Dioscorea trifurcata is a poorly known species with two specimens collected in 1910 and 1916 in Catamarca province, Argentina. But, recently the species was cited for Brazil, and populations were located near the type locality. With new collections available, the purpose of the article is to update aspects of the morphology, habitat and distribution of D. trifurcata. M&M: Specimens newly collected in Catamarca province were analyzed and identified to species using specific bibliography and by comparison with the original material of Dioscorea trifurcata and from other specimens of Dioscorea at different herbaria. Results: A detailed morphological description of Dioscorea trifurcata is provided along with illustrations, photographs and a geographic distribution map. The presence of the species in Brazil is questioned. Conclusions: The rediscovery of Dioscorea trifurcata opens the possibility of conducting new studies based on multiple lines of evidence to corroborate the delimitation and distribution of the species. The importance of regional herbaria and of having recent and complete collections of poorly-known species for the inventory and conservation of biodiversity is highlighted. Introducción y objetivos: Dioscorea es el género más diverso morfológicamente, más rico en especies y con mayor distribución de la familia Dioscoreaceae. Dioscorea trifurcata es una especie poco conocida, con dos ejemplares recolectados en 1910 y 1916 en la provincia de Catamarca, Argentina. Sin embargo, recientemente la especie fue citada para Brasil y se localizaron nuevas poblaciones en cercanías a la localidad tipo. En virtud del nuevo material disponible, este artículo tiene por finalidad actualizar aspectos de la morfología, hábitat y distribución de D. trifurcata. M&M: Los nuevos ejemplares recolectados en la provincia de Catamarca se analizaron e identificaron a especie utilizando bibliografía específica y por comparación con el material original de Dioscorea trifurcata y de otros ejemplares de Dioscorea en diferentes herbarios. Resultados: Se brinda una descripción morfológica detallada de Dioscorea trifurcata junto con ilustraciones, fotografías y un mapa de distribución geográfica. Se pone en duda la presencia de la especie en Brasil. Conclusiones: El redescubrimiento de Dioscorea trifurcata abre la posibilidad de realizar nuevos estudios basados en múltiples líneas de evidencia para corroborar la delimitación y distribución de la especie. Se destaca la importancia de los herbarios regionales y de contar con colecciones recientes y completas de especies poco conocidas para el registro y conservación de la biodiversidad.
