Abstract

Chamaelirium viridiflorum (Melanthiaceae), a new species from southern Jiangxi, China, is described and illustrated. It is similar to C. koidzumiana in their ellipitic or ovate leaf blade and slender petiole, but differs by its zygomorphic flowers and unequal tepals. Besides Chamaelirium viridiflorum is also similar to C. shiwandashanensis in their actinomorphic flowers, but distinguished by its spatulate to obovate leaf blade, distinct petiole and 0.8–1.1 cm long tepals. This new species has an obvious feature that the color of tepals is still greenish at the end of the flowering period.
