The family Liliaceae comprises 220 genera and 3500 species of all temperate regions of the world. In Argentina the family Liliaceae includes 14 genera, though only three of them are present in Santa Fe: Asparagus L., Herreria Ruiz & Pav. and Nothoscordum Kunth. The present work contributes to the knowledge of this family providing keys to the identification of different taxa based on morphological characters and a map of their ecological and geographical distribution. The methods consist of a thorough bibliographical review, consultation of national herbaria with important collections of the province (SF: Esperanza; SI: San Isidro; UNR: Rosario), field work experience of the authors and lab work to confirm their identity. As a preliminary result only two adventitious species of the genus Asparagus L. were found: Asparagus densiflorus (Kunth) Jessop and Asparagus setaceus (Kunth) Jessop, both new citations for the province. The genus Herreria Ruiz & Pav. includes three native species: Herreria bonplandii Lecomte, Herreria montevidensis Klotzsch ex Griseb. and Herreria ophiopogonoides (Kunth) Niederlein. Finally, the genus Nothoscordum Kunth. comprises two native herbaceous species: Nothoscordum gracile (Dryand. ex Aiton) Stearn var. gracile and Nothoscordum montevidense Beauverd subsp. montevidense. Their geographical distribution is concentrated mainly in the north-central and eastern departments of the province. Taxonomic information, illustrations and a distribution map are provided.
