The identity of the little-known Kalanchoe lubangensis R.Fern. (Crassulaceae subfam. Kalanchooideae) is clarified. An amplified description is provided for this endemic species from southwestern Angola, aspects of its ecology are discussed, and it is illustrated. Kalanchoe lubangensis is compared to K. brachyloba Welw., a likely close relative. The natural geographical distribution range of K. lubangensis is extended to the Namibe province of Angola; previously it was only known from the Huíla province of that country.
