For morphological and anatomical analysis, light micrographs of stem and roots cross sections were analysed. The transverse section of BJ root (Fig. 6 a) clearly shows the three tissue systems, i.e.dermal, ground and vascular. A single epidermal layer, followed by multi-layers of parenchymatous ground tissue and intercellular spaces, characteristic of the root system are visible. In the centre is the vascular bundle; strands of phloem are observed to alternate with the xylem ridges. Four xylem ridges (a tetrarch) is clearly indicated in the cross-section.
