Abstract

Abstract
The Afus region with 1146 hectares area is located at 10 Km to Buin Miandasht region (Isfahan province) between the northern latitudes of 33° 05΄ and 33° 58΄ and the eastern longitudes 50° 02΄ and 50° 09΄. The purpose of the present study was to investigate the flora of the region. So, the plant species were collected from different places using the survey sampling method during spring, summer, and autumn 2017-2018 and were identified using valid resources. In this study, a complete list of the flora, life forms, chorotypes of plant elements, and endemic plants was prepared. The identified vascular plants in the region were mostly flowering with 184 species belonging to 37 families and 132 genera. Asteraceae (24 genera, 32 species), Apiaceae (12 genera, 12 species), Poaceae (11 genera, 13 species), and lamiaceae (9 genera, 13 species) were the most important families in this region, respectively. The largest genera were Astragalus (12 species), Euphorbia (5 species), Silene and Stachys (4 species), Cousinia, Fritillaria and Scorzonera (3 species) and Centaurea (2 species), respectively. The largest geographic floral element of the region was related to Irano-Turanian region with 136 species (73/9%). Hemicryptophytes (107 species, 58/15%), geophytes (25 species, 13/59 %), theophytes (24 species, 13/04%), chamaephytes (17 species, 9/24%), phanerophytes (7 species, 3/80%), and cryptophytes (4 species, 2/17%) made up the most important life forms, respectively.
