Twenty-six of about 130 kurgans higher than 3 m, distributed over an area of approx. 1500 km&lt;sup&gt;2&lt;/sup&gt;, were surveyed and the flora of 5 microhabitats within every kurgan (top, southern and northern slope, southern and northern foot) was examined. The richness of the kurgan flora is estimated at 305 species. Species of alien origin constituted 23% of the total flora, which indicates limited anthropogenic influence. Species of two classes, &lt;em&gt;Festuco-Brometea&lt;/em&gt; and &lt;em&gt;Stellarietea mediae&lt;/em&gt; were predominant, which also confirmed the semi-natural character of the kurgan flora. The lowest number of species was recorded on top, which was relatively rich in synanthropes, particularly therophytes (&lt;em&gt;Stellarietea mediae&lt;/em&gt;). The north side was richer in species than the south side of the kurgans. Steppe species were the most stable and important component of the flora of the slopes (45-47% of the species represented the class &lt;em&gt;Festuco-Brometea&lt;/em&gt;). The total flora of the foot contained more species and was more diversified than the flora of the slopes (although the mean number of species was similar in both habitats), but each species occurred at low frequency. There was a higher proportion of species which were introduced from the area surrounding the kurgans, e.g. weeds, halophytes, meadow species, as well as trees which are rarely found in the desert steppe zone. In spite of the small size of the kurgans, significant differences between the floristic composition of the various microhabitats were detected.</jats:p> The floristic differentiation of microhabitats within kurgans in the desert steppe zone of southern Ukraine Acta Societatis Botanicorum Poloniae
