The new species Amorphophallus terrestris Hett. & C. Claudel is described and compared to its phylogenetically closest relatives.
In his private collection of Araceae in Thailand, Mr. C. Punpreuk cultivated a small, ground dwelling Amorphophallus species he collected in the province of Ubon Ratchatani. The plant was brought to the attention of the first author in 2007 and was recognized as a new species. It belongs to a small group of miniature species from eastern Thailand and Laos, which together form a monophyletic group based on recent molecular analysis by the second author. In cultivation we succeeded to pollinate one specimen resulting in fruit set showing characters deviating from the mainstream fruiting in Amorphophallus species, seemingly adapted to life close to the soil surface.
