| Abstract: | Two new species, Alocasia evrardii and A. vietnamensis (Araceae, Colocasieae), are described and illustrated from Vietnam. Although A. evrardii was described previously by Gagnepain in 1942, also with a historical record from Cambodia, its name was not validly published. A key to the species of Alocasia in Cambodia, Laos, and Vietnam is provided. |

| Full Text | Recently, during fieldwork carried out by the Institute of Tropical Biology at Takou Mountain located in the Takou Nature Reserve in the Binh Thuan province of southern Vietnam, one of the present authors (H. T. Luu) collected a flowering individual belonging to the genus a Alocasia (Schott) G. Don. The morphological characters of the plant match those of a species originally described by F. Gagnepain (1942) as A. evrardii. Gagnepain’s name was based on gatherings made by F. Evrard in Dalat, Lam Dong province, Vietnam; by B. Hayata, also from Dalat; by L.-M. Cadière from Cua Tung, Quang Tri province, Vietnam, and by C. Thorel from Chedom, Peunongs, Cambodia. Among these, the present authors have not seen the material collected by Cadière. Unfortunately, Gagnepain did not provide a Latin description or diagnosis, which is a requirement for the valid publication for names published between 1935 and 2011, inclusive, under Art. 39.1 of the International Code of Nomenclature for algae, fungi, and plants (McNeill & al. 2012). The name is validated here with an English description and diagnosis and the designation of a specimen in the Paris herbarium (P) from Evrard’s gathering as the holotype. |
