Introduction. This is a continuation of Part I, which appears in the same Journal. In the previous paper we take a Grassmann bundle GS(TM) over a compact simply connected irreducible riemannian symmetric space M and consider a G-orbit CV in GS(TM) by the isometry group G of M. For each Q? we can define a class of submanifolds in M, so is called, a ^-geometry. We moreover assume that ^ is a G-orbit which contains an ^-dimensional strongly curvature-invariant subspace. Then ^l? corresponds to a PSLA (g, σ, T) of compact semisimple Lie algebra g and two commutative involutions σ, r. PSLA's are algebraicaly divided into those of inner type and those of outer type. Our aim in this article is to prove the following
