【 摘 要 】

A distinct interrupted zone is present in the haustorium of Cassytha filiformis a non-host specific stem parasite. Majority of the xylem elements in the vascular core are perforated. The graniferous tracheary cells were observed in the vascular core of haustorium as well as in the parasite stem for the first time. Histochemical studies confirmed the proteinaceous nature of granules. Tracheary cells containing granules were examined using scanning electron microscope. The structure in relation to function of the tracheary cells and their granules are discussed in the light of earlier work.
