The complex two-plane Grassmannian G(2)(Cm+2) in equipped with both a Kahle
r and a quaternionic Kahler structure. By applying these two structures to
the normal bundle of a real hypersurface M in G(2)(Cm+2) one gets a one- an
d a three-dimensional distribution on M. We classify all real hypersurfaces
M in G(2)(Cm+2), m greater than or equal to 3, for which these two distrib
utions are invariant under the shape operator of M.
