The present paper is concerned with the onset of Rayleigh-Bénard convection in an inclined porous layer with anisotropic permeability. Due to the temperature gradient and the inclination, a steady shear flow is set up. The critical Rayleigh number at marginal stability of this basic flow is calculated and the flow pattern occurring at convection onset is examined. It turns out that anisotropy in the permeability and the shear flow have an essential influence on the selected flow structure. Depending on the anisotropy ratio and the tilt angle, convection rolls are found either with axes parallel to the basic flow or with axes perpendicular to the flow.
