Abstract: The flower nectaries of Calligonum ebi-nuricum Ivanova are located at the base of stamens and stretch to receptacles, which are also called Stamens nectary. The Nectary is composed of secretion epiderm, melliferous organization and vascular bundle. In the process of flower development, the nectary split up or differentiates from their original cells. And during the ontogenetic process, the floral nectary shows a vacuolization dynamics from what can be seen or known. The PAS reaction tests that the cells are filled with positive materials. The way of Nectar secretion is that the honey is secreted to plants in vitro by the specialized trichomes. And its possible nectariferous mechanism is that the honey is made up of melliferous organization and secretes through a specialized secretory trichomes.

Key words: Calligonum ebi-nuricum, floral nectary, anatomy
