SYNOPSIS Protoplasmic connections occur between both meristematic and non‐meristematic cells of plants. Evidence is presented that they are formed on the cell plate at division by the fusion of chains of vesicles 20 mμ in diameter, which come to lie along the axis of the spindle and between the daughter nuclei. These threads then are fixed in position by the coagulation of the cell wall between them. The origin of the vesicles is obscure but they may be derived by abscission from the Golgi bodies (dictyosomes) which are found around the perimeter of the spindle in division.
