Data are presented on Oncoba, Caloncoba, Camptostylus, Dasylepis, Scottellia, Berberidopsis, Lindackeria, and Peterodendron, with special emphasis on development and anatomy of the gynoecium. A neutral view is preferred to the carpel theory. There appears to be a link between parietal and basal placentation. It is proposed to refer to this placentation as cupular. Several peculiarities are found, such as ‘ramification’ of the stigmatic canals, penetration of the embryosac into the chalaza, distal lobes on integuments, separate vascular traces to the lowermost ovules, etc.
