We observe in this article that their complexifications give rise to two families of foliations of the complexification of M which coincide with the flow foliations induced by the complexified CR (1,0) and (0,1) vector fields tangent to M. As an application, we derive a new proof of the characterization of finite type in terms of Segre sets.Completely rewritten version, 42 pages Sujclass: Complex VariablesComplex VariablesVector field construction of Segre setstext
