Abstract
Tacca ampliplacenta L. Zhang & Q.-J. Li sp. nova (Taccaceae) is described and illustrated from Yunnan province, China. It is distinguished by the following characters: the petioles, peduncles, and flowers are red wine-coloured instead of dark purple; the bracts are very similar to T. chantrieri, but the fruits have different intumescent placentas, which fill the fruit cavity; and the stalk of the infructescence is rich in flexible fibre and very tough. Its flowering period (July-August) is rather late as compared with that of the sympatric T. chantrieri (April-June). This phenological difference may play an important role in reproductive isolation between the two species.
