Species identification and population structure analysis in Geranium subg. Geranium (Geraniaceae)

摘要

Species identification is fundamentally important within the fields of biology, biogeography, ecology and conservation. The genus Geranium L. (Geraniaceae) comprises about 430 species distributed throughout most parts of the world. According to the most recent treatments, subg. Geranium is the largest subgenus with over 370 species classified in ten sections. The subg. Geranium is represented in Iran by 13 species. These species are grouped 3 sections. In spite vast distribution of many Geranium species that grow in Iran, there are not any available report on their genetic diversity, mode of divergence and patterns of dispersal.
