Abstract

The taxonomy and nomenclature of Kalanchoe ×vadensis (Crassulaceae subfam. Kalanchooideae) [hybrid formula: K. blossfeldiana × K. marmorata var. somaliensis], an artificially produced amphidiploid, are discussed and clarified. An amplified description is provided for the nothospecies. The name K. ×vadensis is epitypified.
