Summary
The fine structure of the interspecific junction in the periclinal chimeraCytisus adami has been investigated. This non-division wall shows the occurrence of pits of normal morphology. The pit membrane is partially penetrated by structures closely resembling plasmodesmata. These plasmodesmata, however, do not show direct continuity across the wall. Connections where they are seen appear to be established by a process of bridging between two half-plasmodesmata. The results are discussed with reference to the reversibility of the differentiation of plasmodesmata and their mode of formation.
