Abstract
Kura bleak, Alburnus filippii, a member of the family Cyprinidae, is found in the rivers of Aras and Sefidrud, and the Anzali lagoon of Iran. The current study was conducted to provide a detailed osteological description of this sp-ecies since there was not adequate information in this regard. In order to attain this goal, 20 specimens were collected from the Ahar Chay River by electrofishing device, and fixed in 10% buffered formalin. The specimens were cleared, stained with alizarin red S and alcian blue for osteological examination and a detailed description of its skeletal structure was provided. The results showed that this species can be distinguished from other members of this genus in Iran by a combination of osteological characters, including having pointed process of the maxillae, dorsal tilting of the coronoid process, protruding of the anterior margin of the hyomandibular, fan-shaped anterior part of the basihyal, pointed end of the pre-vomer posteriorly, small fourth infraorbital and 11 pterygiophors in the dorsal fin.

Abstract
Distribution of rivers, pools and grasslands, being large or small and perennial or temporary, have created conditions suitable for the establishment of wetlands, especially in the highland regions of the Country. These habitats are highly important for the preservation of biodiversity and other ecological aspects. The present study aimed to identify wetlands in the Kermanshah Province, Iran, and map their distribution. The investigation was carried out on the basis of the conventional taxonomic studies of the region by doing field observation in 31 aqueous habitats in Kermanshah Province. The flora of each habitats and the life form and geographical distribution of the species were investigated. In total, 617 plant specimens, belonging to 288 species, 218 genera and 62 families, were collected identified and stored in the herbarium of the research center of agriculture and natural resources of Kermanshah Province (RANK). Asteraceae with 41 species, Poaceae with 31 species, Fabaceae with 31 species and Brassicaceae with 24 species were found to be the most important families of the wetlands studied. Trifolium with 11 species and Bromus with 6 species were the most important genera, in terms of species richness. Detection of the biological forms showed that 40.3% of the species were trophytes, 35/5% were hemicryptophyts, 6/1% were phanerophytes, 14/23% were cryptophytes and 3/72% were chamaephytes. The chorology of species showed that 93 species belonged to more than two elements (32%), 92 species (31%) to the Irano-Touranin elements, 32 species to Irano-Touranin- Mediterranean (11%), 9 species to Irano-Touranin- Euro-Siberian with (3%) and 23 species were found to be cosmopolitan elements (8%).

Abstract
Solanum chenopodioides is introduced here as a new record for the flora of Iran from the coastal areas of the Caspian Sea, Guilan province. This species grows in Bujagh National Land-Sea Park, on sand dunes, along with other coastal psammophytic plants. This species belongs to the Morelloid clade. It differs from the related species S. nigrum, by its shrubby nature, perfect leaves margin, dull berries, bi-colored petals in the middle, and peduncle that bends a bit downwards in fruit. This plant is native to southern South America. It is introduced as a common weed all over the world; in addition, this species is considered an alien species for the flora of Iran. Transit of goods, especially wool, to the different parts of the world is one of the ways of the spread of this species all over the world. In addition to providing some pictures of the plant, some notes about the distribution and ecology of this species were also provided in this paper. The numerous reports of alien species from Bujagh National Park in recent years could be regarded as a credible warning for the stability of native vegetation of the area and existing ecosystems.
