Based on morphological and molecular evidence, two new species of Silene are recognized described here, S. penduliflora F.Jafari, Keshavarzi & Doostm. sp. nov. thyrsiantha Mirtadz. The newly discovered distributed in the central southeastern parts Iran, growing rocky habitats. Relationships among these their close relatives demonstrated using nrDNA ITS cpDNA rps16 phylogenies. ghahremaninej...

Background and aims – Species delimitation is a necessary investigation for widely distributed species. Examination of herbarium specimens descriptions in local floras revealed that two forms Silene villosa were recognized. Form B S. has been identified as separate species named wendelboi . However, the latter was not treated floras. By using molecular tools, we investigated if these should be ...

Coalescent-based inference of phylogenetic relationships among species takes into account gene tree incongruence due to incomplete lineage sorting, but for such methods to make sense species have to be correctly delimited. Because alternative assignments of individuals to species result in different parametric models, model selection methods can be applied to optimise model of species classific...
