Grytsak L. Primula L. Genus (Primulaceae) in the flora Ukraine (taxonomy, phytochorology, evolution)

The object is Primula genus is the flora of Ukraine. The aim to investigate Primula species composition, their systematic position, chorological and ecological peculiarities. There have been used methods by I.O.Rabotnov, E.S. Smirnova, I.V.Vainagy. It has been found out the taxonomic significance of macro- and micromorphological features of the genus, their variability in the alelomorphs of polymorphous spesies in dependence of cenopopulation specificity within the area. Phenotype changes of different alpine form of P. elatior (L.) Hill under growth have been investigated. There have been studied ontomorphogenesis peculiarities of P. veris, P. macrocalyx, P. elatior: subsp. elatior, subsp. poloninensis, P. farinosa, P. minima. There have been developed a new variant of taxonomic system of Primula genus in Ukraine's flora. The chorological analysis of Primula genus has been made. There have been made a suggestion about probable time and place of the genus origin.
