The viability of the rare plant species populations, including also the relict species, indicates a population decline due to the independent or simultaneous action of several factors such as: habitat quality, population size and genetic diversity. This paper aims to synthesize the studies conducted over time both on Ligularia sibirica species and Ligularia genus. The main objective of the paper is to identify the following research steps necessary for the optimal characterization, monitoring and conservation of the studied species and of its related populations. Ligularia genus includes species adapted to different climatic and environmental conditions from the European and Asian continent. Following the collected scientific material which holds data about L. sibirica, the author found a total of 166 bibliographic sources, of which 107 belong to Romania. The number of scientific materials found in Romania is correlated with the distribution of the L. sibirica species in the country. At European and Asian level, have been carried out phytosociology, genetics, biochemistry, biotechnology and phytopathology studies on Ligularia, while in our country taxonomic studies predominate, being part of some floristic surveys, monographs, etc., which need to be updated and completed. It can be noticed that biochemical and cytotoxical studies could bring new perspectives on L. sibirica benefits.
