A review of the infrageneric classifications proposed for Kalanchoe (Crassulaceae subfam. Kalanchooideae) from the earliest times up to 2000 Author Smith, Gideon F. 0000-0002-5417-9208 Ria Olivier Herbarium, Department of Botany, Nelson Mandela University, P. O.

TABLE 9. Infrageneric taxa, species, and infraspecific taxa treated by Maire (1977: 251–269) in Kalanchoe. The nomenclature as used by Maire is deliberately retained. However, author citations have been updated to reflect current practice, following the house style of Phytotaxa, and not according to Brummitt & Powel (1992). Where Maire published a designation, his name has been added to the author attribution. “ K.” = Kalanchoe.

#	Section	Species and infraspecific taxa included
1The correct citation is Kalanchoe sect. Stellatopilosae (Berger 1930: 404) Smith (2020c: 234). 2See Smith (2021b: 96–98). 3The correct citation is Kalanchoe subg. Kitchingia (Baker 1881: 268) Smith & Figueiredo (2018a: 169). 4See Smith (2022d: 88–89) for a discussion of K. subg. Bryophyllum. 5See Smith & Shtein (2021d: 247–248). Note that the illustration and, to a large extent the description of, K. daigremontiana (Fig. 2D) included in Maire (1977: 267) seem to rather apply to K. × houghtonii Ward (2006: 94) and not to K. daigremontiana.
