Abstract
A new species of Curcuma L. subg. Curcuma (Zingiberaceae) from China, C. ruiliensis N. H. Xia & Juan Chen, is described and illustrated. The chromosome number (2n = 84) is reported here. The new species is most similar to C. kwangsiensis S. G. Lee & C. F. Liang, but distinguished by pale yellow rhizomes, obovate tubers, longer ligule, lanceolate, obliquely spreading coma bracts, apex attenuate never obtuse, not reflexed, densely imbricated, lanceolate to ovate, obliquely spreading fertile bracts, apex narrowly acute never obtuse, not reflexed or slightly reflexed, larger flowers, longer calyx and fan‐shaped labellum.
