Four new names in Chinese and Vietnamese Zingiberaceae

During preparation of the account of Zingiberaceae for the nora of China, v olume 24, it was noticed that four species are illegitimately named, being later homonyms: Amomum thyrsoideum Gagnepain (1903), not Ruiz and Pavon (17 98), A. aurantiacum H. T Tsai & S. W. Zhao (1979), not Ridley (1920), Hedyc hium carneum Y. Y. Qian (1994), not Loddiges (1823), and Zingiber truncatum S. Q. Tong (1487), not Stokes (1812). Therefore, the following new names ( nomina nova) are proposed here, respectively: A. gagnepainii T. L. Wu, K. L arsen & Turland, A. neoaurantiacum T. L. Wu, K. Larsen & Turland, H. neocar neum T L. Wu, K. Larsen & Turland, and Z. neotruncatum T. L. Wu, K. Larsen & Turland.
