We describe the classification of germs of holomorphic saddle-node vector fields Z at (0,0)∈ C 2 , up to analytical change of local coordinates. The classification of saddle-node foliations F Z , obtained by Martinet and Ramis, led to functional moduli. We reduce the conjugacy equation between two vector fields inducing the same foliation to a homological equation. We derive then a complete set of additional functional invariants for vector fields.
