Abstract:Outer ring (OR) and central region (CR) of vaseular bundles in pedicel of Alpinia henryi can be recognized . When OR and CR extend into sublocular region,the bundles of OR moves toward outside and increases in number from 13 to 40 scattered CR bundles are arranged into triangle and their number varies from 18 into 12．At the locular region,the CR bundles are arranged as 3 carpellary dorsal bundles, 3 parietal bundles，and 5-7 small placental bundles which fade away at the base ofprolongation．Outer large branches of the three carpellary dorsal bundles finally enter the calyx．At the base of the prolongation, three parietal bundles produce some transverse branches which become vascular plexus with branches of partial bundles and a few smalI branches originated from three carpellary bundles, but their bundles extend directly upwards．Finally，the adaxial parietal bundle splits up into 4 branches which runs up into a functional stamen while the two abaxial parietal bundles split up respectively into 2-3 branches going to the labellum ．The bundles of the vascular plexus finally enter petals，labellum and style．It suggested that the calyx contains not only bundles in three sepals but also in three absent stamens．The authors support the views that the labellum represents two absent stamens ofiilner whorI ofandroecium and the two glands are of modified gynoplural nectary.
