Comments

Reading about the relationships between Rebutia K. Schumann, Sulcorebutia Backeberg and Weingartia Werdermann, and to our inclusion of Sulcorebutia in Weingartia, on the basis of molecular studies’ results (Ritz et al. 2007; Nyffeler & Eggli 2010) we refer to our comment on Weingartia rauschii(G. Frank) F. H. Brandt that appears in this same booklet (see pages 84-87). Regarding the relationship between Weingartia krahnii (Rausch) F. H. Brandt and Weingartia steinbachii (Werdermann) F. H. Brandt, the subject of this comment, we agree with Anderson (2001, 609-610), in including W. krahnii together with Weingartia tiraquensis (Cárdenas) F. H. Brandt in the synonymy of W. steinbachii, considering the first two taxa only variants in spination of the third. In this regard, one should note the extreme variability of the spines both structurally and chromatically, within the same population of W. krahnii (see A&M 1321, 30 Jan 2016 & A&M 1323). Also noteable is the difference in habitat between young and adult semaphoronts (see A&M 1323, photo 48, for the two side by side), hardly connected to each other if we hadn't been able to study all the distinct phases of the taxon’s ontogenesis during our 9 days stay in Comarapa, Santa Cruz, Bolivia, from 28 Jan to 5 Feb 2016. By sharing Anderson's concept (ibidem), in relation to this group of taxa, we exclude the hypothesis that W. krahnii is a part of Rebutia glomeriseta Cárdenas, as supported by Hunt et al. (2006, text: 314; atlas: 259, 259.3 (in the atlas as Sulcorebutia krahnii). In this respect, we recall that Lowry & Carr subsequently considered S. krahnii as part of Rebutia steinbachii Werdermann (data gathered from: Lowry, M. & Carr, J. 2017. Rebutia steinbachii (amended version of 2013 assessment). The IUCN Red List of Threatened Species 2017. Downloaded on 07 January 2020). To complete the picture of the synonymy in W. steinbachii, as in Anderson (2001, 609-610), we consider Weingartia totorensis (Cárdenas) F. H. Brandt and Weingartia lepida (F. Ritter) F. H. Brandt (together with Sulcorebutia aguilarii hort. (Anderson & Eggli 2011, 612), as part of the first taxon. (Quoted from Anceschi & Magli 2021, 87-88)
