The majority of the Kalanchoe species (Crassulaceae) that are indigenous to southern Africa have very wide natural geographical distribution ranges. Other kalanchoes from the subcontinent, such as the recently described K. winteri Gideon F.Sm., N.R.Crouch & Mich.Walters that was recorded from the Wolkberg Centre of Endemism, are narrow endemics. Kalanchoe crundallii I.Verd. is one of the species with a restricted distribution range. Although it was for the first time collected in the 1930s, and described in the mid-1940s, the species remains little known. We provide an amplified description for, and discuss and illustrate, the species. Based on available evidence we propose the retention of a conservation status of Rare (see  http://redlist.sanbi.org/redcat.php) for K. crundallii.
