It is a dorsiventral leaf. Following tissues are present in midrib and lamina: Midrib (Figure 2a): Section passing through midrib represents convex shape. Midrib shows 5-6 layers of collenchyma below the upper epidermis. It shows collateral type of vascular bundles. Distinct phloem tissue can be seen on the ventral surface and well developed xylem tissue towards the dorsal surface of the midrib. Xylem shows presence of tracheids, xylem parenchyma, protoxylem, and metaxylem towards lower periphery. Tracheids are tubular and elongated, while xylem vessels are reticulate. Thick walled non-lignified phloem follows the xylem. Phloem parenchyma is present in the form of a broad patch with scattered phloem fibres. The vascular bundle is encircled with pericyclic layer. The pericyclic layer is composed of 4-6 layers of lignified, thick walled cells. Pericycle is covered with parenchymatous cells followed by presence of 2-3 layered collenchyma above lower epidermis. Leaf shows presence of cluster of calcium oxalate crystals and starch grains. It also exhibits presence of secretory cavities. Lamina (Figure 2b) The lamina of the leaf shows upper epidermis, mesophyll and lower epidermis. Upper epidermis is composed of flat single layer of rectangular cells. Mesophyll is differentiated into palisade tissue and spongy parenchyma. Palisade cells are single layered, elongated and compactly arranged while spongy parenchyma which is composed of polygonal cells irregularly arranged and fill the entire space of lamina. Lower epidermis
