Floral vasculature in the normal flower of A. intermeda ‘chenshengzhen’. All figures are presented in transverse section with the adaxial side upward, related primarily to the carpellary dorsal bundles [arrow (↑), CDBs] and parietal bundles [arrowhead (), PBs] supply. a Pedicel, displaying an outer ring and an inner region of vascular bundles. b Sublocular region, showing the ovuliferous zone. c Locular region, displaying the CDBs and the PBs. dg The upper part of the ovary locules, displaying an anastomosing vascular plexus is formed by the CDBs and PBs bearing branches each other, and merging some outer large bundles from the ovary wall. h Below the junction of the calyx tube, showing the calyx tube beginning to differentiate before the anastomosing vascular plexus fading out. il The floral tube, showing the gland emergence and petals beginning to separate. mp A fully differentiated floral organs, showing the development of petals, labellum, fertile stamen and two appendages. Bars = 100 μm. g gland; a appendage; s sepal; p petal; st fertile stamen; lab staminodial labellum; sty style
