Astragalus (loco weed) is the largest genus of flowering                   plants in the world and is especially well represented in western               North America, where there are over 400 species.  Nevertheless,                 its species have rarely been the subject of a biosystematic                     study.  Nine closely related annual members of the genus, native                to Arizona, California, and Nevada, have been chosen as an                      appropriate group for such a study.  The extent of morphological                divergence in the fruits and flowers of these plants, reflected                 in their previous assignment to three different  genera, is quite               remarkable.  The objective of the proposed research is to examine               the evolutionary processes which have brought about and preserved               this diversity.                                                                      Specifically, this study will 1) clarify phylogenetic                      relationships among the members of the study group based on                     anatomical, cytological, and genetic data, and 2) use data                      derived from the analysis of genetic variation to evaluate                      breeding systems, speciation processes, and levels of divergence                in the group.
