The nothospecies name Kalanchoe ×edwardii (Crassulaceae subfam. Kalanchooideae) was published for the hybrid between the arborescent K. beharensis and the shrubby K. tomentosa, two Malagasy species. Two well-known cultivars, K. ×edwardii ‘Fang’ and K. ×edwardii ‘Rose Leaf’, or simply K. ‘Fang’ and K. ‘Rose Leaf’, have been selected and named from K. ×edwardii. To facilitate distinguishing between these two cultivars, differences between them are tabulated and discussed. A general discussion of aspects of interspecific hybridisation in Kalanchoe is provided.
