Sketches showing the vascular anatomy of Magnolia denudata. For abbreviations, see caption for Figure 1. Red color for xylem, and black for phloem. a. Cross section showing ovarian locules, carpels around the floral axis (white broken line), collateral stelar bundles in the center, and amphicribral cortical bundles in the cortex. b. Three dimensional diagram showing a carpel attached to the floral axis, collateral stelar and amphicribral cortical bundles, ventral and dorsal bundles derived from the stelar bundles. c. Cross section of a carpel showing the deployment of collateral stelar bundle, collateral ventral and dorsal bundles, amphicribral cortical and ovular bundles, and lateral bundle. d. Anastomosis of cortical bundles and their relationship with ovules and lateral bundles in carpels.
