CO: collenchyma; CU: Cuticle; LE: lower epidermis, PA: parenchyma; PP: palisade parchyma; UE: upper epidermis; UT: unicellular non-glandular trichome; VB: vascular bundle. Briefly, scalpel was used to cut a tiny strip of the plants through the petiole. The transverse sections obtained were cleared using 2% v/v sodium hypochlorite, washed severally in water, stained with Safranin O, dehydrated in 50%, 70% and 100% Ethanol, mounted in dilute, glycerol, viewed under microscope and, photomicrograph was taken with the aid of phone camera
