Abstract: Scanning electron microscopy was used to study the ultrastructure of the spermoderm of four perennial Gypsophila species observed in Bulgaria: Gypsophila trichotoma Wend., Gypsophila paniculata L., Gypsophila tekirae Stef. and Gypsophila glomerata Pall. Air dried seeds of each species were covered with carbon and scanned on electron microscope (JEM 1200 EX) at magnifications of 200 x, 300 x, and 600 x. The spermoderm of Gypsophila trichotoma and Gypsophila tekirae were differentiated from each other by the shape of epidermal cells and the surface of periclinal walls, indicating a definitive taxonomic separation range for these two species and supporting the concept of a separate range for the two taxons. Differences in the spermoderm ultrastructure of Gypsophila paniculata and Gypsophila glomerata could also be distinguished.
