Location of the postgenital fusion in the gynoecium of Capsella bursa-pastoris (L.) Med.

Some methods, based on the characteristics of the epidermal outer cell wall, for finding the exact location of a postgenital fusion were tried on the false septum in the gynoecium of Capsella bursa-pastoris (L.) Med. Electron microscopical demonstration of the remnants of the enclosed cuticles proved a reliable means for locating the suture at the place of fusion in the septum.
