Comments
Echinopsis aurea Britton & Rose is a relatively dominant species, widespread in various provinces of northern Argentina (Catamarca, Córdoba, La Rioja, Salta, San Luis, and Santiago del Estero). The populations show quite variable characters, even within the same population, as highlighted in our surveys, so much so that some of these characters were taken as indicative of infra-populational (var.), intra-populational (ssp.), or at species level, taxonomic distinction. In reality, these distinctions fail when it emerges that the different characters that should define the supposed taxa are detected within the same population. For example, in the surveys of Córdoba, San Marco Sierra, road to Rio Quilpo, 19/Mar/2011, A&M 379, the strongest form, with more offsets and with more stems (largest stem 23 x 10.5 cm, h x d), i.e. characters that should distinguish Echinopsis fallax (Oehme) H. Friedrich (photos 5-8), lives near to the classic form of E. aurea (photos 13-14). Even in the survey of La Rioja, Olta, road to the Dique de Olta, 31/Mar/2011, A&M 414, there are both of the forms, E. fallax (photos 15-17) and E. aurea (photos 18-19), as well as the intermediate forms (photos 20-24). In addition to the forms of growth, also the "distinguishing" dimensional values, the number of ribs, spines, etc., which would separate the three taxa, can be found within the same population. For these reasons, we believe that E. fallax and E. aurea ssp. shaferi are synonyms of E. aurea. The idea is not new. Anderson (2001, 258) had already arrived at the same conclusion, mantained in Das grosse Kakteen Lexikon (2005, 2011), the German edition of Anderson’s book, translated and edited (with some taxonomic changes) by Eggli.
