Abstract
Cosmostigma cordatum
(Poir.) M. R. Almeida, Apocynaceae is a twining climber, it is used in
Ayurvedic and traditional medicine in a number of countries. Traditionally this
plant used for the treatment of ulcerous sores,
dyspepsia, wounds, chronic fever, diabetes etc. Its leaves are used
by tribals as a vegetable. The objectives of the present study were to describe
and analyse the morphology, organoleptic characters and powder microscopy of C.
cordatum. The results showed that the characteristics of plant morphology
were in accordance with the existing description in literatures.
Characteristics of inflorescence are specific characters of morphological
aspect of this plant. In powder microscopy, it was observed that multicellular trichomes of falcate type, epidermal
fragments (upper and lower), calcium oxalate crystals (rosette and prismatic),
starch grains, xylem vessels with spiral and pitted thickenings, fibres, brown
contents etc. were seen in the leaf powder. In the leaf powder analysis, it
was observed that anisocytic stomata in the lower epidermal fragments.
Therefore, the results based on the morphological, organoleptic and powder
characteristics can serve as useful parameters for the proper identification of
the drug and will validate the use of plant in traditional medicine.
