Peterson, Soreng, Romasch. & Barberá, gen. nov. (subtribe Echinopogoninae), Paramochloa P.M. Peterson, Soreng, Romasch. & Barberá, gen. nov. (subtribe Calothecinae), and Laegaardia P.M. Peterson, Soreng, Romasch. & Barberá, gen. nov. (subtribe Calothecinae) with two, two and one species, respectively. In addition to the 116 new taxonomic entities, we provide a key to the genera of American grasses presently or formerly treated in Calamagrostis or Deyeuxia and generic emendations for Cinnagrostis and Peyritschia.
