摘要：
A revision of the exclusively Malagasy Kalanchoe subg. Kitchingia (Crassulaceae subfam. Kalanchooideae) is presented, along with a detailed discussion of its history, nomenclature, taxonomy, and circumscription. We uphold Kalanchoe subg. Kitchingia as one of four subgenera that are presently recognised in the genus, the other three being the autonymic Kalanchoe subg. Kalanchoe [recorded from Madagascar, Africa, and Asia], Kalanchoe subg. Bryophyllum [recorded from Madagascar only], and Kalanchoe subg. Fernandesiae [recorded from southern and south-tropical Africa only]. Only two species, Kalanchoe gracilipes, with two varieties recognised, and Kalanchoe peltata, with three varieties recognised, are included in Kalanchoe subg. Kitchingia. We show that the long-overlooked name at new rank, Kalanchoe peltata var. mandrakensis, A revision of the exclusively Malagasy Kalanchoe subg. Kitchingia (Crassulaceae subfam.

We show that the long-overlooked name at new rank, Kalanchoe peltata var. mandrakensis, was validly published in 1948.
