چکیده
In this stydy, flowers of Alhagi pseudoalhagi were structurally investigated with respect to cell-tissue manners in several developmental stages. Flowers had synsepalous calyx, papilionoid corolla and dark color wings with outstanding epidermal cells, attached keels which made closed corolla with vexillium, diadelphous and heteromorphy androecium. None of the organs had protective or secretary hairs. Anther characters were: tetrasporange, extrorse, longitudinal dehiscence, four wall layers (dicotyledonous) and secretory tapetum. Epidermal and subepidermal layers of calyx, corolla, ovary and attaching tissue of anther had phenolicic (tanin) and fatty based materials. Gynoecium was monocarpellate and epigynous, with anatropous and crassinucelate ovules, open style and disk shaped stigma. After miosis cytokinesis was simultaneous. When microspores were in mature stage embryo sac had not yet passed mitosis and nucleus were not made totally.
