The largest number of species has the following families: Fabaceae (16 species), Labiatae, Rosaceae and Compositae (10 species each), Scrophulariaceae, Umbelliferae (5 species each), the other families were represented by only 1, 2, or 3 species each. Analysis of the biological forms Analyzing the spectrum of the biological forms we discover that in the reserve hemicryptophyte dominate (41%) from the species identified. These are followed (21%) by the phanerophytes which together with therophites (24%) form another 43% from the biological forms, the rest being represented by the geophytes and the helohydrophytes (Fig.3).

Analysis of the biological forms Analysis of the floristic elements The analysis of the floristic elements mark out the dominant euro Asiatic elements, which among those central European sum up approximately 82 species (70%) from the reserve flora, forming more than half the floral elements which means that they constitute the floristic background of this reserve. Mediterranean and Ponto Mediterranean floristic elements, which are thermophile species found especially on the sunny slopes, form together 8%. However, the cosmopolitic species are also remarkable, representing 5% from the total species found in the reserve. The fact that the reserve in situated in sloppy area is confirmed by the presence of the circumpolar and even alpine European at the reserve level, together representing 7% of the total species (Fig.4). 46% 1%1%1% 5% 5% 2% 1% 5% 2% 14% 14% Daco.Balc Carp.

Analysis of the floristic elements Ecologic study of the cormophytes Humidity If we group the plants by their humidity regimen in which they are adjust to live here, we will discover that the most dominant are xeromesophilic (U2-U2,5) which 65 are 42% from the total of the identified species in the reserve, these being found in the droughtiest places, specially on the meadows. Notable are also the mesophilic (U3-U3,5) which have a percentage of 37%, and can be found in areas where the light is scarce or there is an excess in humidity, where the swamps dry up during the summer but nevertheless have an excess in moisture. The xerophilic (U1-U1,5) can be found in 5% and this shows the hot and arid summer climate, being especially noticed on the slopes that have a south exposure, covered with a small seam of clay soil. In a percentage of 6%, the mesophilical (U4-U4,5) species that prefer soils from humid to moist-wet, are found near lakes or where there is an excess in moisture all year long. Remarkable is the presence of the hydrophilic (U5- U5,5) and ultrahydrophilic (U6) species which together form 5% from the total of species, and can be found in the ponds or on their border where water is present all year round. The amphytoletant (U0) species can also be found in the reserve in a percentage of 6%, being the most adaptable for these special conditions (Fig.5). 22% 20% 4% 1% 5% 2% 1% 2% 2% 4% 28% U3 U3,5 U4 U2,5 U5 U5,5 U6 U0 U1 U1,5 U2,5 U2.5 Fig. 5. Ecological spectrum of humidity Temperature Mesothermal (T3-T3,5) appear in a percentage of 63%. Mild thermophilic (T4-T4,5) species appear in a percentage of 12%, which suggests that the climate in the reserve in a temperate-continental one.The amphylotolerant (T0) appear in 16% of the total. The cryophilic (T1) species are missing, and the microthermal (T5) species appear in a small percentage, only 1% (Fig.6). 9%
