Abstract

In recent decades, significant taxonomic and floristic studies have been conducted in Zanjan Province and in the present study we aim to provide an orderly and updated list of plants collected in these studies. We analized 35 different studies conducted in the province. The scientific names of introduced plants and their authors were updated based on POWO and GBIF. The geographical distribution and native status of the plants were done by referring to the Flora of Iran, Flora Iranica, POWO and GBIF. A total of 1817 species and subspecies of vascular plants belonging to 548 genera and 92 families were listed. Among the endemic and sub-endemic species of Iran, 352 are found in this province and the endemic rate of the province is 19.25%. Asteraceae with 233 species (13% of all species) and 71 genera (13% of all genera), Fabaceae (270 species, 15% of all; 24 genera, 4.5% of all), Poaceae (136 species, 7.5% of all; 59 genera, 11% of all), Brassicaceae (118 species, 6.5% of all; 49 genera, 9% of all), Lamiaceae (103 species, 6% of all; 20 genera, 4% of all), Caryophyllaceae (92 species, 5% of all; 22 genera, 4% of all), Apiaceae (76 species, 4% of all; 40 genera, 7% of all), Rosaceae (66 species, 4% of all; 17 genera, 3% of all) and Boraginaceae (65 species, 4% of all; 25 genera, 5% of all) are the largest families that comprise approximately 65% of species (n = 1160) and 60% of genera (n = 328) of the vascular flora of Zanjan Province. Astragalus (with 173 species) is the largest genus in the flora of Zanjan Province. The results of this study show that, 15% of Iran's endemic Astragalus is present in Zanjan Province and 22% (more than one fifth) of the total inventory of the Astragalus in Zanjan Province are endemic to the province.
