Using the Parsons-Lee theory, we examined effect of shape anisotropy and wall-to-wall separation (H) on phase behavior hard parallelepiped rods with dimensions L, D, D ($L&gt;D$) in such narrow slitlike pores which only one homeotropic layer can form. The structures, including biaxiality, planar nematic layering transition as well to homeotropic, were studied for some separations range $2.5D\ensuremath{\le}H\ensuremath{\le}10.0D$ $H\ensuremath{-}D\ensuremath{\le}L&lt;H$.
