Keim, F.D., Beadle, G.W. and Frolik, A.L. (1932) The identification of the more important prairie hay grasses of Nebraska by their vegetative characters (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 65)
It is convenient and sometimes necessary to identify the grasses in their vegetative stage of growth. This is especially desirable in a study of the vegetation of native hay meadows and permanent pastures. This key is prepared as a guide in the identification of the more important prairie hay grasses of Nebraska. The meadows are often harvested before the floral parts of many of the grasses appear. If it is desired, therefore, to study the botanical composition of the native meadows, it becomes necessary to rely on identification of many of the grasses by means of vegetative characters.
