The purpose of this study is to provide descriptions of keys to the identification for the dicotyledonous rosettes of eastern Nebraska. Rosettes are defined as herbaceous, terrestrial, acaulescent cluster of leaves. Vegetative descriptions are provided for 113 species pf 56 genera. A key to the species, based on the descriptions, is provided for identification of the taxa. Field collections were made from October 1988 through July 1990, with most specimens collected from August through November 1989. Specimens were pressed and dried using commonly accepted herbarium techniques. Voucher specimens are deposited at the University of Nebraska at Omaha Herbarium (OMA). Rosettes were identified from personal experience, by growing seeds or transplanted rosettes in a greenhouse or by comparison and association with mature plants found growing with the rosettes in the field. Descriptions are based on the characteristics obtained from the pressed and dried specimens and supplemented by description from field notes on the fresh materials. Characteristics from specimens include leaf shape, leaf size, marginal configuration, surface vestiture, venation pattern, and subterranean morphology. Characteristics from field notes include distribution, habitat, odor, and the presence of latex.
