Given a classical semisimple complex algebraic group and a symmetric pair of non-Hermitian type, we study the closures of the spherical nilpotent -orbits in the isotropy representation of . For all such orbit closures, we study the normality, and we describe the -module structure of the ring of regular functions of the normalizations.
