Аннотация
Morphological and embryological characters of the xerophilous species Allium crystallinum Vved., A. filidens Regel, and A. fritschii Khassanov et Yengalycheva (Allium subg. Allium) were compared. The morphology of flowers, the rate of development of male and female embryonic structures and correlations with bud dimensions were studied. The overall similarity of the embryonic processes and structures underlines the close taxonomic relationship of the species investigated as concluded from morphological and anatomical characters. However, several differences in embryological characters between A. filidens and A. fritschii confirm the separation of the latter species at species level.
