title: Seed morphology of species of Spergula and Spergularia (Caryophyllaceae) occurring in Ukraine and its taxonomic significance
abstract: The micro- and macromorphological characteristics of seeds of species of the genera Spergula and Spergularia in the flora of Ukraine were studied in order to identify new diagnostic characters useful for solving taxonomic issues. The ultrastructure of the seed surface was studied using a scanning electron microscope. Seeds of some species of these genera are similar in appearance (especially with a wide wing — Spergula morisonii and Spergularia marina), which can be one of the confirmations of t
