abstract：:In the ovary of Aptenia cordifolia and Platythyra haeckeliana placentary papillae produce a slime containing polysaccharides and proteins. These papillae show two types of conspicuous vacuoles enclosed by rough ER cisternae and complexes of concentrically arranged rough ER. The enclosed vacuoles probably play an impor...
