  We prove two inequalities for the complex orientations of a separating (Type
I) non-singular real algebraic curve in $RP^2$ of any odd degree. We also
construct a separating non-singular pseudoholomorphic curve in $RP^2$ of any
degree congruent to 9 mod 12 which does not satisfies one of these
inequalities. Therefore the oriented isotopy type of the real locus of each of
these curves is algebraically unrealizable.
