Abstract
The taxonomy of the Trifolium longipes Nutt. complex (Leguminosae) in the western United States is reviewed. This polyploid complex consists of diploid, tetraploid, and hexaploid races having a base number of x = 8. For the most part, each race occupies a distinct geographical area. Keys to the three species recognized in this study and to the 11 subspecies of T. longipes in the restricted sense are provided. For each taxon a description and synonymy are given. Maps of the chromosome races and taxonomic entities are appended.Keywords
