The vein-terminations are distinct, short thick and unbranched; the islets are random in orientation (Fig 6A). Along the vein calcium oxalate druses are located in regular uniseriate row. The crystals are spherical, spiny bodies of 30 μm in diameter (Fig.6B). type and are long, narrow, tapering towards the tip. The cell walls are fairly thick and smooth. The trichomes have no cell inclusions with 1.05 mm long and 30 µm in thickness. Fig 6.

VT:- Vein Terminology Powder Analysis The leaf powder of Urena lobata Linn was greenish in colour, with punget odour and characteristic taste. Powder analysis observation cited that Non glandular trichomes and A cluster of trichomes (Fig7 A&B). Epidermal trichomes are presented as unicellular and unbranched in the powder .The trichomes are non glandular Volume 3, Issue 1, Jan. − Feb. 2013 7. Powder microscopy of trichomes A. Non glandular Trichomes, B. Cluster of Trichomes Fragments of fibers which are thick, narrow and wide (Fig 8 A, B&C). Parenchyma cells are wide and narrow, elongated, rectangular and thick walled seen in isolated condition. They have thick cellulose walls and wide circular simple pits. The cells are 250-350 µm long and 30-70 µm wide. Fibers (xylem) widely spread in the powder. They are long and thin in the middle and gradually tapering the ends. The walls are thick and lignified and the pits on the walls are not evident. Some of the fibers are narrow and others are wide 27 | P a g e http://www.ijpi.org

A, B & C). The vessel elements are long, narrow and cylindrical. Their walls are fairly thin. The pits on the lateral walls are wide, circular, either oblique or horizontal in orientation. The vessel elements are 350- 600 µm long and 50µm wide. Fig 9. Vessel elements of Urena lobata Linn leaf CONCLUSION The present study on pharmacognostical studies on Urena lobata Linn includes the exomorphology histological and powder microscopical evaluation of the leaves. This provides helpful information with regards to its correct identity and to differentiate from other closely related species. The study of microscopic characters of the plant shows the presences of identifying characters which help for the future works on Urena lobata Linn. REFERNCES 1.
