In the present paper we present a survey of results concerning the variety of planar normal sections associated to a natural embedding of a real flag manifold . The results included are those that, we feel, better describe the nature of this algebraic variety of . In particular we present results concerning its Euler characteristic showing that it depends only on and not on the nature of itself. Furthermore, when is the manifold of complete flags of a compact simple Lie group, we present what is, in some sense, its dimension and a large class of submanifolds of contained in .
