Scutellaria is one of the largest genera in Lamiaceae with an estimated 400–500 species a nearly worldwide distribution. Most occur N hemisphere, Caucasus and wider Irano-Turanian region housing large number taxa, many them considered endemic. We present overall phylogeny monophyletic genus based on rapidly evolving plastid regions (matK-trnK, rpl16, trnL-F). Three well-supported clades are evi...

Artemisia sieberi Besser occurs in many parts of the Irano-Turanian floristic region, which is mostly distributed throughout Iranian plateau, especially Iran. This study aimed to identify effect soil and topography variables on A. distribution. We used canopy cover data fit models using generalized additive (GAMs). The results showed that response pattern along with gradient clay, saturation mo...

A global revision of Convolvulus L. is presented, Calystegia R.Br. being excluded on pragmatic grounds. One hundred and ninety species are recognised with the greatest diversity in the Irano-Turanian region. All recognised species are described and the majority are illustrated. Distribution details, keys to species identification and taxonomic notes are provided. Four new species, Convolvulusau...

Floristic studies are fundamental for the applied sciences such as rangelandmanagement and conservation. Unique ecological and climatic conditions in the NorthernKhorasan Province (NKP) make it a remarkable habitat for the floristic studies. Plant specieswere collected from 50 field sites, representing major habitats of winter and rural rangelands.Surveys were conducted during active growth per...

There are about 484 species of Hypericum in the Guttiferae family, which includes Hypericoideae. In Iran, this genus mainly found north, northwest, and center country, they key contributors to floral elements Hyrcanian mountains, Irano-Turanian, Mediterranean regions (such as Zagros). Medicinal, commercial, horticultural values associated with these plants.The genetic diversity was assessed thr...
