominent granular to slightly or distinctly sunken granular. The number of pores also varies considerably depending on species. It ranges from 10 (in M. meyeri and M. acuminata Turrill) to 24 (in M. subtilis Hand.-Mazz.) on two pollen hemispheres. The most reliable characters in this study were pore diameter (annulus included) (D), equatorial diameter (E), polar axis length (P), the distance between two pores (d), pollen outline, Pore diameter (annulus excluded) (R), annulus diameter (a), P/E ratio, Puncta diameter and Echini diameter respectively. Echini vs puncta (Ec:Pu) diameter ratio appeared to be crucial for the distinction of some closely related species such as M. sublineata Rech.f. and M. lineata (Boiss.) Bornm., as well as M. montana and M. sclerantha (Fisch & C. A. Mey.) Thell. Moreover, three out of the 20 species have D: d ratio (pore diameter: the distance between two pores ratio) only ≥ 1µm. According to our results, some differences in quantitative and qualitative palynological characters of similar species were observed that could be useful. Despite the diagnostic value of palynological data at the species rank, it was not useful to circumscribe any taxonomic group at the higher ranks.

Its range of distribution extends throughout North, North – West and some parts of Iran Center. Biosystematic studies were used to identify the relationships between the species in this section and with representative species of another sections of Trifolium genus. A cluster analysis of morphology, pollen and seed characterestics divided the examined species into some groups. A factor analysis determined the sources of changes between species. Based on these observations, pollen features are not capable for seperating the species lonely, but it excessively confirms with the results of morphological traits. Seed micromorphological studies showed the effeciency of these characters to separate the similar species. According to karyological studies, the basic chromosome number in all examined species was x=8. Most of these species were polyploid and had different karyotype. So th...
