Tinospora Cordifolia Case Study
ABSTRACT
Tinospora cordifolia (Willd.) Miers, it is a large, deciduous, tropical climbing shrub found throughout India, belong to the family Menispermaceae. Pharmacologically, Tinospora has a wide importance in Ayurveda. Secondary growth is achieved by formation of multiple cambia and other showed by formation of single cambium by members of Menispermaceae. Anatomy of this climber shows formation of xylem plates, this formation of cambial variants is the result of normal activity of cambium but abnormality in conformation. Secondary xylem shows vessel dimorphism large as well as with narrow vessels and wider rays. Formation of ray cambia and de-differentiation in to vessels elements were observed in Tinospora. Other anatomical characters favored the scandent habit of the plant, which are discussed in given investigations.

Lenticels protrude out breaking the cuticle at number of places. Epidermis was consisted of single compact layer of isodiametric and thin walled parenchyma cells. A 2-3 cell layered hypodermis composed of parenchyma cells differentiated beneath it while the cortex was composed of bulk of thin walled parenchyma cells. Cortical cells showed heavy accumulation of oval to circular starch grains. Cortex is followed by Pericycle and is composed of thick walled cells which covered the vascular bundle formed a cap on it called pericyclic parenchyma. These fibrous caps formed circular outline with adjacent parenchymatous cells. Five to six vascular bundles were joined by interfascicular cambium and formed a ring of the cambium. 5-6th nodes 14-15 vascular bundles were observed which were formed because of action of fascicular and interfascicular cambium. Cambial rays were large, heterocellular and compound with procumbent cells. Pith was relatively small and consisted of parenchymatous cells showing heavy deposition of starch
