The outline of transverse section of the pedicel is more or less triangular in Strelitzia nicolai Regel & Koem. Vascular bundles of pedicel are scattered within the fundamental tissue, but those just beneath the locule region are arranged into an outer region consisted of two - ring bundles and a central region with dis-persed small bundles. The bundles from the outer region enter the ovary wall, while those from the central region extend into the axile and become placental bundles which fade away gradually in prolongation. The caipellary dorsal bundles (cdbs), the accompanying bundles of the dorsals (abds) and the parietal bundles of ovary wall could be easily distinguished. Three cdbs finally enter the style via prolongation. The abds sep-arately extend into three stamens of the outer whorl of androecium. Two abaxial parietal bundles run upwards into the two stamens of inner whorl, while the adaxial one divide into two branches. The inner one of these branches is gradually separated from the outer one and moves towards the central axile, and finally fades away just when the style appears. The outer one is arranged in a line with the other four bundles which final-ly enters the median petal.
