By Laurel K. Anderton, Mary E. Barkworth

Grasses of the Intermountain Region is a amendment of the 2 grass volumes of the Flora of North America (FNA). it really is designed for deciding on contributors of the Poaceae within the area among the Sierra Nevada and Rocky Mountains, and is meant to be used by means of botanists operating with the grasses during this intermountain zone of North the USA. The aid in variety of taxa incorporated from FNA has diminished the size of the keys and made it attainable to incorporate, in one quantity, descriptions and illustrations for all taxa taken care of in addition to offer distribution maps for species which are confirmed within the quarter. one other distinction from the FNA volumes is that the maps during this quantity convey in basic terms files from IMR and adjoining components instead of the entire North the USA variety of the taxa.
