The micromorphology and elemental composition of epicuticular waxes were studied from the foliar upper epidermis of two species viz. Jasminum auriculatum Vahl. and Jasminum multiflorum (Burm. f.) Andrews, using Scanning Electron Microscopic-Energy Dispersive X-ray Analysis (EDX).The epicuticular wax crystals of J. auriculatum were needle-like and broad, often aggregating to form radiating clusters, while those in J. multiflorum were irregular in shape. The wax crystals of J. auriculatum comprised mostly of five elements with Calcium, Oxygen and Carbon in sufficiently larger amounts, while the waxes of J. multiflorum had seven major components with Silicon and Oxygen in large amounts. Carbon and Calcium were seen in lower quantities here. This variation in crystal composition needs to be further evaluated to assess whether they are species-specific and would be of aid in the systematic evaluation of the genus.
