Abstract: Haustoria are the union between the plant and the host plant is a root like structure or structure that grows in and around another water and nutrient-absorbing structure. Viscum articulatum Burm f. belongs to family Santalaceae, an extra pharmacopeia drug of Ayurveda known as Madanga parasite on Diospyros melanoxylon Roxb. Belongs to family Ebenaceae. For proper scientific evaluation of the plant for its authentication, macroscopy, microscopy physicochemical parameters, phytochemical screening, qualitative and quantitative of V. articulatum has been carried out as per standard protocol. The haustoria morphology showed cylindrical, branched, long 4 to 12 mm in diameter, variable in length, surface faintly longitudinally striated, at places shows few. Fracture is short, fractured surface brown, externally brown in colour, odour aromatic, taste is bitter. Microscopically T.S. showed the Haustoria host plant with outer epidermis followed by 2 -3 layer palisade cells. Ground tissue nearly 6 to 7 pairs of vascular bundles, pericyclic fibres 6 to 7 layers, Xylem 4-5 celled pericyclic fibre is present in cortical zone and extended up to xylem tissue. The haustoria zone mainly consists of parenchyma cells with calcium oxalate crystals, stone cells and scleroids. Ample amount of starch grains, brown content and isolated oil globules are observed in V. articulatum can be helpful in identifying the plant in powder from and useful for the proper scientific understating of the future analysis.
