Anatomical description
Root
Stem (Culm)
Epidermis is the outermost single layered, composed of closely fitted tabular cells. Outer wall cuticularised. True cortex is absent, not differentiated into extrastelar and intrastelar regions. Next to epidermis, there occur several layer of parenchymatous cells, which contain abundant chloroplast that is, cells are chlorenchymatous. Then several cell-layer thick continuous band of sclerenchyma is present. Vascular bundle are closed and collateral remain scattered in parenchymatous ground tissue. They were more crowded towards the periphery. The bundle sheath was surrounded by sclerenchyma sheath; peripheral bundles touch the sclerenchymatous band. Xylem occurs in the form of letter “Y”-two metaxylem with larger cavities situated laterally that is, at the two arms of the letter “Y and two protoxylem vessels with smaller cavities in mature bundle lowermost protoxylem undergoes dissolution forming a cavity known as protoxylem lacuna and Xylem endarch. Phloem is above the two metaxylem vessels. Pith and medullary rays are not differentiated due to the scattered arrangement of bundles over the ground tissue (Figures 8 and 9
