Cross Section through a Digitalis Flower Bud - The Gynoecium is in the center.
Note the swollen, central Placentae and the two narrow Locules that are almost completely
filled by Ovules.
Long Section through the Gynoecium of Digitalis - Note the spatial relationship
between the Pericarp, Locule, Ovules and Placentae.
Same as above with the Vascular Bundles labeled.
