Comments

Echinopsis buchtienii (Backeberg) Anceschi & Magli is a new combination published in cactusinhabitat booklet. South America 2011-2013 (Anceschi & Magli 2013, 37). For the phylogenetic hypothesis adopted for the assimilation of Cleistocactus Lemaire in Echinopsis Zuccarini see booklet (ibid., 22-29).
(June 2013)

For years, molecular analysis revealed the close relationship between

Echinopsis s.l. and the other genera within the tribe Trichocereeae, or subtribe Trichocereinae (Nyffeler 2002, 317, 319; Schlumpberger 2009; Lendel et al. 2006, unpubl. data in Nyffeler & Eggli 2010). Even more recent molecular analysis of Echinopsis (Schlumpberger & Renner 2012), clearly demonstrated that a cladistically correct interpretation of the molecular data, in the direction of a monophyletic genus Echinopsis, leads to the assimilation in Echinopsis s.l., as currently conceived (Anderson 2001; Hunt et al. 2006; Anderson & Eggli 2011), of Cleistocactus Lemaire, Denmoza Britton & Rose, Haageocereus Backeberg, Harrisia Britton, Oreocereus (A. Berger) Riccobono, Weberbauerocereus Backeberg and 10 other genera of the Trichocereeae/Trichocereinae.
We've dealt extensively with the subject, in the part devoted to the taxonomy in our last booklet (Anceschi & Magli 2013b, 22-29).
Our position is summarized in “The new monophyletic macro-genus Echinopsis. No risk of paraphyly, and the most convincing hypothesis in phylogenetic terms” appeared on Cactaceae Systematics Initiatives N° 31, pages 24-27 (August 2013).
