Anatomic studies and cytological obeservations of the floral nectary in Lonicera Japonice Thunb were studied with light and scanning electron microscopy. The nectary of Lonicera japonica is composed of an epidermis and nectariferous tissues

which occupies on the innerr lower siders of the basal part of the corolla tube belonging to perigonal nectary. Most of the epidermal cell formed one-celled epidermal secretory hair. The cuticle at the head of the hair consist of very thin areas alternating with very thick protruding areas. During the development of nectary tissues

the vacuole of secretory hair changed apparently and the starch occurred regularly decrease and increase change in nectariferous tissuce. At the stage of nectar secretion

the cuticle of secretory hair becomes detached from the cellulose wall and a large cavity is formed between them

this cavity is full of nectar which secreted through the thin areas of cuticle.
