Abstract Throughout the entire period of cell growth, the microfibrils on the inner surface of the outer tangential walls of the epidermal cells of Vigna angularis epicotyls are running parallel to one another and their orientation differs from cell to cell. Although transverse, oblique and longitudinal microfibrils can be observed irrespective of cell age, the frequency distribution of microfibril orientation changes with age. In young cells, transversely oriented microfibrils predominate. In cells of medium age, which are still undergoing elongation, transverse, oblique and longitudinal microfibrils are present in quite similar frequencies. In old, non-growing cells, longitudinally oriented microfibrils are predominent. A decrease in the relative frequency of transversely oriented microfibrils with cell age was also observed in the radial epidermal walls.
