Notes
Phylogenetics: Weingartia and Sulcorebutia used to be merged in Rebutia, e.g. by Barthlott & Hunt (1993), Anderson (2001), and Hunt (2006), but were recognized by Anderson (2005). The Rebutia s.l. assemblage was found highly polyphyletic by Ritz & al. (2007), and was shown to be separated into three well supported clades. One of these clades comprises species of Weingartia, Sulcorebutia and Cintia and includes the nomenclatural type of Weingartia. Ritz & al. (2007) suggested that all three could be merged into a single genus, for which Weingartia is the oldest name.A
Taxon standing
Category B. The genus is monophyletic based on phylogenetic studies that support the clade based on a sufficiently dense or even complete sampling, or support a monotypic genus as a distinct lineage, but do not provide a new taxonomic treatment at the species level. In many cases, older classical taxonomic synopses or a monographic treatment exist for these genera providing a reliable assessment of the species included.
