Abstract
Floral morphology of Nelumbo nucifera is observed chiefly from the anatomical point of view. Vascular bundles in the peduncle have large tracheids. They are classified into five types. In the receptacle morphology of the central vascular bundles changes to typical collateral bundles which have xylem with many slender tracheids. The floral vasculature in the receptacle consists of two systems, central and cortical systems. The main vascular system of the perianth is supplied by a single trace from the central vascular system. These traces depart spirally. Traces to stamens are supplied from the cortical vascular system. Usually a single cortical strand supplies several stamens by the division of these strands. The comparative differences in floral vasculature to nymphaeaceous genera are following respects : 1) absence of girdling bundles at the base of the receptacle, 2) existence of typical eustele in the receptacle, 3) existence of a cortical vascular system.
