No detailed listing of the complete vascular flora of any woodland site along the Missouri River of east-central Nebraska has been published. This study provides a current annotated list of vascular flora at two private nature centers in the Omaha area, Fontenelle Forest and Neale Woods. Totaling about 644 hectares, the two preserves are located on loess bluffs adjacent to the Missouri River valley, with Fontenelle Forest also containing floodplain forest. A total of 597 species are distributed among 100 families and 331 genera between the two sites, representing approximately one-third of the known vascular flora for Nebraska. Comparisons are made between these two similar sites in the numbers of taxa, major vascular plant families, species growth habit. habitat, and origin. Additionally, the study compares current Fontenelle Forest flora to collections from the 1950\u27s, and examines possible future changes in the flora at both Fontenelle Forest and Neale Woods
