Bast fibres are long extraxylary cells which mechanically support the phloem and they are divided into xylan- and gelatinous-type, depending on the composition of their secondary cell walls. The best fibres occur in the outer portion of the stem, interspersed with thin-walled tissues of phloem. The secondary phloic fibres, which are the derivatives of vascular cambium, are found lacking, though there is formation of secondary phloem pyramids from the cambial tissue.
