%X The effect of the combined stratification on natural convection about a vertical surface in a porous medium is studied. This article reports a similarity solution and the Von Karman integral method for buoyancy-induced flow and heat and mass and mass flux from the wall is constant. Governing parameters for the problem are the buoyancy ratio N, Lewis number Le, thermal stratification parameter S_{2} and the solutal stratification parameter S_{2}. Results for Nusselt and Sherwood numbers are presented for wide range of governing parameters, and it is observed that both these physical characteristics increase with S_{1} and S_{2}.
