Abstract

Transfusion cells have been recorded in the leaves of Ptilophyllum and Nipaniophyllum. In the former, the transfusion cells are found in close association with the vascular elements, while in the latter they surround the bundle sheath. The relationship is discussed with the plants possessing the allied types of arrangement of transfusion cells.
