Summary: | A taxonomic treatment of Trisetum Pers. and Grapitephorum Desv. in North America north of México is given. Eight species of Trisetum are recognized. Two species are endemic to the United States: T. orthochaetum (Montana) and T. projectum (California, Montana, and Nevada); Trisetum cernuum subsp. cernuum, T cernuum subsp. canescens, T montanum, T. sihiricum, T. spicatum van spicatum, and T. spicatum van pilosiglume are found in Canada and the United States; and T. spicatum var spicatum and T. spicatum var pilosiglume are found in Greenland. Two species, T. aureum and T. Jlavescens, are introduced. Trisetum florihundum Pilg. is chosen as a lectotype for Trisetum sect. Aulacoa Louis-Marie. The genus Graphephorum comprises only two species: G. melicoides ranging from Canada to the United States and G. wo!/ii endemic to the United States. RESUMEN |
