چکیده

Davallia mariesii T. Moore ex Baker, a member of the section Trogostolon (Copel.) M. Kato and Tsutsumi (Davalliaceae M.R. Schomb.), is lithophytic or epiphytic herb that grows on rocks tree trunks in montane forests. This study analyzed morphological, anatomical, micromorphological, palynological characteristics D. using digital slide scanner field-emission scanning electron microscope presented an expanded updated description. A circumendodermal band was observed anatomical structure stipe, making second species family Davalliaceae with such band. The frond studies revealed epidermal cells indusium were thicker than those epidermis both sides hypostomatic fronds stomata chambers present. Diacytic, anisocytic, tetracytic stomatal complexes abaxial surfaces. indusia covered numerous sporangia. Leptosporangium consisted apical cap, basal annulus, stalk. spore had ellipsoidal outline, monolete aperture, verrucae colliculate ornamentation. obtained results provide systematic data for phylogeny establish basis future taxonomic delimitation other taxa.

The importance of palynology in the taxonomy of genus Silene, based on pollen morphology

 In this study, the palynology of 33 species of Silene belonging to 15 sections was investigated to examine the correspondence between palynology, morphological sections and phylogenetic trees. The pollen grains were prepared using the acetolysis method. Quantitative and qualitative micromorphological features of pollens were investigated using light microscopy and scanning electron microscopy....
