Leaf consists of four parts:

• A. Leaf sheath : it is the basal part of the leaf. It encircles the clum (stem) and protects the growing points and auxiliary buds.
• B. Blade : It is flattened, parallel veined portion of the leaf.
• C. Ligul : It is a membranous or cartilaginous fringe at the junction of the sheath and blade of the side of the leaf next tof clum. The continuation of the sheath through the color is known as legul.
• D. Auricle : Lobes of the leaf blade which extent downward on each side at the junction of blade and sheath. Some times it is coloured in stead of green.
