Comments

In the publication cactusinhabitat.org 2010, we recognised the population of Cereus P. Miller of Catamarca at the Dique El Jumeal (A&M 123, photos 1-2) as Cereus hankeanus K. Schumann, and not Cereus forbesii Otto. This is in agreement with the interpretation of Hunt et al. (2006, text: 39-40, 42) of the C. forbesii, C. hankeanus, Cereus validus Haworth group. The subsequent studies we conducted in habitat in 2011, between Argentina (Cordoba and Salta) and Bolivia (Tarija) highlighted, in accordance with Kiesling (1999, 2: 428), that the best description for the taxa in question is C. forbesii, and not C. hankeanus. The description of C. hankeanus is wrong, either it has less ribs or less spines than the actual population. Therefore we prefer to reintroduce C. forbesii, and insert C. hankeanus among its synonyms. With regards to C. validus, as is also mentioned by Hunt et al. (2006, text: 39-40, 42) Haworth’s description (1831) comparing it to Cereus tetragonus (Linnaeus) P. Miller (now Acanthocereus tetragonus) with reference to the spines on the hypanthium, leads us to think that he is not referring to Cereus as is currently conceived. Instead Cereus validus auctt. not Haworth is to be considered synonym with C. forbesii. (Quoted from: Anceschi & Magli 2013b, 43)
