Index of New Taxa

Erodium (Geranaiceae) species are distributed in different habitats of Iran. Some species are of medicinal importance while some are well known weeds. There are no chromosome counts for Erdoium species of Iran. Chromosome numbers are given for six taxa of Erodium (Geraniaceae) from Iran: E. cicutarium (2n=36), E. ciconium(2n=18), E. malacoides (2n=20), E. moschatum (2n=20), E. neuradifolium (2n...

The Caspian (Hyrcanian) lowland forest zone in northern Iran is characterized by small remnant alder forest communities, dominated or subdominated with an Euxino-Hyrcanian element, Alnus glutinosa ssp. barbata. The first floristic inventory of these alder forests in northern Iran is presented. The floristic catalogue is based on the data of 133 phytosociological releves in eight different alder...

In this study, a taxonomic status of the genus Roemeria in Iran is reviewed. The study of morphological characters of collected and herbarium specimens led to the introducing of two new taxa, namely, R. hybrida subsp. maculata and R. refracta var. alba. In addition, five synonymies are made as following: R. refracta var. albomarginata and R. refracta subsp. occidentalis as synonymies of R. refr...

The meiotic chromosomes of 10 species (Pohlia elongata, Anomobryum cymbifolium, Brachymenium acuminatum, B. ochianum, B. sikkimense, Bryum cellulare, B. pseudotriquetrum, B. apiculatum, B. capillare and B. atrovirense), in four genera of the family Bryaceae of acrocarpous mosses are studied with special emphasis on their evolution, polyploidy and cytological features with reference to interrela...

Fungi associated with leaf spot symptoms of plants in forest areas of Golestan province, Iran, were collected and examined based on morphological characteristics of conidiophores, conidia and conidiogenous loci. Ten taxa were identified. Among the taxa, Passalora cf. bacilligera and Pseudocladosporium hachijoens are new records for the mycobiota of Iran. Cercospora on Eruca sp. was morphologica...

Assessing priorities is the most important action in conservation programs. Rudimentary, mapping of diversity, and distribution patterns have been used to set priorities on diverse scales. The distribution patterns of plant taxa, largely reflect an actual ecological niche. Convolvulaceae s.str exhibits cosmopolitan dispersal of diverse life forms and includes 50–60 genera comprising 1600–1700 s...

the osteology of the hyoid and branchial arches in several representatives of eurypterygian fishes were examined. the hyoid arches consist of a single basihyal and urohyal, and the arch on each side consists of a dorsal and a ventral hypohyal, an anterior and posterior ceratohyal, an interhyal, and branchiostegal rays that are borne on the ceratohyals. the branchial arches consist of three sing...
