Opis:: The aim of the present study was to analyse the occurrence of monoecious individuals in selected populations of Taxus baccata in Poland and Ukraine. The investigation showed the monoecy in Taxus baccata to be extremely rare phenomenon. Only four cosexual individuals were found in three by seven populations examines and the frequency of monoecy was 0.13% on average among 2986 trees verified. Isolated seeds were found on individuals with large number of male flowers. Only one tree was found with numerous macro- and microstrobiles.

Opis:: Vaccinium ×intermedium Ruthe, the hybrid of V. myrtillus and V. vitis-idaea, by contrast with the parental species is very rare plant and has a discontinuous geographical range in north-western Europe. This paper describes the morphology of V. ×intermedium from Polish populations occurring in part of Pomeranian Lakeland in comparison with both parent species. The results presented here confirm the suggestions of earlier research that V. ×intermedium displays intermediate characteristics of leaf and floral morphology concordant with hybrid status. Also, is discussed the problem of the isolating mechanisms between parent species and hybrid's ecology.
