Staminate and hermaphroditic flowers show an hypogynous disc which is composed of two separate parts, an apical and a basal part. These histologic zones should be considered as nectaries. They differ by their position, their shape, and the content and state of differentiation of their cells. Basal nectaries are not vascularized but phloem bundles reach the tip of the disc. Initiation of nectariferous tissue occurs after that of the floral parts. The basal nectaries appear first but the number of cells still increases during the formation of the apical part of the disc. Both basal and apical nectaries have a superficial origin. Numerous anomocytic stomata are present especially on the surface of the apical nectaries; they are rounded and keep their stomatal pores open. On basal nectaries, however, they occur much less frequently.
