Infinitesimally Desarguesian two-parameter families of curves in the plane which are in a sense close to the family of straight lines are discussed. Their properties, examples, and multidimensional generalizations are considered.
Keywords: local projective structure, rational curve, infinitesimally Desarguesian family, horosphere, symmetric space.
