Abstract
The identity of Curcuma zedoaria(Christm.) Roscoe and its nomenclatural history are explained. Roscoe wrongly interpreted the basionym of this name and applied his combination to a different taxon, which is not even involved in Christmann's protologue. The first lectotypification applied the name to the species upon which Rheede's description of Kua was based. Study of living material reveals that the name C. zedoaria(Christm.) Roscoe is currently applied to several superficially similar taxa in different parts of India and SE Asia and there are no grounds to propose conservation of the name with a different type. To avoid more confusion, the identity of the plant representing C. zedoariain the sense lectotypified by Burtt (1977) is explained here and a colour plate depicting its morphology is provided. The plant described and depicted by Roxburgh as Curcuma zerumbetRoxb., a name usually cited among synonyms of C. zedoaria(Christm.) Roscoe, is found to represent the taxon that Roscoe had in mind while publishing his combination C. zedoaria(Christm.) Roscoe. Curcuma zerumbetRoxb. is illegitimate, however, and as there is no other name available for this taxon it is described here as Curcuma picta. The nomenclatural history of Amomum zerumbet J. König nom. illeg. and Erndlia subpersonataGiseke, names which are involved in the illegitimacy of C. zerumbetRoxb., is explained.
