Marius Făgăraş / Ovidius University Annals, Biology-Ecology Series 14: 45-54 (2010) of Pontic elements (Fig. 4), the best represented in the studied area are: the Pontic-Mediterranean (55.31%), Pontic-Balkan (17.02%), Pontic proper (10.63%), Pontic-Pannonian-Balkan (8.51%), Pontic-Pannonian (4.25%), Pontic-Caucasian and Pontic-Central-European (2.12% each). The arid climate in the area of these hills is favorable for the large number of species of southern origin (Mediterranean, Sub-Mediterranean, Balkan), that make up a percentage of 11.78%. Table 2.

The spectrum of the Pontic elements Among the ecological categories connected to soil humidity (Fig. 5), we can remark the considerable percentage of xero-mesophile (57.3%) and xerophile (24.71%) species, components of the steppe meadows and of rock formation vegetation. The mesophile species (14.6%) are present especially in the forested area of the hills. The eurythermal species have a smaller percentage (2.8%).
Floristic aspects of the Hills of Camena village / Ovidius University Annals, Biology-Ecology Series 14: 45-54 (2010) From the point of view of the preference for temperature (Fig. 5), the micro-mesothermal (46.62%) and moderately thermophile (37.64%) species have considerable percentages, as they are regular in the silvosteppe zone which is made up of steppe meadows and forests. The thermophile species (6.17%) are encountered either in the steppe meadows or in the rock formations. From the point of view of the preference for soil pH (Fig. 5), the higher percentages are held by poor acid-neutrophile (53.37%), acidic-neutrophile (17.97%) and euryionic species (20.22%). We must remark the high percentage of acidophile species (2.8%), grouped on the acidic volcanites that make up the rock formations in the plateau zone. 70 60 50 40 % 30 20 10 0 U% T% R% 1-1,5 2-2,5 3-3,5 4-4,5 5-5,5 6 0 ecological categories Fig. 5. The spectrum of ecological categories The 19 rare and endangered taxa (Table 3) represent 10.67% of the total species and subspecies identified in the Hills of Camena. A more important element is the presence of the endemic species Campanula romanica in the area, but also of other rare and very rare plants at national level, mentioned in the Red Book of vascular plants of Romania [11]: Dianthus nardiformis (Fig. 8), Silene compacta, Moehringia jankaea, Iris sintenisii, Salvia aethiopis, Sempervivum zeleborii, Galanthus plicatus, Nectaroscordium siculum subsp. bulgaricum, Achillea coarctata, Crocus reticulatus, etc. In terms of the main endangered categories (Fig. 6), 1 taxon (0.56%) is endangered, 4 taxa (2.24%) are vulnerable, while 14 other (7.86%) are rare, with small populations at national level. 48 Table 3.
