Austrocylindropuntia in Blätt. Kakteenf. 1938(6): 21. 1938 sec. Ritz & al. 2012
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.
Phylogenetics: Austrocylindropuntia as originally treated in Hunt (2006) was found as not monophyletic by Ritz & al. (2012). Austrocylindropuntia lagopus (K. Schum.) F. Ritter was found sister to the remaining species of Austrocylindropuntia and Cumulopuntia and was therefore segregated as a monotypic genus Punotia D. R. Hunt; see also note under Punotia.A
