The structure of floral nectaries of ivy (Hedera helix) was investigated under light, scanning, and transmission electron microscopes. The nectar of ivy is located on top of the inferior ovary forming a distinct undulating disc between the base of petals and the style. The ivy nectary represents open and persistent nectaries. During consecutive days of anthesis, nectaries change their colour from green to brown. The secretory epidermis is covered with a thick, deeply striated cuticle, and nectar is released by nectarostomata. Epidermal cells exhibited plastids with plastoglobules and a few starch grains as well as vacuoles containing anthocyanins, the content of which increased during the successive days of anthesis and nectar secretion.
