This study concerns the cytotaxonomic investigations on twelve species belonging to three sections from the genus Vicia in Iran. A taxonomic background of the genus is given in brief. The previous counts reported for the genus in Index to plant chromosome number are summarized. In addition to one new count, the chromosome numbers of four species are reported for the first time. Briefly, the ...

the genus astragalus l. (fabaceae) is reviewed from both phyloenetic and taxonomic points of view. as the largest genus of flowering plants it has attracted many researchers, but much work remains to be done. a short taxonomic history with special focus on infrageneric classification of the genus, a list of phylogenetic studies including the applied markers and sampling strategies as well a...

new evidence gained by the study of foraminifera from khuzestan province in southwest iran reveals that the basal limit of the genus heterostegina is not restricted to the eocene epoch. by introducing a new species of this genus (h. rezvaninejadi), this study shows that the early appearance of this genus should be lowered down further still, at least, into the middle paleocene.

Due to the importance of the Arasbaran forest (E. Azarbaijan, N.W. Iran) as a biosphere preserve and having a rich flora and fauna, macrofungi flora of Arasbaran region, were studied from 2003. This is the first in a series of publications on floristic studies of macrofungi of Arasbaran forests. In this paper, species of the genus Cortinarius, subgenus Myxacium are studied.The genus Cortinarius...

Euphorbia is a genus of flowering plants belonging to the family Euphorbiaceae. Consisting of 2008 species. The genus Euphorbia produces an irritant, which constitute a health hazard to humans and livestock. The genus Euphorbia is one of the largest and most complex genera of flowering plants, however, several botanists have made unsuccessful attempts to subdivide it to smaller genera.  Many Eu...

The genus Cyperus belongs to tribe Cypereae, subfamily Cyperoideae and family Cyperaceae that is the largest genus in this family after Carex. The classification of genus Cyperus is still unsettled because of morphological variations and therefore, makes determination of subgenera boundaries and species difficult. In Flora Iranica (KUKKONEN 1998) this genus was divided to six subgenera. In this...
