Abstract
The new monotypic genus Hayarum K.Z.Hein, Prehsler, Saensouk & S.L.Low from Thailand, with the sole species Hayarum mirispathum K.Z.Hein, Prehsler, Saensouk & S.L.Low, is described based on comprehensive morphological and phylogenetic evidence. A detailed taxonomic account of the new genus, morphological comparisons with related genera, and brief observations on its flowering biology and spathe movement are provided.
