The author computes the divisor class group of the semigroup of highest weights for irreducible representations of a connected semisimple algebraic group whose highest weight line is preserved by a fixed parabolic subgroup. This extends the result of the reviewer [J. Algebra 168, No. 3, 773-779 (1994; Zbl 0810.20051)].
