Creator(s): N. P. Smith
Description: Cross section of an ovary of Gustavia grandibracteata based on Mori & Kallunki 5612 from the Canal Zone, Panama. Note that the ovules are anatropous and that the micropyle faces toward the placenta. In addition, the inner integument extrudes beyond the micropyle and, thus, forms the micropyle.
