(Crassulaceae) from northeastern Madagascar is described and illustrated: Kalanchoe darainensis D.-P. Klein & Callm. Morphologically, Kalanchoe darainensis is most similar to Kalanchoe blossfeldiana Poelln. and Kalanchoe globulifera H. Perrier which are known from the northwestern Tsaratanana Massif, c. 100 km southwest of Daraina. Detailed notes on the habitat and ecology of Kalanchoe darainensis are provided, as well as a short taxonomical overview of allied species of the Kalanchoe subg.

Despite its restricted distribution in the protected Antsahabe massif, the new species is preliminary assessed as “Least concern” [LC] using the IUCN Red List Criteria.
