摘要：

Typhonium baoshanense Z. L. Dao & H. Li (Araceae: Areae), a new species from western Yunnan, China, is described and illustrated. This species differs mainly from other species of Typhonium by the presence of one to two rings of sterile male flowers above the fertile male flowers, and from T. blumei Nicolson & Sivadasan by a conic female part of the spadix, the appendix not being truncate at its base, and by the angustate limb of the spathe. The chromosome number of Typhonium blumei, which occurs in same area, is 2n=52, while the chromosome number of the new species is 2n=10. The chromosome number of the new species is the lowest in the family Araceae.
