The present study provides an analysis of the floristic composition, life form and chorology of the plant species of Baraki Barak district, located southeast Kabul in Logar province. All plant specimens were collected in summer 2020 and spring 2021. The plant specimens were dried, transferred to the herbarium of the University of Guilan, Rasht, Iran and identified using Identification keys. The results led to the identification of 120 species of angiosperms belonging to 97 genera and 31 families. Asteraceae (23 species), Brassicaceae and Fabaceae (10 species each) were the largest families in the region. The results showed that therophytes with 54 species (45.37%) and hemicryptophytes with 42 species (35.29%) were the most abundant life forms in the region. In terms of geographical distribution, most species belong to pluriregional (27.50 %) and Irano-Turanian elements (18.33 %). In addition, the current results led to the identification of three and 15 new species for Afghanistan and Logar Province, respectively<br /><strong> </strong> https://cjes.guilan.ac.ir/article_7694_2e7a5d33c5c90638e90081f26b8b9188.pdf
