Abstract

On the basis of molecular data, the present authors will recognize Crassula L. and Tillaea L. as distinct genera in the forthcoming account of the Crassulaceae for the Flora of China, Volume 8. Tillaea is represented in the Flora area, but Crassula sensu stricto is not. With this arrangement, the correct name for T. pentandra Royle ex Edgeworth, described from the Himalayas, would be a new combination based on Crassula schimperi C. A. Meyer, described from Ethiopian material but clearly synonymous. The taxonomic identity of the latter name has been overlooked by authors working on Asian floras. Therefore, the new combination T. schimperi (C. A. Meyer) M. G. Gilbert, H. Ohba & K. T. Fu is made here along with new combinations for two subspecies found in tropical Africa and formerly treated under Crassula: T. schimperi subsp. phyturus (Mildbraed) M. G. Gilbert, H. Ohba & K. T. Fu and T. schimperi subsp. transvalensis (Kuntze) M. G. Gilbert, H. Ohba & K. T. Fu.
