The Order Ranales comprises 11 families of aquatic, herbaceous and woody plant species with hipogynous flowers, free carpels or instead a single carpel, perianth not very well differentiated in calyx and corolla. In the Santa Fe province there exist only three families with native woody species. They are: in the Lauraceae, Nectandra angustifolia (Schrader) Nees, ‘laurel amarillo’, and Laurus nobilis L., the common laurel, an exotic species growing subspontaneous in several localities in the province; in the Annonaceae, only Rollinia emarginata Schltdl., the ‘arachichú’ of edible fruits; and in the Berberidaceae, only Berberis ruscifolia Lam., the spiny ‘uvilla’ or ‘espina amarilla’. The present work contributes to the knowledge of this family providing keys to the identification of the different taxa based on morphological characters. The methodology consisted of a bibliographical review, consultation of national herbaria with important collections of the province (SF: Esperanza; SI: Darwinion, San Isidro; UNR: Rosario), and lab work to confirm their identity. It is here provided taxonomic information, illustrations and a distribution map.
