Abstract

This study has been carried out between 2017 and 2018 in order to determine the flora of Alanbası and Bakırtepe (Yusufeli, Artvin, Turkey). The research area under review takes place in Colchic province of Euro-Siberian floristic area of Holarctic region and is found in the A8 square according to grid system of Davis. The study area lies between 780 and 2150 m elevation above the sea level. In this study, total 448 taxa belong to 75 families and 302 genera were determined. 16 of them belong to Pteridophyta, the remaining 432 taxa were Magnoliophyta, which included 5 taxa from the Pinidae and 427 taxa from the Magnoliidae. The largest families recorded were as follows: Poaceae (62 taxa), Asteraceae (57 taxa), Rosaceae (30 taxa), Fabaceae (28 taxa), Lamiaceae (26 taxa), Brassicaceae (20 taxa), Apiaceae (20 taxa), Boraginaceae (17 taxa), Plantaginaceae (11 taxa), Caprifoliaceae (9 taxa) and Orobanchaceae (9 taxa). The percentage of phytogeographical origins of 259 taxa was determined. The distribution of the taxa according to the phytogeographical regions was as follows: Avrupa-Sibirya with 161 taxa (31,5%), Iran-Turan with 81 taxa (15,9%), Mediterranean with 17 taxa (3,3%) and multiregional or of unknown phytogeographic origin with 193 taxa (49,3%). The life form spectrum of 391 taxon was as follows: Hemicryptophytes 127 taxa (24,9%), Cryptophytes 95 taxa (18,6%), Phanerophytes 62 taxa (12,1%), Chamaephytes 54 taxa (10,6%) and Therophytes 53 taxa (10,4%). The taxa that unknown the life form spectrum is 61. Endemism is 6,8% and included 35 endemic taxa and 63 non-endemic rare plants.
