The family Anacardiaceae, in the Order Sapindales, comprises 74 genera and 600 species of pantropical and temperate distribution in the world. In Argentina the family Anacardiaceae includes six genera, four of which are present in the Santa Fe province. The present work contributes to the knowledge of this family providing keys to the identification of its taxa based on morphological characters and an analysis of their geographical distribution. The methodology consisted of bibliographic revision, consultation of national herbaria with important collections of the province flora (SF, SI, UNR), lab work to confirm their identity together with the field experience of the authors. In the genus Lithrea Hook. & Arn., the ‘molle de beber’ L. molleoides (Vell.) Engl. has been cited but could not be confirmed so far. In Myracrodruon Fr. Allemão (=Astronium Jacq. subgen. Myracrodruon (Fr. Allemão) Barkley), there occur M. balansae (Engl.) D.A. Santin (=Astronium balansae Engl.); in Schinopsis Engl. two species: S. balansae Engl., S. quebracho-colorado (Schltdl.) F.A. Barkley & T. Mey. (=S. lorentzii (Griseb.) Engl.), and one alleged interspecific hybrid: S. heterophylla Ragon. & J. Castigl.; in Schinus L. five species and four varieties, all known as ‘molles’: S. bumelioides I.M. Johnst., S. engleri F.A. Barkley var. uruguayensis F.A. Barkley, S. fasciculata (Griseb.) I.M. Johnst. var. fasciculata y var. arenicola (Hauman) F.A. Barkley, S. longifolia (Lindl.) Speg. var. longifolia y S. molle L.
