title: DEVELOPMENT OF MALE REPRODUCTIVE STRUCTURES IN &lt;i&gt;CAMPANULA ALLIARIIFOLIA&lt;/i&gt; (CAMPANULACEAE)
abstract: A cytoembryological study of the formation of microsporangium wall and the development of pollen grains in Campanula alliariifolia Willd. was carried out. A significant similarity in the structure of male embryonic structures in this species with the other representatives of Campanulaceae was revealed, namely: simultaneous formation of tetrads of microspores, bicellular pollen grains with relatively large vegetative cell, cellular secretory tapetum, bilayered endothecium.
