Abstract :This study was carried out to reveal the vascular plant diversity of Çaltepe and Çeletepe. During 2015−2018, 2340 plant specimens were collected from the research area and 363 genera and 767 taxa belonging to 81 families were determined. Of all the collected taxa, 66 are endemic and endemism rate is %8.60. The IUCN threat categories of endemic and rare plants at global level are as follows: 1 taxon in “CR” category, as well as 4 taxa “EN”, 4 taxa “VU”, 9 taxa “NT”, and 45 taxa “LC”. Also, 3 rare taxa are found in the “VU” category, as well as 1 rare taxon in the “DD” category at regional level. 56 taxa are new records for the province of Bolu. The largest families in the study area are as follows: Asteraceae 97 taxa insert ignore into journalissuearticles values(%12.65);, Fabaceae 62 taxa insert ignore into journalissuearticles values(%8.08);, Lamiaceae 51 taxa insert ignore into journalissuearticles values(%6.65);, Rosaceae 44 taxa insert ignore into journalissuearticles values(%5.74);, Poaceae 37 taxa insert ignore into journalissuearticles values(%4.82);, Brassicaceae 35 taxa insert ignore into journalissuearticles values(%4.56);, Caryophyllaceae 32 taxa insert ignore into journalissuearticles values(%4.17);, Apiaceae 28 taxa insert ignore into journalissuearticles values(%3.65);, Boraginaceae 27 taxa insert ignore into journalissuearticles values(%3.52); and Orchidaceae 24 taxa insert ignore into journalissuearticles values(%3.13);. The distribution of taxa into phytogeographic regions are as follows: 234 taxa insert ignore into journalissuearticles values(%30.50); Euro-Siberian, 64 taxa insert ignore into journalissuearticles values(%8.34); Mediterranean, 46 taxa insert ignore into journalissuearticles values(%5.99); Irano-Turanian, and 423 taxa insert ignore into journalissuearticles values(%55.15); multiregional and/or unknown. Geranium and Silene insert ignore into journalissuearticles values(12 taxa); are the most common genera in the research area. These genera are followed by Salvia insert ignore into journalissuearticles values(11 taxa);, Trifolium, Veronica and Campanula insert ignore into journalissuearticles values(each with 10 taxa);, Ranunculus , Euphorbia and Vicia insert ignore into journalissuearticles values(each with 8 taxa);, and Poa insert ignore into journalissuearticles values(7 taxa);.
