Abstract:

In this study, the old-floor flora has been investigated. The work area is located in the B3 square according to the grid square system applied by Davis (1965). As a result of the diagnosis of samples collected from the area of the study, 219 species of 59 families and 467 species and substrate taxons of these species were identified. The distribution of the identified taxons according to the phytocographic regions is as follows: the Mediterranean elements (49), the European-Siberian elements (31), the Iran-Turan elements (19), the Oksin elements (6), the multi-regional and phytocographic areas (362) are unknown. The families with the most taxons are Asteraceae (50), Fabaceae (38), Lamiaceae (24), Poaceae (21) and Liliaceae (18) respectively. The most taxonic species are Centaurea (7), Alyssum (6), Silene, Astragalus, Trifolium, Lathyrus and Campanula (5). In the research area, 43 endemic taxons were detected and the endemic rate in the area was 10.86%. 13 of the identified taxons are a new square record for the B3 square.
