Notes
“Cumarinia” is a monotypic genus. Cumarinia odorata was described as Coryphantha odorata by Bödeker in 1930, transferred into the genus Neobessaya by Werdermann and thence to the new genusCumarinia by Knuth which, in turn, was reduced to a sub-genus of Neolloydia by Backeberg in 1942.
The name Cumarinia has persisted, probably because it is far from being a typica Neolloydia species. Additionally it does not fit into the Neolloydia mould on account of its hooked central spines, it has also many differences from the Coryphantha so, it is a good genus according to The New Cactus Lexicon (2006) nowadays.
