transverse section one sees about 16 groups of tracheitis, each 
group being 2 to 6 cells thick in a tangential direction and about a 
millimetre long radially. Beyond each group of tracheitis, towards 
the periphery, is a phloem group separated from the xylem by 
cambium. Outside the phloem are first fibre-like cells with

mucilaginous walls and then true mucilage cells. The rest of the 
stem, i.e., the greater part of the tissue is composed of thin-walled 
storage parenchyma with much starch. In both cortex and medulla 
this is traversed by large mucilage canals and the cortex also
