Abstract
The purpose of this paper is two fold: first, to present a list of Nebraska grasses; second, to present a plan for a system of illustrated keys by which these grasses may be more easily identified.
A list of Nebraska grasses should include all species both common and rare which might be found in this region. This list necessarily changes from time to time as cultivated or weedy species are introduced or as new endemic species are identified. The list included in this paper is proposed to contain all the native or naturalized grasses that have been reported as growing in Nebraska.
A plan for a system of illustrated keys emphasizing the importance of the spikelet in grass identification, is here presented. In this plan for the keys, Tribe X-Festuceae, is worked out in considerable detail as to keys, illustrations, and descriptions of the species. This tribe is the largest of the tribes of grasses in Nebraska. The other nine tribes are worked out in skeleton form which complete keys but incomplete as to illustrations and descriptions for species identification.
