This study is aimed at identifying the flora of the area remaining between Hankendi - Baskil - Kömürhan (Elazığ). The study used 3128 plant samples collected from the field of research between 2011-2013. As a result of the systematic assessment of the samples, 338 species of 74 families and 469 species of these species were identified in a total of 660 taxons, including 133 altes and 80 varieties. Two of these 660 taxons included Pteridophyta 658 in the Magnoliophyta section. 5 of the 658 taxons belonging to the Magnoliophyta section belong to the Pinophytina (Gymnospermae) 653" subdivision of Magnoliophytina (Angiospermae). 565 of the 653 taxons located in the subdivision of Magnoliophytina are classified in Dicotyledonae, and 88 are classified in Monocotyledoneae. The taxon numbers and proportions of the first 10 families with the most taxons in the field of research are in the form of Asteraceae 91 (%13.8), Fabaceae 76 (%11.5), Lamiaceae 56 (%8.5), Poaceae 49 (%7.4), Brassicaceae 43 (%6.5), Caryophyllaceae 36 (%5.4), Apiaceae 34 (%5.2), Rosaceae 26 (%3.9), Boraginaceae 25 (%3.8), Ranunculaceae 17 (%2.6). The first three species with the most taxons were Astragalus (3.5%), Centaurea (1.7%), and Salvia (1.5%). The taxon numbers and rates of these taxons determined in the field of the study according to the phytocographic regions: Multi-Regional and Unknown 358 (54.2 percent), Iran-Turan 236 (35.8 percent), Europe Siberia 37 (5.6 percent), Mediterranean 29 (4.4 percent). The distribution of life forms of taxons in our field according to the Raunkiaer system is as follows: Hemikriptofit 277 (42%), Terofit 210 (31%). 8), Kamefit 65 (%9.8), Cryptofit 58 (%8.8), Fanerofit 50 (%7.6). 60 of the 660 taxons identified in our research field are endemic. According to this, the endemism rate of taxons in our area was 9.1. The ratio of endemic species in the first three family with the most taxons is Asteraceae 31.5%, Fabaceae 20.5%, Lamiaceae 13.6%.
