The data on two new populations of Schivereckia podolica on the Sorochenskie Hills along the rocky foot of Barsuk limestone massive are given in the article. High-altitude limits of Schivereckia podolica dispersion are revealed for two independent populations on Barsuk mountain (46–103 and 55–104 meters correspondingly) also as the total high-altitude diapason of Schivereckia podolica dispersion in Sorochinsky mountains (46–104 meters). The origin of two new found populations is presumably connected with the known before Schivereckia podolica population disposing on the high salient slope of Barsuk mountain from where the seeds can be drive by wind and water. Flower-bud formation and early flowering of Schivereckia podolica on the Sorochinskie Hills dates from the middle of April, mass flowering takes place at the end of April–beginning of May, flowering finishes in the middle of May. In the summer of 2013 the most of plants formed fruits in the last ten days of May and dispersed seeds from the last ten days of June up to the beginning of July. We revealed the effects of autumn flower-bud formation and reflorescence from 28.10.2013 to 22.11.2013.
Keywords: Schivereckia podolica, biogeographic investigations, phenology investigations, Sorochinskie hills, Barsuk mountain, Samara Region.
