Nectary morphology of Matthiola species (Brassicaceae) in the Flora Iranica area was examined using a stereomicroscope to evaluate its systematic significance and assess infrageneric relationships. The study demonstrated that, most characters of the nectaries were constant among different...

The Mirabad protected area (S. Azarbaijan, Iran) has a variety of ecological nurseries due to elevation of the sea, physiographic factors, micro-climates and soil types, and has high vegetation diversity. Mirabad protected area in the Piranshahr-Sardasht axis is between the latitudes of 36° 23′ and ...

During an exploration in boundary areas of Salmas (W Azarbayjan province, Iran) in 2016, an interesting plant from the genus Silene was collected. Determination of the plant material by using Flora Iranica was showed that, it is an unknown plant, but the specimen was determined as Silene armena...

Caryophyllaceae is the fifth largest Iranian plant family in terms of number of species where most of its species are Irano-Turanian. About 30% of these species are endemic of Iran. There are continuously uncertainties regarding the circumscription of genera, and especially because of new molecular ...

The phylogenetic relationships of the genera Fragaria and Duchesnea, and their closely related species are reconstructed using 17 morphological characters. Data matrix consisted of 11 taxa belonging to two species of Fragaria, two species of Duchesnea, two species of Potentilla, and also five...

The presence of organic compounds and high amount of secondary metabolites (polysaccharides, phenolic component, etc.) in mosses cause difficulties in DNA extraction that are followed by problems in PCR reactions. In lower plants, various methods have been used for DNA extraction including silica...

Noticeable variation was observed in a number of morphological characters in the Glycyrrhiza specimens in various habitats in north of Iran. To study these variations, two taxa related to the Hyrcanian region from all four known taxa of this genus in Iran, including Glycyrrhiza echinata, and G....

Cyanobacteria represent a small taxonomic group of photosynthetic prokaryotes which some of them are capable of N2 fixation and also possess a tremendous potential for producing a wide range of secondary metabolites. It has been suggested that, some of these microorganisms, especially heterocystous ...

In the current survey, a detailed account in pollen morphology of 22 species of Sedum s.l. in Iran are presented using light (LM) and scanning electron microscopy (SEM). The pollen grains are radially symmetrical, isopolar, mostly trizonocolporate and rarely tetrazonocolporate, small-to-medium...

This study was done to compare the plant morphology of Ambrosia psilostachya DC. (ragweed) in four habitats of roadsides (1), paddy field margins (2), around residential areas (3) and coastal areas (4) in Bandar-e Anzali (Guilan province, north of Iran) in 2019. Sampling was random in five growth...
