The pathway of water movement in hydroids of Polytrichum was determined by the precipitation of an electron‐dense crystal (Prussian blue) in the transpirational stream. Hydrolysed end walls appear highly water permeable since Prussian blue granules were localized within the loose fibrillar network. Electron‐dense granules were found free in the lumen but not in the lateral wall or in the middle lamella. These results are compared with data from vascular plant tracheary elements.
