The Zone of Fibres (bast).—The longitudinal zonesof epidermis devoid of stomatal pores are on the otherhand underlain by a mechanical tissue composed ofmuch elongated cells (fibres). To each zone, and lyingjust below the fibres, is a vascular bundle (figure 4).According to the age of the stem and to the vertical])osition, the extent of fibrous varies, it being re-latively greatest in the lowermost part of the internode,and bears an inverse relation to the chlorenchymazones. Here the fibrous underlies the chloren-chyma zoius, thus forming a continuous layer of me-chan
