ПОШИРЕННЯ ДЕЯКИХ ПРЕДСТАВНИКІВ SCROPHULARIACEAE sensu lato НА РІВНИННІЙ ЧАСТИНІ УКРАЇНИ ВПРОДОВЖ ГОЛОЦЕНУ: ПАЛЕОФЛОРИСТИЧНИЙ І ПАЛІНОМОРФОЛОГІЧНИЙ АСПЕКТИ

Abstract

Results of the analysis of participation of pollen of some representatives of the fami­ly Scrophulariaceae sensu lato in palynofloras of the Holocene deposits of the plain part of Ukraine are considered. It has been demonstrated that fossil pollen of Scrophulariaceae occurs sporadically, in small quantities and, in most cases, its identification was reported at the family level, occasionally also at the genus level. Our main attention was focused on the generalization of our paleofloristic materials, with species-level identification of pollen grains of Scrophulariaceae, whenever possible. The data available at present can justify the participation of four species, Scrophularia nodosa , Verbascum phoeniceum ( Scrophularia­ceae s. str.), Veronica incana ( Plantaginaceae ), Melampyrum arvense ( Orobanchaceae ) in fossil palynofloras of the Ukrainian Holocene deposits. The data obtained for these types of paleofloristic data are consistent with the changes in the current taxonomy of Scrophularia­ceae , which must be taken into account when compiling specific lists of fossil palynofloras. Quantitative and qualitative diagnostic characters for these four species are generalized; these characters are recommended to be used in the practice of spore-pollen analysis for specific identifications of fossil pollen. Permanent pollen preparations on slides are deposited in the reference palynotheca of the National Herbarium of Ukraine ( KW-P ).
