Gray species complex (Fabaceae) is a group of closely related clovers native to western North America. The group ranges from Mexico to the United States and Canada. Based on the most recent treatment by Vincent and Isely in 2012, the species complex includes five species, one of which contains two varieties. The taxonomy of the species complex has historically been unstable, so an analysis of morphological data was conducted from herbarium specimens to revise the taxonomy of the species complex. Principal component analyses and cluster analyses support five taxa that are recognized here: <i>T. bifidum</i>, <i>T. ciliolatum</i>, <i>T. gracilentum</i>, <i>T. oliganthum</i>, and <i>T. palmeri</i>. Additionally, the equilibrium model of island biodiversity’s predictions on rates of speciation were tested on specimens from the California Channel Islands and Guadalupe Island. The results support the model’s prediction of low rates of speciation in island systems that are close to the mainland. 2019-08-06 English text Miami University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=miami1565010559912396 http://rave.ohiolink.edu/etdc/view?acc_num=miami1565010559912396 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
