a Cross-section through an ovary of C. hirtella. The ovules are anatropous with the micropyle facing outwards b Cross- and longitudinal section of a C. megarrhiza fruit. The seeds are enclosed in a hyaline hull (aril) and seemingly attached to the periphery c Cross-section through a fruit of C. sessilifolia. Note that the vascular bundles in the lower left of the picture bend in the periphery, so the placentation is not parietal but involute.
