Abstract. We give upper bounds of the numbers of holomorphic sections of Veech holomorphic families of Riemann surfaces. The numbers depend only on the topological types of the base Riemann surfaces and fibers. We also show a relation between signatures of Veech groups and moduli of cylinder decompositions of flat surfaces.
